FIRST TIMER: Backups and recovery. [W530]
First time ever attempting to create recovery media, so the questions may be numerous.
For the first time creating backup media for Factory Recovery image, how much space is required on the medium?
I would prefer to have it stored onto a USB stick because they are much easier to store and keep track of...
Also, If i wanted to switch from the 500gb HDD that I ordered with the thinkpad to a SSD in the future would running the Factory Recovery media onto that drive create an exact image compared to the one on the HDD (included with preloaded partition "Q: Lenovo_Recovery") If not, how would I go about transfering the data?
W530 i7-3840Qm. Quad K1000M. 16GB RAM. 16GB mSSD(expresscache). 500gb HDD
The Backup program copies the data in your Windows partition to another drive, so you need as much free space in your backup drive as you have used space in your Windows partition. It also takes a correspondingly long time to complete, so keep that in mind.
In order to make an exact copy of the whole drive, you need imaging software like Acronis True Image, Norton Ghost, or something similar.
Thinkpad W530, i7-3720QM, 1920x1080 screen, 32GB RAM, dual SSDs (Samsung 830, Crucial M4 mSATA), Quadro K2000M, 9-cell battery, DVD burner, backlit keyboard, Bluetooth, Intel 6300 wireless card

Dell Backup and Recovery - Factory Recovery fails, need advice.
Back story:
I have tried this three times on three separate laptops, with poor results. Windows 7 on two of them and 8.1 one one, on all three the recovery partition is corrupt.I first boot it off of a live disk and backup any desired files. Then I boot, press F8, choose "Repair your computer" and discover that "Dell Factory Image Restore" is not one of the available options... so I boot the pc off of a different live disk and remove a bunch of "viruses", then I boot it off of the internal harddrive.In Windows I find that "Dell Backup and Recovery" may or may not be on the pc. It may or may not have ever been run before. If it is absent I download it and install it. When I run DBaR it tells me it needs to update, don't power off or disconnect the machine from the internet, etc. I then wait HOURS for this part to complete. When done it...

Hi,
I am a newbie in Oracle database 11g Release 11.2.0.1.0 and Oracle Linux and I have questions regarding backup and recovery.
I used the “Schedule Oracle-Suggested Backup” and have it run nightly to back up to local disk. In the Backup Setting, on the Retention Policy, I selected “Retain backup that are necessary for a recovery to any time within the specified number of days (point-in-time recovery) day = 7”
With the setting above, I checked the “Manage Current Backups” and I have many back sets for SPfiles, controlfiles, datafiles, and archivelogs for the last several days. However, for image copies, I have only one set and it get over write nightly. With the configuration above, is that true that I can only recover to any point in last 24 hours?
My goal is to be able to recover any “point-in-time” in the past 5 days, should I change my Retention Policy to “Retain at least the specified number of full backups for each datafile” to 5 backups (each full daily backup)? Please provide some advices. ThanksBy looking the following, it looks like by default its 24 hours but it depends upon the recovery window you choose.
Enterprise Manager makes it easy to set up an Oracle-suggested backup strategy for backups to disk that protects your data and provides efficient recoverability to any point in the a recovery window of your choosing. (In the simplest case, examined in this section, this window is 24 hours.) The Oracle-suggested strategy leverages Oracle's incremental backup and incrementally-updated backup features to provide faster backups than whole database backups, and faster recoverability than is possible through applying database changes from the archived log to your datafiles.
The Oracle-suggested backup strategy is based on creating an image copy of your database. This copy is rolled forward by means of incrementally updated backups. Oracle Enterprise Manager schedules RMAN backups jobs for you to run during the overnight hours.
For each datafile, the strategy calls for backups as follows:
At the beginning of day 1 of the strategy (the time the first scheduled job actually runs), an incremental level 0 datafile copy backup. It contains the datafile's contents at the beginning of day 1. In a restore-and-recovery scenario, the redo logs from day 1 can be used to recover to any point during day 1.
At the beginning of day 2, an incremental level 1 backup is created, containing the blocks changed during day 1. In a restore-and-recovery scenario, this incremental level 1 can be applied to quickly roll forward the level 0 backup to the beginning of day 2, and redo logs can be used to recover to any point during day 2.
At the beginning of each day n for days 3 and onwards, the level 1 backup from the beginning of day n-1 is applied to the level 0 backup. This brings the datafile copy to its state at the beginning of day n-1. Then, a new level 1 is created, containing the blocks changed during day n-1. In a restore-and-recovery scenario, this incremental level 1 can be applied to the datafile rolled forward on day n-1 to the beginning of day n, and redo logs can be used to recover the database to any point during day n.
The datafile copies used in the Oracle-suggested backup strategy are tagged with the tag ORA$OEM_LEVEL_0. The level 1 incremental backups for use in this strategy are created for use with datafile copies that are so labelled. You can safely implement other backup strategies without concern for interference from the backups for the Oracle suggested strategy.
There are also Oracle-suggested strategies that use tape backups along with disk backups, but those are beyond the scope of this chapter. -
Backup And Recovery on 7.2.3
i need information on backup and recovery, please help me.(from begin)
i don't speak english, but don't worry, i read the english.
Thanks you.
Oscar Rojano. [email protected]i suggest you read the oracle backup and recovery manual sections, or take the course, as this is an extremely important topic.
a cold backup is done when the database is down. to do a cold backup, first shutdown the database. then backup all datafiles. then restart the database. you can use this type of backup if your business can tolerate the database being down for the time it takes to do the backup.
a hot backup is done when the database is up and running. the database must be running in archive log mode. then, a hot backup can be performed by putting tablespaces into backup mode, and then backing up the affected datafiles. whenever you do a hot backup, you must be sure to also back up all archive log files from the start of the backup through the end of the backup. if you must restore the backup, and you don't have the archive logs, your database will not start and you will not be able to get it back.
an export is a backup of selected tables. it is not a complete backup and should not be used if a fast, complete recovery of the entire database is required. it is good if a fast restore of a single table is something you need to do often. be aware of database consistency problems if you are restoring a single table that is updated frequently.
depending on your requirements, you will use one or more of the three backup solutions above.
i would recommend that you use the oracle RMAN (recovery manager) tool, in conjunction with an enterprise backup tool from HP, Veritas, or IBM, to be sure your backups are as complete and reliable as possible. -
Backup and Recovery of Enterprise
I've inherited an instance of Enterprise XI R2, and have discovered that it is a critical system, but is not being backed up. I'm new to this, please bear with me.
I found the backup and recovery guide (https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c09a069c-6a3f-2b10-3399-e0ed04d866f8), and it gives a good high level overview, but I need a little more info.
Questions:
1. The guide states that "The Central Management Server (CMS) and all job-processing and Performance Management servers should be stopped by an automated script." Is there a specific order that the servers need to be stopped and started in? Would anyone be willing to share their script?
2. I assume that when the servers are down, anything scheduled to run during that time will be lost. i.e., the server won't check for missed jobs caused by the stopped state once the it resumes, correct?
3. The only thing that I need to back up on the file system is the contents of FileStore (C:Program FilesBusiness ObjectsBusinessObjects Enterprise 11.5FileStore*.*), correct?
4. This looks like a vanilla install using MySql. Would anyone be willing to share their MySql backup scripts? Is there a default password for MySql? How can I determine this password? How many databases are there?
5. I plan to create a backup script that stops the servers, copies the FileStore path to a backup folder (using xcopy to preserve the archive attribute), have MySql generate a backup file to the same folder, and then start the servers. This folder will be written to tape nightly (fulls on weekends, incrementals during the week). Is there anything else that I might need to backup? Config files? Ini's?
Thanks!!!1. There is no specific order, but last to go down should be CMS and first to come up should be CMS.

Backup and Recovery procedures for production system
I am trying to decide and test a best backup/recovery approach for our DBXML database in the production environment. Right now I am trying to go through the documentation.
http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_txn/CXX/filemanagement.html
What is the best option among offline, hot and incremental backups?
I am thinking of implementing incremental backups.
What are the constraints in implementing incremental backups? Is there a detailed step by step example to do this?
Can I test the backup and recovery procedures by copying the db files and log files from Linux (production) environment to my local machine (Windows XP)? I see only one log.00000000xx file in production and staging environments. It is of same size 52428800 in all our environments (both production and staging) at this point of time.
What is __db.001 file? What is the significance of this file in backup and recovery procedures?
A detailed input with example is greatly appreciated.
Thanks in advancsRaghu,
A couple of points, up front:
1. the __db* files are the environment (cache, locks, various shared memory regions), and are not part of backup, other than the fact that you need to checkpoint or otherwise flush your cache to your database(s) for a full backup.
2. log files are not architecture-neutral. That is you can't use a log file created on linux and just use it safely on another hardware platform. It's OK to copy them around, but they can only be used on the same architecture that created them. Database files (containers) are entirely portable among hardware and operating system platforms.
I don't know of a step-by-step cookbook for backups. This is because of the variations among application needs. However, the procedures described on this page are pretty straightforward:
http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_txn/CXX/backuprestore.html
I'm not sure what you mean by "constraints" on incremental backups. The only constraint is that you need to have a full backup first, or you won't be able to recover properly. Based on what I said above, the other constraint is that you'll only be able to recover on a machine of the same architecture as the one that created the log files.
As for testing, you can certainly copy your database and log files to your Windows machine, treating Windows as an offline backup. If you want to test recovery, you need to copy the files back to Linux. You'll start seeing additional log files when your log data starts to exceed the configured log file size.
Let me know if you need more clarification,
Regards,
George -

Issue with backup and recovery of WLS
I have installed WLS 10.3.6 in my 64-bit Linux box, now I am trying to take backup my server. I have a web-application deployed to my WLS, the path to my war file was something like:
<home_dir>/install_files/myapp.war
Now to take backup I ran tar command on my current Linux box, now I copied the .tar files to my new Linux box and extracted it. When I am starting my weblogic server it is looking for the war file from the path <home_dir>/install/myapp.war which does not exist on my new machine. So I logged into Admin console of WLS on my new machine and trying to change the path for myapp.war by clikcing update button. But I am getting this error when I change the path:
weblogic.management.ManagementException: [Deployer:149007]New source location, '/u01/Oracle/install_files/myapp.war', cannot be deployed to configured application, 'myapp'. The application source is at '<home_dir>/myapp.war'. Changing the source location is not allowed for a previously attempted deployment. Try deploying without specifying the source.
Update operation failed - no deployments changed.
Please help me how to deploy my files. I'm expecting backup and recovery option should also take care of deployed files but it is not happening in my case, is that wrong?1. There is no specific order, but last to go down should be CMS and first to come up should be CMS.

<Note:104796.1>Hi Alok,
why there is a need for standby here? you mean to say standby db?
what i exactly need is , whether i will be making use of archivelogs which are all archived during that backup period (in mount stage) after some days, if i face any problem with the PRODUCTION Database.. -
About Backup and Recovery in a distribuited enviroment
Hi.
I've read that if you more that one DB (say 2) connected in a distribuited enviroment, all DBs must be recovered in case one of your DBs fails.
I'd like to clarify the folloiwng issues:
- It that 100% true, i mean isn't an exception to that rule?.
- What happens if one DB is in archive mode and the other is not?
- Why do i have to restore both DBs if there's one one in trouble?.
- Isn't there a way to tell recovery process that you don't want restore or apply the distributed data, since you know that data is already there (at least in the case of complete recovery)?
Thanks in advance ...!I couldn't find much info on the topic for 9i (you don't mention your version), but found this in the Backup and Recovery Concepts manuls:
"If the database is a member of a distributed database system, then all databases in the system should operate in the same archiving mode. Note the consequences and constraints contained in the following table.
Mode Constraint Consequence
ARCHIVELOG
Closed cleanly
Backups at each node can be performed autonomously, that is, individually and without time coordination.
NOARCHIVELOG
Closed cleanly
Consistent whole database backups must be performed at the same global time to plan for global distributed database recovery. For example, if a database in New York is backed up at midnight EST, the database in San Francisco should be backed up at 9 PM PST."
Therefore, I wouldn't recommend having one database in archivelog mode and the other not. As far as your last question is concerned, I'd say that Oracle won't try any recovery if there isn't a need for it (if the data is already there), but that could be tested to confirm. I think that you need to read carefully the RAC concepts manual, and try some backup/recovery scenarios hopefully on a test box.

Dell Inprision 2330 Backup and Recovery error message 0x4001100200001005
A week ago, there were problems with the computer Dell Inprision 2330, and I'm using a Dell Backup and Recovery to restore the disk C to the image stored on the dvd disks. 3 days ago the computer began to hang when windows starts. I decided again to restore the system with dvd, but this time got the error message 0x4001100200001005.
Tried to restore the image to another drive, but the error appears again.
Other recovery media then dvd-disks "dell backup and recovery" I don't have.
Please help.I was very disappointed with this buggy system recovery. After I got tired of trying to restore the system, I found a post "Download Windows 8.1 Retail and OEM.iso". Did everything according to instructions. Now the computer is running. Activation performed automatically.

Hi, oracle guru.
I have searched in google how to backup and recover to and from removable disk or hard disk (in separated folder) in oracle XE 10g, but I didn't found any.
I tried to use backup and recovery database given from oracle itself, and I analyze which file is added and modified. I do somekind of trial and error action. First, I backup my database and then I copy 2 files (I forgot the names, 1 is about 853 kb, and one is the backup file (about 500 mb)). And then I do some user deletion (I have several users) and then I backup and copy again to different folder from the previous one. Note that I am not using archive log: on.
Unfortunately, when I copy the previous backup (the one with complete users) to oracle folder, the restore database does work until, I guess starting database, it throws error saying that something error in SYSTEM.DBF, thus making my oracle doesn't work, even I canot go to database home page.
My question is that how to backup and recover database to and from removable disk or harddisk with different folder? Which files do I need to copy or should I add backup and recover script?
Thanks for the reply.Yes, as I already mentioned, previously (assumes) that I have database with several users (say 5 users). And I use backup database and restore database from oracle folder in start menu, and it works perfectly (assuming that I delete one user and then restore database).
However, I tried to copy the backup file (which I mentioned before, but I am not sure the files I am copying is backup file since I only analyzed it). So, I test it. First I backup, and I copy to separate folder. Next, I do some user deletion, and I do backup. Say, for example I want to use that backup file in another computer. I copy the files to oracle installation folder. One in product/database/ folder, and one in flash-recovery area. When I try to use restore database (in start menu), it works, until, I guess, starting database, and it throws error saying that error in SYSTEM.DBF.
So, my point is that, how do I backup my database so that the backup file can be in separated folder (for example in removable disk), thus I can also select backup file to be restored. -
Backup and Recovery Procedures for S&OP
Hi Team,
My customer is trying to evaluate S&OP and has the following quesitons around backup and recovery. If you have any info on this, can you pl. share with me?
What is the SLA on Cloud based system availability?
How often does the backup happen for Cloud based system?
When a system goes down and there is a recovery, how much data would be lost – i.e., what is the lapse time between backups?
Thank you

Backup and recovery a tablespace
Hi all,
I recently started reading about oracle backup and recovery concepts, and I needed to understand what is happening where we put a tablespace to a backup mode (alter tablespace tablespace_name begin backup) ?
thanks for helpThree things happen when you put a tablespace in hot backup mode:
1. A checkpoint is issued, so that dirty blocks belonging to that tablespace are flushed to disk
2. The header of the datafiles associated with the tablespace are locked from further update by CKPT.
3. The first insert/update/delete that affects a data block that is part of the tablespace being backed up, after the 'begin backup' command is issued, causes the entire block to be written to the online redo logs. Second and subsequent changes generate the same amount as redo as normal, though.
That's it. As Hemant mentions, the really important bit is number 2 in that list: whilst the header of the datafile(s) is locked, the datafiles themselves are not, and are written to as much as they always are. The idea that somehow the datafiles are not written to and that the redo logs are the only place that stuff is written to during the backup is completely and utterly wrong. CKPT is not allowed to write to the header, because that way, we know the earliest "age" of the datafile copy when it went into backup mode, and thus know the point from which redo needs to be applied during a recovery. But DBWR writes to the rest of the datafile perfectly normally.
Number 3 is also important, because it's why we don't leave tablespaces in hot backup mode more than we can help: the amount of redo generated increases because we need a 'starter image' for any block that's modified during the backup.
