Recovery from failure question

In order to use two racks of servers (in our case located in separate buildings) and make sure that primary and backup (backup count 1) of each partition are allocated to nodes in different racks I have understood that there is a "machine id" that can be assigned to each node.
     As far as I understand it the cluster will (when configured this way) survive failure of one rack (as long as no more failures occur before the other rack is online again), ie it will execute in a lower "safely mode". I have two questions about this:
     1. Lets say that one rack looses connection with the rest of the network long enough for the cluster to consider the other rack to be down. This will happen with both racks. What happens when the racks once again can communicate? Will they automatically sort out the "split brain" situation?
     2. Lets assume that one of the racks A is hit by a power spike that causes the switch and all the servers except one to rebooted. This will totally cut the failed rack off from the other rack while the switch re-boots and the nodes in rack B will consider all nodes in rack A to be down. After the switch is re-booted the nodes one still working server in rack A will be able to communicate with the nodes in rack B again. My question is then if Coherent in this situation will try to creating backups for all partitions of rack B in the nodes on the single available server in rack A? If this is the case the nodes in that server will most likely quickly run out of heap. What will happen in this situation? Will coherence retry - rebalancing when more nodes join the cluster or will the cluster crash?
     Best Regards

     Never is not exactly true. Only if it is theoretically possible to fit all the data in distinct nodes. But e.g. if you have two boxes, with the cluster nodes on one of the boxes not providing enough capacity to hold an entire copy of the data-set, the two copies still have to exist, then inevitably some of the duplicate data will end up on the nodes on the larger box, since they cannot fit into the smaller one. Also be aware that data distribution is done with the granularity of partitions. You cannot distribute a single partition to two nodes, so too uneven partitioning of the data-set can lead to problems.

     While and immediately after you are losing nodes (when their death is detected) partition backups will be attempted to be promoted to primary copies. This might cause OutOfMemoryErrors in those nodes. I do not know if Coherence is able to recover from that (theoretically it should be possible to drop the newly created object references to get back to the state before the attempt to promote the partition backup to a primary partition).
     So during nodes dying you can either temporarily or permanently lose access to data for which primaries were on boxes which died and the reconstruction from the backup caused OutOfMemoryError. If the Coherence JVM is not able to recover from that OutOfMemoryError then you might lose other primaries which reside on this cluster node and have a ripple effect because of this.
     You can reduce the risk of such events by having more than two racks if multiple nodes in racks can fail together, and also sizing the cluster JVMs to have lower memory utilization due to cached data. This way a rack failure will cause for one less primaries lost and for two, more free memory to reconstruct data in. You can read the Production Checklist for some information on sizing the cluster.
     Whatever happens, I don't expect that you will lose data due to OutOfMemory errors when you do not lose a cluster node. So after that blackout on one of the racks, and after the cluster reached a quiescent state as far as redistribution of partitions is concerned, you will not lose data just because you added back a node (I expect a copy of a backup is not dropped before the safe reception of the backup at the transfer destination is acknowledged).
     If there are not enough cluster nodes running on one of the racks to accommodate the entire data-set, your data will not be balanced in a way that copies of the same data are fully on different, but they will still reside on separate cluster nodes. When more nodes are started then gradually they will be rebalanced to hold more data on separate racks.
     Best regards,
     Robert

Data recovery from corrupt boot partition

The boot partition on my MacBook running 10.7.6 has a corrupt volume structure and will not mount, much less boot. The recovery partition boots but really doesn't let me do anything. Disk Utility can't repair nor even complete verification. I have lots of images which I need to recover, so am looking for a utility which might help.
Everything was apparently ok until the failure and the drive hardware checked out ok, so I'm hopeful my files are recoverable. A week or so ago I optimized the volume with TechTool Pro and the directory with DiskWarrior, and last night attempted to sync 1Password on my iPad with 1Password for Mac. This did no t work, probably because of my unfamiliarity with the procedure, but seemed to do no damage. When I ran TTPro last night from its eDrive partition it reported a volume structure problem on the partition which I started to fix with the program but then cancelled the analysis and decided to use disk utility instead. Disk utility also reported a problem but stopped the verification with the instruction to do a repair which it again could not complete. When I rebooted the system partition would again not boot but this time I got grey screen with a message that the debugger had loaded and <panic>. A message box said power down and restart, but that only repeats the process.
I'm thinking of attempting to install a system on an external boot drive and accessing the corrupt partition with a data recovery utility. Any insights, ideas or shared experiences appreciated. Thanks in advance for any desperately needed help.

The safest thing to do here is to install a new disk in the system and do a clean install of OS X. From there, you can put your corrupted volume in an external USB enclosure and mount the file system to try and recover as much data as you can.
It's likely obvious now, but it's REALLY worth investing in a large-capacity external storage or Time Capsure to use with Time Machine. Backups are essential. Hardware always eventually dies. We all need an effective strategy to deal with that.
A long time ago, I was backing my Linux system up to 4mm DAT. When the inevitable HDD crash came, I thought I was ready. Unfortunately, I hadn't tested recovery from tape and I ended up losing everything. Which is to say, until you know you can restore, you don't even have a backup. I lost thousands upon thousands of photos of my kids growing up.
BTW, if it is essential that you recover as much as possible, consider taking the disk to a data recovery service. Be warned: It's expensive.

Backup/Recovery from web application

Hello guys,
I am using Oracle 9i as DB and Oracle 9iAS for web application server. I want to provide Backup and Recovery functionality to the user via web. I don't know any thing in this regard.
Is it possible that we can take backup and recovery from web application?
Is there any alternative for this function.
any other comments will be appreciated.
Thank you,

Read this article in order to get an idea about Java Stored Procedures.
Oracle Developer JAVA STORED PROCEDURES
Simplify with Java Stored Procedures
By Kuassi Mensah
Use Java stored procedures to bridge SQL, XML, Java, and J2EE and Web Services.
Stored procedures allow a clean separation of persistence logic that runs in the database tier from business logic that runs in the middle tier. This separation reduces overall application complexity and increases reuse, security, performance, and scalability.
A major obstacle, however, for widespread adoption of stored procedures is the set of various proprietary, database-dependent implementation languages that different database vendors use. The use of Java-based stored procedures fixes this concern. Oracle has implemented ANSI standards that specify the ability to invoke static Java methods from SQL as procedures or functions. This implementation is called simply "Java stored procedures."
In this article, you will learn how Java stored procedures help simplify and increase the performance of your business logic and extend database functionality. I'll show how Oracle enables the use of Java stored procedures within the database. I'll also look at how Java stored procedures access data, and show how to create a basic Java stored procedure.
PL/SQL or Java
When you think of Oracle stored procedures, you probably think of PL/SQL. Oracle, however, has provided Java support in the database since Oracle8i, to offer an open and portable alternative to PL/SQL for stored procedures. I can hear the $64,000 question: "How do I choose between PL/SQL and Java? Should I forget all the things I've been told about PL/SQL and move on to the greener Java pastures?"
Both languages are suitable for database programming, and each has its strengths and weaknesses. In deciding which language to use, here's a general rule of thumb:
Use PL/SQL for database-centric logic that requires seamless integration with SQL and therefore complete access to database objects, types, and features.
Use Java as an open alternative to PL/SQL for database independence, but also for integrating and bridging the worlds of SQL, XML, J2EE, and Web services.
OracleJVM Lets You Run Java within the Database
Since Oracle8i, Release 1 (Oracle 8.1.5), Oracle has offered a tightly integrated Java virtual machine (JVM) that supports Oracle's database session architecture. Any database session may activate a virtually dedicated JVM during the first Java code invocation; subsequent users then benefit from this already Java-enabled session. In reality, all sessions share the same JVM code and staticsonly private states are kept and garbage collected in an individual session space, to provide Java sessions the same session isolation and data integrity capabilities as SQL operations. There is no need for a separate Java-enabled process for data integrity. This session-based architecture provides a small memory footprint and gives OracleJVM the same linear SMP scalability as the Oracle database.
Creating Java Stored Procedures
There are a few steps involved in turning a Java method into a Java stored procedure. These include loading the Java class into the database using the loadjava utility, and publishing the Java methods using a call specification (Call Spec) to map Java methods, parameter types, and return types to their SQL counterparts. The following section shows how to do this.
I'll use a simple Hello class, with one method, Hello.world(), that returns the string "Hello world":
public class Hello
public static String world ()
return "Hello world";
The Loadjava Utility
Loadjava is a utility for loading Java source files, Java class files, and Java resource files; verifying bytecodes; and deploying Java classes and JAR files into the database. It is invoked either from the command line or through the loadjava() method contained within the DBMS_JAVA class. To load our Hello.class example, type:
loadjava -user scott/tiger Hello.class
As of Oracle9i Release 2, loadjava allows you to automatically publish Java classes as stored procedures by creating the corresponding Call Specs for methods contained in the processed classes. Oracle provides Oracle9i JDeveloper for developing, testing, debugging, and deploying Java stored procedures.
The Resolver Spec
The JDK-based JVM looks for and resolves class references within the directories listed in the CLASSPATH. Because Oracle database classes live in the database schema, the OracleJVM uses a database resolver to look for and resolve class references through the schemas listed in the Resolver Spec. Unlike the CLASSPATH, which applies to all classes, the Resolver Spec is applied on a per-class basis. The default resolver looks for classes first in the schema in which the class is loaded and then for classes with public synonyms.
loadjava -resolve <myclass>
You may need to specify different resolvers, and you can force resolution to occur when you use loadjava, to determine at deployment time any problems that may occur later at runtime.
loadjava -resolve -resolver "((* SCOTT) (foo/bar/* OTHERS)
(* PUBLIC))"
Call Spec and Stored Procedures Invocation
To invoke a Java method from SQL (as well as from PL/SQL and JDBC), you must first publish the public static method through a Call Spec, which defines for SQL the arguments the method takes and the SQL types it returns.
In our example, we'll use SQL*Plus to connect to the database and define a top-level Call Spec for Hello.world():
SQL> connect scott/tiger
SQL> create or replace function helloworld return
VARCHAR2 as language java name 'Hello.world () return
java.lang.String';
Function created.
You can then invoke the Java stored procedure as shown below:
SQL> variable myString varchar2[20];
SQL> call helloworld() into :myString;
Call completed.
SQL> print myString;
MYSTRING
Hello world
Java stored procedures are callable, through their Call Spec, from SQL DML statements (INSERT, UPDATE, DELETE, SELECT, CALL, EXPLAIN PLAN, LOCK TABLE, and MERGE), PL/SQL blocks, subprograms, and packages, as well as database triggers. The beauty of Call Spec is that stored procedure implementations can change over time from PL/SQL to Java or vice versa, transparently to the requesters.
Call Spec abstracts the call interface from the implementation language (PL/SQL or Java) and therefore enables sharing business logic between legacy applications and newer Java/J2EE-based applications. At times, however, when invoking a database-resident Java class from a Java client, you may not want to go through the PL/SQL wrapper. In a future release, Oracle plans to provide a mechanism that will allow developers to bypass the Call Spec.
Advanced Data-Access Control
Java stored procedures can be used to control and restrict access to Oracle data by allowing users to manipulate the data only through stored procedures that execute under their invoker's privileges while denying access to the table itself. For example, you can disable updates during certain hours or give managers the ability to query salary data but not update it, or log all access and notify a security service.
Sharing Data Logic Between Legacy and J2EE Applications
Because legacy applications and J2EE applications both invoke stored procedures through the Call Spec, the same data logic can be shared between J2EE and non-J2EE worlds. Thanks to Call Spec, this data logic can be shared regardless of the implementation language used (whether PL/SQL or Java).
Autogeneration of Primary Keys for BMP Entity Beans
When using BMP for EJB entity beans, a bean instance can be uniquely identified by the auto-generated primary key associated with the newly inserted data as a return value for ejbCreate(). You can retrieve this value within ejbCreate() in one database operation by using a stored procedure that inserts the corresponding data and retrieves or computes the primary key. Alternatively, you could insert the data and retrieve the corresponding key (or ROWID) in one SQL statement, using the RETURN_GENERATED_KEYS feature in JDBC 3.0. However, the stored procedure approach is more portable across JDBC driver versions and databases.
You can implement this pattern with these three steps:
Create the Java stored procedure, defining a public static Java method insertAccount() within a public GenPK class. This method will insert data, compute a unique key (by passing out a sequence number), and return the computed key as primary key.
Define the Call Spec.
CREATE OR REPLACE PROCEDURE insertAccount(owner IN
varchar, bal IN number, newid OUT number)
AS LANGUAGE JAVA NAME 'GenPK.insertAccount(
java.lang.String [])';
Invoke the stored procedure within ejbCreate().
Public AccountPK ejbCreate(String ownerName, int balance) throws CreateException
try {
CallableStatement call = conn.prepareCall{
"{call insertAccount(?, ?, ?)}"};
return new AccountPK(accountID);
Custom Primary Key Finders for CMP Entity Beans
Finder methods are used for retrieving existing EJB entity bean instances. Primary key finders allow you to retrieve a uniquely identified EJB instance. For CMP entity beans, the EJB container automatically generates the primary key finder findByPrimaryKey() method, based on declarative description. In some situations, however, you might need more control; for example, you may need a specialized finder such as findByStoredProcKey(). In these situations, you can use Java stored procedures in conjunction with an object relational framework (such as Oracle9i Application Server [Oracle9iAS] TopLink) to implement a custom primary key finder method. After you define the EJB finder as a REDIRECT or NAMED finder, TopLink will generate the SQL query for retrieving the bean instance.
Data-Driven EJB Invocation
In a data-driven architecture, business logic invocation can be triggered as a result of database operations (such as inserts, updates, or deletes). A Java stored procedure implementing the data logic can be declared as a database trigger to invoke EJBs running in a middle-tier J2EE application server. You can make EJB calls by using either standard remote method invocation (RMI) over Interoperable Inter-ORB Protocol (IIOP), using a J2EE 1.3 compatible server, or RMI over a vendor-specific transport protocol (such as ORMI with Oracle9iAS/OC4J or RMI over T3 with BEA WebLogic). Each application server vendor has its own optimized protocol while providing RMI over IIOP for interoperability. Oracle9iAS supports both RMI calls over IIOP and ORMI protocols.
Data-Driven Messaging
Oracle9i Database embeds Advanced Queuing (AQ), which is an integrated, persistent, reliable, secure, scalable, and transactional message-queuing framework. Oracle exposes AQ features to Java developers through the standard Java Messaging System (JMS) API. Java stored procedures can invoke AQ operations through the JMS interface to allow fast, intra-session, scalable, data-driven messaging.
Java stored procedures can use JMS to invoke AQ operations. You can implement this pattern in four steps:
Create and start the JMS Queue (to do so, embed the following operations within a SQL script):
execute dbms_aqadm.create_queue_table(queue_table =>
'queue1', queue_payload_type =>
'SYS.AQ$_JMS_TEXT_MESSAGE', comment => 'a test queue',
multiple_consumers => false, compatible => '8.1.0');
execute dbms_aqadm.create_queue( queue_name => 'queue1',
queue_table => 'queue1' );
execute dbms_aqadm.start_queue(queue_name => 'queue1');
Create the Java stored procedure (a code snippet is shown):
public static void runTest(String msgBody)
try
// get database connection
ora_drv = new OracleDriver();
db_conn = ora_drv.defaultConnection();
// setup sender (cf online code sample)
// create message
s_msg = s_session.createTextMessage(msgBody);
// send message
sender.send(s_msg);
s_session.commit();
// receive message
r_msg = (TextMessage) receiver.receive();
r_session.commit();
// output message text
String body = r_msg.getText();
System.out.println("message was '"+body+"'");
Create the Call Spec:
create or replace procedure jmsproc (t1 IN VARCHAR)
as language java name 'jmsSample.main (java.lang.String[])';
Invoke the stored procedure:
call jmsproc('hello');
Database-Assisted Web Publishing (Cache Invalidation)
One of the common issues application architects must face is how to cache database information reliably to increase overall system performance. JCACHE is an upcoming standard specification (JSR 107) that addresses this problem. It specifies an approach for temporary, in-memory caching of Java objects, including object creation, shared access, spooling, invalidation, and consistency across JVMs. It can be used to cache read-mostly data such as product catalogs and price lists within JSP. Using JCACHE, most queries will have response times an order of magnitude faster because of cached data (in-house testing showed response times about 15 times faster).
In order to track all the changes to the origin data and refresh the cached data, a Java stored procedure is attached to a table as a trigger. Any change to this table will result in the automatic invocation of this stored procedure, which in turn will call out a defined JSP to invalidate the JCACHE object that maps its state to the database table. Upon invalidation, the very next query will force the cache to be refreshed from the database. Next Steps

Extending Database Functionality
One of the great things about running Java code directly in the database is the ability to implement new functionality by simply loading the code or library and using the Call Spec to make the entry points (public static methods) available to SQL, PL/SQL, Java, J2EE, and non-Java APIs. Oracle9i Database customers can easily extend database functionality. Oracle itself leverages this capability for new utilities and packages such as the XML Developer Kits (XDKs).
Bridging SQL, PL/SQL, Java, J2EE, .NET, and XML
The Oracle XDK is written in Java and exposes its public methods as Java stored procedures, extending the database's XML programmability. SQL, PL/SQL, Java, J2EE, and non-Java (.NET) business logic all have access to the XML parser, the XSLT processor, the XPath engine, and XML SQL Utility (XSU).
The XML parser is accessible through the xmlparser and xmldom packages. XSU is a Java utility that generates an XML document from SQL queries or a JDBC ResultSet, and writes data from an XML document into a database table or view. Using XSU, XML output can be produced as Text, DOM trees, or DTDs. XSU is exposed to PL/SQL through the dbms_xmlquery and dbms_xmlsave packages.
Conclusion
The integration of the Oracle database with a Java VM enables the creation of portable, powerful, database-independent data logic and persistence logic. The loose coupling of business logic that runs in the middle tier with data logic that runs in the database tier improves application scalability, performance, flexibility, and maintenance.

Launching Rescue & Recovery from a Command Line

Question - I would like to know how I can launch Rescue & Recovery from a command line.
Issue that is prompting the question - My laptop was sitting in my computer bag overnight. The battery was fully charged. I BELIEVE that it was in suspend mode at the time. When I opened it in the morning, there was a message on the screen saying that a backup had not completed successfully. I then noticed that the battery had run down completely.
My Plan - I would like to launch Rescue & Recovery (as well as the Defrag utility) from Windows Task Scheduler. If I do, then all schedule tasks will be launched and controlled using the same process. Windows Task Scheduler also provides two key scheduling criteria that the IBM Rescue & Recoverry or the IBM Maintenance Manager utilities do not provide -
#1 - Run this task only when the PC is on AC power.
#2 - Run this task ony when the computer is idle (so that it doesn't slow down the PC if I happen to be working on it)
Background Concerns -
- Having a backup job automatically start when the computer is in my computer bag will run down my battery when I least expect it.
- The PC may could also be damaged due to overheating, since the sides of the computer bag block the ventilation holes.
Additional Info
- If I go to the ThinkVantage Productivity Center and select the Quick Link for "Backup Now" this will indeed launch a backup on demand. I assume that selecting this option is calling a specific executable file.
- However, the only two applicable executable files that I see in the C:\Program Files\Lenovo\Rescue and Recovery directory are "mr_gui.exe" and "wizrr.exe". Both of these files launch an interface that requires the user to make a selection. As a result, it doesn't look as if either of these files would work for unattended operation, unless there is some sort of switch that I can put in that will automatically start the backup process.
- I called the support line (only once so far), but that particular rep did not know of any way to launch Rescue & Recovery other than from the standard R&R user interfaces.
Any help is greatly appreciated,
Mathew

The correct way to invoke a JSP is to make a request to the Server.
Normally you would use your browser to do this.
On a unix system, you can use the wget command to invoke a url without using a browser.

Lenovo N200 and Recovery from CD

Hello !
Im new here and english is not my language so plz forgive me any mistakes or putting topic in wrong place.
I have problem with doing Recovery on Lenovo N200. Problem is when i do recovery from CD, i can't turn off some useless apps for me. I don't want to install Symantec's and Office tryouts and staff from Lenovo. I'd like to get clear Windows. However, i can turn off these apps. I CAN turn off apps when doing recovery from hidden partition.
But that model im working with has hidden partition delated. What to do? Uninstalling that software after is rather not good way to keep Windows clean.
Message Edited by Kreton on 09-23-2008 10:37 AM

It sounds as though you're on the way to recovering your system
When it's finished, I suggest you install ThinkVantage System Update to get your drivers up to date, you'll need .NET framework as explained on the site.
Just in case info. - If, as somtimes happens, it can't install because a previous version of IBM's Software Installer is installed which it can't seem to uninstall, and which also doesn't appear in Control Panel > Software, go to C:\IBMTOOLS\APPS\UPDATER and run the setup.exe this will give you the option to uninstall.

Cannot force destructive system recovery from recovery disc set Pavilion a1630n

I have a Pavilion a1630n. This desktop originally came with windows xp media center edition 2005.
I had exercised the windows vista home premium express upgrade several/many years ago.
I attempted to restore the computer after getting malware or virus infected.   I found that microsoft system restore had been turned off and no system restore points were available.   The set of vista system recovery discs that I had made after the os upgrade were also seemingly unuseable. I attempted to perform a destructive system recovery from the external discs that I had purchased in 2009. The recovery seemed to take place from the hard drive only and did not request recovery disc 2 or 3.
I now have a windows xp operating system with no files in the hp recovery partition except hidden files.  An attempt to run another recovery returns a message that the recovery partition not found! no software is available for reinstallation. hardware tests that I have run show no problems with any hardware.
I've attempted to various combinations of restarts per the support documents wither using the f10 or esc key to no avail.
Ideally I would like to know that the hard drive was successfully formatted and that the recovery takes place from the system recovery discs that I had purchased. (I'm fairly sure that the discs worked at one point as I used them prior to the windows vista upgrade.)   I believe that the discs are still in good condition as I can browse the discs on the laptop that I am using. I've also written and read cd's successfully but I have not attempted to read or write a dvd format.

At power on the menu options listed are
esc Boot Menu
F1 setup
F10 Recovery
I tried f9 per your suggestion since this is not a defined key. I can see the optical drive access the disk with the blinking cursor....after a minute or two the computer boots from the hard drive and does NOT attempt to perform system recovery.
I have set the to boot from the optical drive first (tsst corp ts-h652m)
The optical drive is accessed but eventually (after a minute or two) the computer boots up from the hard drive.
If I change the bios settings to only boot from the optical drive after a few minutes I receive the following message
" Disk boot failure, Insert system disk and press enter"
FYI
drivers in use
Samsung SP2504C (HDD) uses 5.1.2535.0
Tsst TS-h652m (optical drive) uses 5.1.2535.0
phoenix bios rev 3.10 12/13/2006
core rev 6.0
Any other suggestions ?

Missing partitions after running Recovery from previous System Image Backup in Windows 8.1

After running Recovery from a recent Sytem Image Backup the LRS_ESP partition is now missing and the Used space on the PBR_DRV partition is reported as 95.20MB while it previously reported 9.52GB in use. The WINRE_DRV, SYSTEM_DRV, Windows8_OS and D:LENOVO partions appear to be OK.
I ran the Recover after replacing the original 500GB HDD with a 1TB. Any details/links/recommendations on recreating/correcting the LRS_ESP and PBR_DRV partitions? Thanks!

Where can I buy a larger hard drive for my late 2008, 15" macbook pro? From reviewing questions and answers on the support community it would appear that having Apple remove the old and install the new hard drive is recommended. But how/where?

Where can I buy a larger hard drive for my late 2008, 15" macbook pro? From reviewing questions and answers on the support community it would appear that having Apple remove the old and install the new hard drive is recommended. But how/where?

Welcome to Apple Support Communities
You can install the new hard disk yourself if you want to. You just need a 2'5" SATA II hard drive, which is compatible with your MacBook Pro. You can buy one at OWC > http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/ You can filter hard drives by computer, so press a "Click to view all...", choose your computer in the sidebar and it will give you the compatible hard drives.
There are different brands for the MacBook Pro. The most recommended are HGST and Seagate, which have good reputation. A 7200 rpm hard drive will give you extra performance

Windows Server 2012 - Backup failing with Exchange - The application will not be available for recovery from this backup. the consistency check failed

Hi
We have a Windows 2012 server with Exchange 2013, all is working fine except now i am getting issues with the backup.
'Exchange - The application will not be available for recovery from this backup. the consistency check failed for the component Microsoft Exchange Server'
I have checked the database all is fine, i have created a new db and move all mailbox;s over and then removed the old db, i have enabled circular logging and then disabled it, it seems no matter what i do i cannot get a full backup!
i did have to restore the server once and the backups still worked for about 4 days after that and then stopped, i have also tried to remove and re add the backup role!
i am stumped, any advice would be great!

Hi
Ok, i created a test db and tried to back it up right away, it failed, i did not add any mailbox's to it either. i got quite a few events in the windows logs, as well as the same event above i got the following:

Time Machine Full Recovery From Wireless Backup

I am reporting this as a learning experience for all.
I just had a hard drive fail on my MacBook. Apple Care was golden and now I have a clean install with Leopard.
Here is my situation. MacBook backed up via time machine on a wireless network. Windows on boot camp partition. Dedicated disk (1TB Buffalo) connected to wife's iMac via firewire.
I want to do a full recovery. I start up leopard and it gives me the option to do a full recovery during setup. I have no time machine backup list provided. I continue with setup. When I go to the recover option of time machine I am asked to select a file. This is when I call tech support.
Tech Support says I should have had the backup disk connected directly via firewire for setup to see it. Time machine stores the backup under these conditions as a Sparse bundle. Now that I am past setup I have to do a migration rather than a recovery. I start up the migration assistant and I still cannot access the sparse bundle as it is grayed out. The leap here is you have to mount the sparse bundle, double click, then it shows up as a disk you can migrate from.
Windows Partition, as TS puts it is "on its own".
The confusion for me was that I could not recover exactly as I had backed up.
I hope this helps someone. Cheers!

It seems to be. All music, photos, applications, etc. are present. I have not had time to do a complete review of my migration, I will track this post for a while and report any problems. There were significant OS updates which were required. I thought that they would be included as part of the migrate, not so. Perhaps they are on a true "full recovery" from setup, any one know?
Migration has no option for any part of the OS. It assumes you already have it.
If you recover your entire system from a TM backup (assuming nothing significant was excluded), you get your entire system back exactly the way it was: the OS, Apps, settings, preferences, user data, etc.
You don't load a new OS from the Leopard Install disc -- you only use it for it's copy of Disk Utility and the installer -- everything else comes from your TM backup.

OneKey Recovery from External drive

Hello,
I am trying to restore my system with Onekey Recovery from an external drive. However, onekey recovery onlys shows two path for selecting images - C drive and E drive.
When I select the E drive, it is not pointing to my external drive. How do I change the configuration such that Onekey can access my external drive to find the backedup image ?
Thanks,
Kim

Hi @Karlo12333 ,
Welcome to the HP Forums!

Unfortunately coping the partition does not work. I don't thing you will be able to create recovery media from the copied partition on the external but if you have not yet created recovery disk you can give it a try.
If you cannot create the recovery media you will need to contact HP support to obtain a recovery kit.
Please call our technical support at 800 474 6836. If you live outside the US/Canada Region, please click the link below to get a support number for your region.

Recovery from USB media fails in error 10-fc12-0241

-Got a new laptop t135-s1309.
-works great.
-created recovery media on usb using the creation utility.
-to test recovery media, I ran recovery from the usb media.
-starts and carry's out recovery for a time.
-then error 10-fc12-0241 is displayed.
-I then recovery from the hidden partition on the hard disk by holding the zero key down during startup.
-this works and the machine is restored.
-by the way i shrunk the 'c' drive to 70 Gb and have a 210 Gb 'd' drive.
-the machine recovers as expected from the hard drive. I use the choice where partitions are not altered.
-I tried two different usb flash drives. One a Kingston 8GB, the other a Dane-Elec 8GB.
-I don't feel there is a hardware problem.
-I want to have recovery media besides the hard drive so I can recover should the hard disk fail or the hidden partition becomes faulty/unusable.

Probably because the recovery program doesn't support USB connected devices.

Recovery from D:

I want to format my C drive. If I run recovery from the partitioned D drive will this be accomplished.
Thanks

Hi,
Yes, if you perform a recovery using the Recovery Partition D, this will perform a quick format of the Hard Drive. However, if you have data you wish to ensure is unrecoverable, you may want to consider a disk wiping utility. I would always recommend making sure that you have created your set of Recovery Discs before using any wiping utility just in case the Recovery Partition is accidentally wiped as well.

DP-K
