DB2 BACKUP on tape & disk

Hi Experts,
Can anybody tell me how to take the backup and restoration of DB2 version 9.x what backup parameter i have to change for taking backup on TAPE or DISK.
Thanks

Hi kumarraju,
you just have to specify:
e.g.
backup db <dbsid> to /tmp
or
backup db <dbsid> to /dev/rmt0 or something
For details refer to the DB2 online doku at:
http://publib.boulder.ibm.com/infocenter/db2luw/v9/index.jsp?topic=/com.ibm.db2.udb.doc/welcome.htm
search for "backup database" and you will see the complete
syntax diagram of the backup command

How to move rman backups on tap from disk

Hi,
I have rman backup files on the disk, now how we can move these files to tap. is there any rman command or is there any script to move.
Thank you!

Do you use FRA (Flash recovery area)?
If you use FRA then configure RMAN to take backup to tape. And backup fra to tape.
RUN
ALLOCATE CHANNEL ch0 TYPE ‘SBT_TAPE’;
BACKUP RECOVERY AREA;
RELEASE CHANNEL ch0;
If you don't use FRA then you can backup your backupsets which are on the disk to tape.
RMAN> BACKUP DEVICE TYPE SBT BACKUPSET ALL;

Rman backup to disk 2 Minutes; Backup to tape hours

Solaris 10
Oracle 10gR2
MML Netbackup 6.0
I have the following scenario
Rman backup to disk < 2 Minutes; Backup to tape takes hours
and occassionaly fails with a media manager layer error.
Any suggestions to speed up the backup to tape?

A backup of under 2 minutes . . . not very big.
A backup to tape of hours?
I don't think that is your problem . . . I think you need to check and see if your tapes are valid. If Oracle fails at the end of a backup to tape, it sounds like the tapes are 'bad'.
If the tapes are good: Then look at why it is so slow - I would 'guess' network backup.
Can you backup to disk and then send them to tape?

BRtools Two-Phase-Backup to remote disk and remote tape drive

Hello,
i want to two-phase-backup a SAP-System to a remote disk and from there to a tape drive.
Backup to remote disk works fine, but can i use brtools to write the backup-files from the remote machine to a tape drive that is connected to the remote machine?
I'm using SLES 10 on both machines.
I can't find anything on the SAP Documentation to this. It ist possible to backup to remote disk and to remote tape, but it is not clear that it works when in Phase 1 of the backup the files are written to a remote disk. It seems like i can only tell brtools to backup the files from a local disc to a remote tape-drive, is this right?
Thanks in advance for your help.
Regards
Phil

Hi Nirmal,
thanks for your answer.
But i can do disk to tape Backups, when i choose "Backup of Disk Backup" from BRtools, i see a list of all Backups i wrote to the local disk and can write them to remote tape by using pipe as backup device.
The only thing is, my Backups are stored on a remote disk, and from there it seems i have to write them to tape with cronjobs using a shell script. That's not my favourite solution, but it's ok.
Regards
Phil

DB6 backup to tape

I'm new to DB6. We have just migrated our SAP ECC6 sytem from Oracle 10.2 to DB2 v9.1(FP3).
If I try to backup to tape, I get the following message whether the tape is blank or not:
sapdev:db2hsd 4> db2 backup database HSD online to /dev/rmt0.1
SQL2031W Warning! Please mount the target or source media on device
"/dev/rmt0.1".
Do you want to continue(c), terminate this device only(d), abort the utility(t) ? (c/d/t) c
SQL2059W A device full warning was encountered on device "/dev/rmt0.1".
Do you want to continue(c), terminate this device only(d), abort the utility(t) ? (c/d/t)
If I backup to disk I have no problem.If I look @ db2diag.log, I see the following information:
2008-08-08-13.10.38.537853+120 E7613028A695       LEVEL: Error

The sytem is definitely seeing the tape drive, because if I use the following command, it works:
db2tapemgr DB HSP DOUBLE STORE ON /dev/rmt0.1 FORCE
My one concern, with the above command is that I have to use the force option.
When the system was still on Oracle, we used brbackup and brarchive without a problem.
Is there something else I need to configure to see the tape drive "properly"?

Hello Jean-Jacques,
There is a restriction on the number of fixed block sizes that can be used when backing up. This restriction exists because DB2 writes out the backup image header as a 4-KB block. The only fixed block sizes DB2 supports are 512, 1024, 2048, and 4096 bytes. If you are using a fixed block size, you can specify any backup buffer size. However, you might find that your backup operation will not complete successfully if the fixed block size is not one of the sizes that DB2 supports:
[http://publib.boulder.ibm.com/infocenter/db2luw/v9/topic/com.ibm.db2.udb.admin.doc/doc/c0006201.htm]
There is a SAP DBA Guide: DB2 for Linux, UNIX, and Windows on SAP Marketplace (Installation & Upgrade Guides -> SAP NetWeaver -> SAP NetWeaver 7.0 2004s (if this is your system's version) -> Operations, then choose Database-Specific Guides -> "SAP DBA Guide: DB2 for Linux, UNIX, and Windows", which has extensive session on how to setup your tape drives to work with db2 backup.
As well, you can check out OSS Note 141872 that talks about a similar problem.
I hope it helps.

Taking Backup on tape Getting Error

Hi,
My production server is running with SuSE Linux 10 SP2 with DB2 9.7 database.
I have LTO4 tape drive directly connected to my Production server
I am able to take backup to disk but when I am trying to take backup to tape I am getting error as below.
SRSPROD:shpadm 38> db2 backup database SHP to /dev/st0
SQL2031W Warning! Please mount the target or source media on device
"/dev/st0".
Do you want to continue(c), terminate this device only(d), abort the utility(t) ? (c/d/t)
I have full permissions on tape
SRSPROD:shpadm 39> ls -l /dev/st0
crwxrwxrwx 1 root disk 9, 0 2010-04-26 08:57 /dev/st0
Thanku

Hi,
Before we start into deeper analysis I would like to confirm that normal
writes to the tape works e.g. with OS meanings. Could you please test
if you are able to put an archive with tar to the tape?
e.g. with "tar cvf /home/<user> /dev/<TAPEDEVICE>"
What happens if you select continue as this message is only a warning?
Does the backup then end with an error?
If so please update with the error you recieve.
Regards,
Paul

Backup to tape failed in DPM 2012

I am new to DPM.
We have configured a protection group for short term goal with 7 days retention range, Synchronization frequency 6 hours. And recovery points are based on synchronization (means 4 Recovery points per day and DPM will have 28 valid restore points after a
week...!!??). In long term goals we have configured 2 recovery goals to tape ... 1 recovery point per week on saturday (retention 4 weeks) and 1 recovery point per month (on day 1 with retention range of 1 month).
Now Im getting PG status "backup to Tape failed" I want to know the process how DPM will check and verify recovery points on disk before writing them to tape.
Based on my protection group settings, there should be 4 recovery points on disk everyday. but there is something different result...see the below in reply.
My queries are:
1) On Saturday weekly tape job, does it require DPM to have valid 28 Recovery points?? What happen if any RP missing.
2) Due to some issues, if weekely tape backup failed on saturday. Can we resume it on monday,tuesday..with corrective actions??
3) the DPM process of verifying disk based recovery points before writing them to tape.

Hi,
<New questions Snip<
Q1) For file/volume protection, synchronization is not RP. We have to configure RP creation time manually.
A1) Correct, file synchronizations are not recoverable, only "recovery points" are recoverable.
Q2) For application's (SQL,EXCH,SHAREPOINT) recovery points each synchronization job will create a RP as per synchronization frequency.
A2) Yes, for applications like SQL and Exchange that support incremental backups, then incremental synchronizations are recoverable.
Q3) If a tape backup is getting failed due to invalid RP on disk, I am creating a manual RP with Express full backup(for databases) and a RP with Incremental(for file/volume share), then resuming tape backup. Is it correct way to do this?
A3) Yes, A manual Express full for application data or a manual recover point with synchronization for file / share data and that should allow you to manually create a new tape based backup from the alert.
Q4)How to enable the verify option to check the integrity of the tape backup?
A4) Simply modify the PG that has tape based protection and while on the "Select Library and tape Details" page, select the option "check backup for data integrity (time consuming operation)".
Q5) And what is Co-Location..!!
A5) Tape co-location allows data from different protection groups to be written to the same tape. You need to make a tape protection group set using the "Optimize usage" feature under the management - Libraries page of the DPM console.
See the following TechNet pages.
Tape Optimization Setup - Create-Modify Protection Group Set

Backup to Tape ; Some Design questions

Version : We have DBs on 10.2, 11.2 Enterprise Edition
Platform: Solaris 5.10 SPARC
Helloo..
Never worked on Tape before. Currently , all our RMAN Backup Pieces are going to Disk and from there Sysadmin moves it to the tape using TSM.
1. If you were to design a Backup strategy, would you backup to Disk first and then get the Sysadmin to
copy to Tape OR backup directly to Tape?
2. Do you guys backup Level_0 backup on TapeA , Level_1 backups on Tape B
and Archivelogs, Control file , Spfile on TapeC
3. RMAN Backup to Disk or Tape; Which is faster?

1. Best practice directly to tape
Adv: a. Longer retention inexpensive. separate tapes for weekly, monthly and yearly rotation.
b. Can compress
c. Inexpensive for VLDB.
DisAdv: a. Needs Tape vendor (MML) license to directly write to tape.
b. Storing tapes and tape maintenance.
c. Slow process
Writing directly to Disks
Adv:a. For smaller databases with less retention.
b. Faster backups locally
c. Faster restores.
DisAdv:a.Media failure
b.Does not work for VLDB
2. Its expensive to separate tape drives as they come in big sizes.Have maxsetsize or section size set to few GBs for faster read to restore. RMAN can easily identify the files it needs for recovery and the storage vendor have the catalogs that helps. You can separate tapes for permanent retention. Deleting the obsolete backups is messy as you have to load the right tape, operational difficulties.
3. Refer #1.

Snapshot rollup with Long term backup to Tape

I need to reconfigure the short term disk storage, and wanted to know if I create a Long Term backup to tape, does that
store or encompass all the "snapshot/short term" backups that I have on disk?
If so, I will be able to remove all my disk backups, reconfigure it as needed, and re-enable the short term backups without losing any of my historical backups. (For Legal reasons)
Thanks!

Hi,
No, Long term to tape are also "point in time" backups and if started now will only contain new recovery points. The ability to make backups of previous recovery points is not very easy, you basically need to restore a disk based RP to tape, unfortunately,
every restored recovery point to tape requires a separate tape.

Rman Backup in Tape - Restore

Hi All,
This's my scenario.
I am using oracle 10gR2 on solaris 10. I configured Rman for my database. I ran the backup command on monday and again tuesday and again today also.
All backups are stored in tape not disk. now I have a problem, so I want to restore the Monday backup from tape.
How to tell these to Rman. If I simply mentioned the restore command, hope Rman will restore the latest backup. But I want to restore the Monday Backup.
Could you anyone help me on this..
Many Thanks
Senthil

when ever you are recovering the database to certain time,certain scn then it is a incomplete recovery only.
after completing the recovery by specifying until time or until SCN oracle will not allow you to open the database.
It will ask you to open the database in resetlog mode.
The step which admin given is correct one but after that you have to open the db in resetlog mode

Hi,
thanks for the suggestion, but all permissions are ok.
The db2 user is in usbshare group:

We cannot use NFS, the disk is not in a system, it's an external disk connected directly to the network.
Regards and thanks for the replies.
Sonia.

Finally we fixed this problem.
The problem was the user owner in this filesystem, the owner must be db2<sid>.

Oracle Suggested Backup, to tape only - Tivoli Storage Manager

I´ve been asked to cancel future backups to disk and to setup oracle´s suggested backup to the tape device only (which underwater is the tdpo from Tivoli´s storage manager).
This way the expensive disks can be freed from recovery data.
I´ve had my share of problems with the tdpo, but besides the problem of this gateway driver between RMAN and TSM I would like to know if this is best for the whole suggested backup strategy.
Somehow I´m not convinced in backing up to "tape" devices only; for it is slower than local disks, and because we had problems before with the driver, but there may be a lot more reasosn why I should or should not accept this desired goal to be best for our company.
I hope some of you can help me straighten my vision on this.

The biggest problems I think we might face are the
big question "who is responsible for what", and the
administration of non Oracle systems/methods to
perform backupsi have no problems with such a setup. i provide the rman skript which will be called by TSM.
the TSM admins notify me if the backup failed. retention on TSM side is disabled, only RMAN deletes obsolete/expired backups.
All I want to care about is performing a backup to
Disk, or Disk and Tape, or just Tape from within
Oracle/RMAN and read the ouput from here.
Now where these external tape labraries like TSM come
in there will be more administration for the total
handling of a backup job. It´s not only RMAN, but a
tdpo and a TSM server which need to be monitored
closely. of course TSM has to be monitored but if you already have invested an infrastructure you should use it for every type of backups.
Sadly Oracle has yet to come up with it´s secure
backup for TSM systems, but I think it would be best
if I could let Oracle solely in charge of its own
backups.if TSM retention is disabled, RMAN has absolute control.
Then again, I don´t know if anyone has good
experiences with TSM as the only backup provider for
Oracle backups. (so no disk backups)it works very good. use staged pools on TSM. primary pool should be diskpool, secondary a tapepool. you can configure TSM to move the data from disk to tape based on fill level or age.

Differential backups to tape

We have a number of medium size client sites that we support with an average of 150 users at each site.
Their file server data repository has now grown to just under 2T . We backup with SCDPM 2012 SP1 onto LTO5 1.5/3T standalone tape units.
DPM does not allow you to create a Protection Group with just the differential data from the last full backup onto tape.
We have the desired recovery point options when backing up disk to disk but not directly to tape – could you check if this can be configured somehow.
Backup windows now span well into business hours due to this and in some cases take more than 24hours to complete – The latter is due to backing up millions of files in our current email archive solution repository.
We obviously do not require a full daily backup of this data and the backup to disk options requires the client investing in addition hardware for each of it 20 sites which they see as not feasible.

Hi,
If you are only performing Disk to Tape (D2T) backups, you do have the option to perform Full+Incremental short term backups. The Full can be on a weekend day, and perform the incremental backup during the week.
If you are currently doing Disk to Disk to Tape (D2D2T) - then what you desire is an option to perform Full+Incremental long term backups which DPM does not support.
