About database backup
I install oracle 8.0.5ee on my redhat 6.2. HOw can I realize hot backup and hot recover on line.
Hi,
If you want another backup process to truncate the logs instead of DPM, you can just configure DPM to synchronize
just before a recovery point. That basically tells DPM to just perform express full backups which will not truncate logs.

Newbie questions about Database replication, "backups", and sql version
Just created my first Sql Database using the "SQL Database Management Portal". A blast but three questions come to mind:
1. Is this DB automatically
"replicated"? (In other words, is DB "failover" or clustering, a feature of all newly created Azure databases?)
2. Our on-premise model is to make a daily DB backup which is saved to a nightly tape. If needed, we can restore a two-month old database backup under a new name to compare it with the current one. Does Sql Azure support this capability
or not? Can it be requested?
3. Which on-premise version of sql is "Sql Azure" closest to? (2014?)
TIA,
edm2
P.S. My database was created using the "web" edition.Hi edm,
According to your description, you create a SQL Azure database in Azure platform. The replication feature is not supported by Microsoft Azure SQL database. If you want to sync the SQL Azure database and local database, you can use SQL Azure Data Sync service.
For more information, see:
http://blogs.technet.com/b/the_cloud_pilot/archive/2011/10/24/your-first-sql-azure-data-sync-step-by-step.aspx
In addition, if you have Web or Business Edition databases, you must create your own backup strategy. You can use database copy or Import and Export services to create copies of the data and export the file to an Microsoft Azure storage account. Meanwile,
Windows Azure SQL Database provides a mechanism for automating the process for exporting a database to BACPAC files on a set interval and frequency. For more information, see:
Schedule an Automated Export:

Windows Azure SQL Database Backup and Restore strategy:
http://www.mssqltips.com/sqlservertip/3057/windows-azure-sql-database-backup-and-restore-strategy/
Currently, Azure uses a special version of Microsoft SQL Server as its backend. It provides high availability by storing multiple copies of databases, elastic scale and rapid provisioning, when we check the version of SQL Server, it shows as follows.
Microsoft SQL Azure (RTM) - 11.0.9216.62

Doubt about database point in time recovery using rman
Hi Everyone,
I have been practising various rman restore and recovery scenarios . I have a doubt regarding database point in time recovery using rman. Imagine i have a full database backup including controlfile scheduled to run at 10 PM everyday. today is 20th dec 2013. imagine i want to restore the database to a prior point in time ( say 18th dec till 8 AM). so i would restore all the datafiles from 17th night's backup and apply archives till 8 AM of 18th dec . in this scenario should i restore the controlfile too from 17th dec bkp ( i am assuming yes we should ) or can we use the current controlfile ( assuming it is intact). i found the below from oracle docs.
Performing Point-in-Time Recovery with a Current Control File
The database must be closed to perform database point-in-time recovery. If you are recovering to a time, then you should set the time format environment variables before invoking RMAN. The following are sample Globalization Support settings:
NLS_LANG = american_america.us7ascii
NLS_DATE_FORMAT="Mon DD YYYY HH24:MI:SS"
To recover the database until a specified time, SCN, or log sequence number:
After connecting to the target database and, optionally, the recovery catalog database, ensure that the database is mounted. If the database is open, shut it down and then mount it:
2. SHUTDOWN IMMEDIATE;
3. STARTUP MOUNT;
4.
Determine the time, SCN, or log sequence that should end recovery. For example, if you discover that a user accidentally dropped a tablespace at 9:02 a.m., then you can recover to 9 a.m.--just before the drop occurred. You will lose all changes to the database made after that time.
You can also examine the alert.log to find the SCN of an event and recover to a prior SCN. Alternatively, you can determine the log sequence number that contains the recovery termination SCN, and then recover through that log. For example, query V$LOG_HISTORY to view the logs that you have archived.
RECID STAMP THREAD# SEQUENCE# FIRST_CHAN FIRST_TIM NEXT_CHANG
1 344890611 1 1 20037 24-SEP-02 20043
2 344890615 1 2 20043 24-SEP-02 20045
3 344890618 1 3 20045 24-SEP-02 20046
Perform the following operations within a RUN command:
Set the end recovery time, SCN, or log sequence. If specifying a time, then use the date format specified in the NLS_LANG and NLS_DATE_FORMAT environment variables.
If automatic channels are not configured, then manually allocate one or more channels.
Restore and recover the database.
The following example performs an incomplete recovery until November 15 at 9 a.m.
RUN
SET UNTIL TIME 'Nov 15 2002 09:00:00';
# SET UNTIL SCN 1000; # alternatively, specify SCN
# SET UNTIL SEQUENCE 9923; # alternatively, specify log sequence number
RESTORE DATABASE;
RECOVER DATABASE;
If recovery was successful, then open the database and reset the online logs:
5. ALTER DATABASE OPEN RESETLOGS;
I did not quiet understand why the above scenario is using current controlfile as the checkpoint scn in the current controlfile and the checkpoint scn in the datafile headers do not match after the restore and recovery. Thanks in Advance for your help.
Thanks
satyaThanks for the reply ... but what about the checkpoint scn in the controlfile . my understanding is that unless the checkpoint scn in the controlfile and datafiles do not match the database will not open. so assuming the checkpoint scn in my current controlfile is 1500 and i want to recover my database till scn 1200. so the scn in the datafiles (which is 1200) is not not matching with the scn in the controlfile(1500). so will the database open in such cases.
Thanks

Daily database backup runnig on RAC 10.2.0.3 with two Solaris nodes & ASM
Hello,
I'm confused about making daily incremental RMAN backup of a database runnig on Oracle RAC 10.2.0.3 on two Solaris nodes and ASM.
Databases cannot be stopped for backup and point in time recovery is needed.
Please correct me if I am doing wrong:
1) Backup must be Weekly database Level 0 and Daily database Level 1 is appropriate.
2) Is best to use a Flash Recovery Area (FRA) - I've setup one on a separate ASM volume. I have enough space to do the backup on FRA.
3) I am confused about the number channels I need to use. Do I need to use separate RMAN backup channels for each node or I can just leave the default:
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
4) Below are the RMAN scripts I plan to use for
- Weekly database backup Level 0:
#!/usr/bin/ksh
echo BACKUP FULL: $ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup incremental level 0 database TAG bkp_level0_200906010;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
- Daily database backup Level 1:
#!/usr/bin/ksh
echo BACKUP INCREMENTAL: $ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup incremental level 1 database TAG bkp_level1_20090611;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
I'm I doing things wrong?Show also the parameter I have set for RMAN:

Hi people,
I´ve the next doubt about the backups of MS SQL Server.
If I make a full database backup, the transaction log (SIDLOG1) are backed? Or I´ve to do the backup of transactional log separated?
In the note Note 44449 - Backup strategies with the SQL server, says this:
"If you run a complete database backup, the contents of the transaction log are saved (database dump), but the log is not shortened. The transaction log is only shortened when you save the log (transaction dump)."A FULL SQL backup includes all of the changes that are contained in the LOG file, so that the backup is recoverable to any point in time from the beginning to the end of the time it takes to backup the database. However, it does NOT truncate the log file because you may still need a log backup in order to be recoverable to a point in time AFTER the FULL backup mentioned earlier, or if you have to utilize a different FULL backup in the event the other backup is corrupted, lost, etc.
For example:
Full backup A taken 11/8/2010, begin 8:00 AM, completed 9:00 AM.
Transaction Log backup 1 taken 11/8/2010, 11:00 AM
Transaction Log backup 2 taken 11/8/2010, 3:00 PM
Transaction Log backup 3 taken 11/8/2010, 7:00 PM
Full backup B taken 11/9/2010, begin 8:00 AM, completed 9:00 AM.
Transaction Log backup 4 taken 11/9/2010, 11:00 AM
Transaction Log backup 5 taken 11/9/2010, 3:00 PM
Transaction Log backup 6 taken 11/9/2010, 7:00 PM
If you need to recover to point in time 11/9/2010 at 8:30 AM, all you need is Full backup B.
If you need to recover to point in time 11/9/2010 at 5:00 PM, you need Full backup B, and Transaction Logs 4, 5, and 6.
If you need to recover to point in time 11/9/2010 at 5:00 PM, and Full backup B is corrupted, you need Full backup A, and Transaction Logs 1, 2, 3, 4, 5, and 6.
If Full backup B had truncated the log, then you would not be recoverable to any point in time after 7:00 PM on 11/8/2010. -
SQL Server 2008 & 2012 Database backup on a shared loaction

I have to plan for the Database backup on SQL Server 2008 & 2012 on a shared Path.
We are building a new Maintenance plan & specify the Database which needs to be backup & at the Folder location we specify the Shared Path Location. These steps I have followed using the below link,

Purvish ShahHello,
>>'\\DBBackup\SharePoint_backup\DB_backup_2014_02_13_122719_5314660.bak'. Operating system error 5(Access is denied.).
This clearly points out to fact that your SQL Server service account does not have permission of read/write on shared location,simple.
>>But when I open the shared path in the Windows Explorer it opens successfully.
This is because when you are browsing through explorer your windows login credential is used to access that folder but when you are running backup your SQL Server service account permission is used to write backup on shared folder ( which I assume it does
not have ) so the access denied error.
Hope this helps
PS: I reffered the link its maily how you specify backup path its not about access denied error due to SQL server service acount not having privilege

Database backup restore problem
This question was asked in Setember but was not answered and is now archived.
I'm using final cut server 1.1.1 on snow leopard Server.
i can not restore my backup file(XXXXXX.zip)
below is the error display....

Restore failed: unzip exited with code 81. <---- what is code 81 ????
what's the problem ????? anyone help me...
I have substituted XXXXX for the name of my backup file
I really need some help here. My database was lost and I need to restore the backup. We have a lot of hours of cataloguing and metatagging in there!
thanksHello Everyone,
I haven't solved the problem, but I have found the root of it. The short answer is DO NOT RUN FINAL CUT SERVER 1.1.1 ON A MACHINE WITH SNOW LEOPARD SERVER!!!
I finally realized through a long and painful process of trying to restore our database, rolling back to Leopard server, upgrading again to Snow Leopard Server, and going back again to Leopard Server, that ALL of our database backups created after the Snow Leopard Server upgrade cannot be restored in FCServer 1.1.1. I don't know if FCServer 1.5 will read them, and I'm not about to spend the money to find out.
I'm really disappointed here. Apple does say that FCServer 1.5 is the compatible version to run with Snow Leopard server, but they certainly don't warn of the disaster that could occur if you try to run FCserver 1.1.1 with Snow Leopard Server.
Right now I'm trying to figure out how to extract the data from hundreds of items that have been entered so that we don't have to re-enter them all again.
So again, be warned. If you are upgrading to Snow Leopard Server, upgrade your FCServer too. At least I hope that's all it takes. For our part, we're back to Leopard Server and staying there for a while.

Dear Friends,
Let my production server running starts from 1st June .
In 15 june , I take the First rman full (or level0) backup using the command :
RMAN> backup database plus archivelog;
In 20 June I take 2nd rman full backup using : RMAN> backup database plus archivelog;
Again in 30 June , I take the Third(3rd) rman full (or level 0) backup using the command :
RMAN> backup database plus archivelog;
And also my rman policy set as :
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;
In the above scenario , I have the following questions :
1) When I take the Third(3rd) backup then is it the First RMAN backup goes to obsolete as per my rman policy ( RETENTION POLICY TO REDUNDANCY 1) ?
2) Is the above all RMAN backup make a link between them ?
3) If my first RMAN backup goes to obsolete and I have to delete the First RMAN backup , then which types of problem I face ? Can I go to previous state(suppose I need to back in 1st June) of my server if I delete First rman backup ?
4) when I take 3rd rman full backup , then is it all information from 1st january of the server are stored in the 3rd backup ? i.e., is the 3rd rman backup stores all the previous two rman backups information ?so that If I delete the previous two backup , then I get all information form 3rd rman backup .what is the actual scenario ......
plz help me to make clear concept about it .......
thx in advance .....1) When I take the Third(3rd) backup then is it the First RMAN backup goes to obsolete as per my rman policy ( RETENTION POLICY TO REDUNDANCY 1) ?The REDUNDANCY parameter of the CONFIGURE RETENTION POLICY command specifies how many backups of each datafile and control file that RMAN should keep. In other words, if the number of backups for a specific datafile or control file exceeds the REDUNDANCY setting, then RMAN considers the extra backups as obsolete.So as in your case the redundancy is 1 so the 1st and 2nd backup are obsolete.
To check the obsolete backups run
rman> report obsolete;
To delete them
rman> delete obsolete;
Link:[http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/setup005.htm#BRBSC400]
Is the above all RMAN backup make a link between them ?I am not very much clear with the question.The RMAN information is stored in the controlfile.You can also create a new recovery catalog and register the target database. The RMAN repository records in the control file will be copied to the new recovery catalog.
when I take 3rd rman full backup , then is it all information from 1st january of the server are stored in the 3rd backup ? i.e., is the 3rd rman backup stores all the previous two rman backups information ?so that If I delete the previous two backup , then I get all information form 3rd rman backupThe 3rd RMAN backup will contain all the information of the DB from the very 1st day.You will get all the information in the 3rd rman backup as its a level 0 or what we say a FULL DATABASE BACKUP.If suppose the 3rd rman backup would have been a incremental backup, then you would have required a full backup, previous to the incremental one, so that after restoring the full backup, you restore the incremental to recover the DB completely.

[http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup004.htm#BRBSC133]
Forgot to answer the 3rd question
3) If my first RMAN backup goes to obsolete and I have to delete the First RMAN backup , then which types of problem I face ? Can I go to previous state(suppose I need to back in 1st June) of my server if I delete First rman backup ?well, i am not very much sure , but i think is , if you have the 1st rman backup pieces physically present on the disk, you can catalog it and then use the rman command to restore the data from it of till 1st june.
To catalog the backup pieces use
rman> catalog backuppiece 'filename';

Hi All,
I Want to take Backup of my Schema (Using EXP ,Logical backup?) .i want only 10 Rows data for each table in my new schema.
Can anyone tell how to do that .
Thanks in Advance..What is the business purpose of trying to backup 1% of the data?
If you care about the data, you would be doing a full physical database backup to protect all the data. Or you would at least be exporting all the data in particular tables to protect against human errors (i.e. deleting all the data in a table in production rather than development accidentally).
If you don't care about the data, and you are just interested in the schema definition, you should be ignoring the data.
I cannot imagine a backup and recovery scenario where having 1% of the data in your backup would be useful. If you are trying to create a smaller version of your production environment for development (i.e. you are not treating this as a backup, but an extract), there are commercial tools out there that can generate relationally consistent extracts of a few percent of the data in your database-- those would be far preferrable to trying to build your own via export.

Database backup strategy(MS sql server 2005, Winodws 2003, SAP ECC 6.00)
Hello gurus,
I am confused, about the backup system i should go for(backup device, abckup software)?? Fllowing is my SAP Landscape.

3) Development

<b> I want to implemente before go live, backup system in my company.</b>
We have received backup schedule from our implementation partner. Our backup system is as follows.
Backup device is HP Surestore Autoloader.
Cartridge capacity is 100/200GB
Backup software is Veritas (version 8.6)
Note: Through this we take backup of our legacy system and it takes around 3 1/2 hour to 4 hours to take backup of 60 GB of our legacy data.
Right now the problem is our backup software version is old and i even believe, the hardware we have is not sufficient to take daily database backup and fortnightly, SAP system backup.
The only solution to the problem i can see is
1) to go for another backup device exclusively for SAP system
2) Even go for SQL Agent software used to take backup of SAP system thorugh Veritas.
3) Even upgrade my Veritas version.
<b> Its a request to GURUS</b>
1) Is the solution, i am thinking to this issue is correct.?? If no then please advice me
2) Please tell me the best backup system in your opinion for my above mentioned system.
Thanks Gurus
RahulHello,
A indication of the size of each database would be helpful.
However, its NOT a good idea to take only one on line backup a week. What if you have a tape error and cant recover a TL? You have no chance for recovery. This is not best practice. Can the business except a 4,5 or even 6 days loss of data - id guess not.
This is what id do if you don't want to purchase a new device, I would take an online backups from SQL to disk every night - this would be a separate disk! From the disk you can the pick up the backup to take at a time to suit that wont impact the existing backup. Plus you always have two copies of the backup. One on disk, one on tape.
My normal transaction log strategy is similar, again backup to disk, every hour on a production system. Then after midnight move the existing 24 logs into an archive folder. This folder would also be picked up by the existing device at a suitable time before being moved to a 'saved' folder and deleted the next day. Again you always have multiple copies of the data. two on disk, two on tape. -

Database backup file size is too small compare to actual database size
Hi All,
I know that backup file size can be smaller than actual DB size (i.e., MDF size + LDF size). But in my case i am observing huge difference.
My Database size is 16 GB out of which 10 GB consumed by MDF and 6 GB consumed by LDF. But when i took the backup, the backup file size is only 1 GB!!!!!
I am skeptical about whether i am doing anything wrong. Please advice me.Olaf is right it must be compressed backup:
To check if the backup file is compressed or not
RESTORE HEADERONLY FROM DISK = 'Path to backup file';
Looks for column labelled "Compressed". 1 = compressed, 0 = not compressed.
If you are skeptical about backup file you can verfiy whether a SQL database backup can be read and restored:
RESTORE VERIFYONLY FROM DISK = 'Path to backup file'
If the backup is valid, the SQL Server Database Engine returns:
The backup set on file 1 is valid -

I have a SQL 2008 R2 database that I am trying to move to 2012. Made a full backup of the database in 2008 R2. Recovery model is Simple, compatibility level is 2008 Went to 2012, created a dummy database, did Tasks--> Restore -->
Database , located the backup file, selected it, changed the file locations and tried to restore the backup (with overwrite option), got the following error:
BACKUP LOG cannot be performed because there is no current database backup.
This is a simple task that has always worked in 2008 R2. Does anyone know what the problem is and a possible solution?
ThanksHi,
This error occurs when the database recovery model has been changed to Simple and/or the recovery model has been changed back to Full but a full backup has not been performed since the change.
If a full backup has been performed, the following conditions will require that another full backup be taken:
· The recovery model had been changed without taking a full backup
· A SQL maintenance plan task had changed the recovery model (reindexing can cause this)
· A backup specifying TRUNCATE_ONLY had been run on the database
· The database was detached from another server and attached to the current server
Additionally, if we take full database backup after the Database is set to readonly, Then transaction log backup we will end up with this error. This is expected behavior. I have list an example within the link below.
Please check above conditions and fix your issue, if you have any concern, please let me know.
Example:
BACKUP LOG cannot be performed because there is no current database backup.

Is Adobe Flash 10.1 the "Culprit!" to "Slowness" and "Hangs?"
I just tried removing the "FlashPlayer" plug-in from HD > Library > internet plug-ins. Then restarted Safari 5 and it seems to be flying, no delays whatsoever? Don't know if the same result will be achieved on Intel's though.
