RMAN Backup Restore from tape

Hello Gurus
We have lvl0 RMAN database backup restored from tape but due to some reasons we could not apply recovery on it. On checking the information in controlfile, it identified only the system file and no other file. So, we recreated the controlfile and decided to recover using backup controlfile option (until cancel or until change or until time). However, to my surprise, when I listed the checkpointchange# and checkpoint_time columns of v$datafile_header, I found the difference in timestamps ranging 24 hrs -- which menat we had to apply 24 hrs of archiving to bring all dbfs to a consistent state (before it allowed us to open the db) -- so far so good, it worked that way.
My question is that, while I trigger a lvl0 RMAN backup at say 4PM on 27th July and it finishes on 4PM on 28th July (as I am directly pushing around 1 TB data to tapes) -- what is the consistency timestamp of this backup. In other words, is this backup available for a restore of 4PM 27th July? Or is it available only for a restore of 4PM 28th July and later ...?
Isn't it that RMAN works at block level and when I fire a backup it should give me all the dbf's of that timestamp..?
Appreciate your inputs/comments.

When taking a online backup with RMAN, the datafiles backup is always inconsistent because it needs the archived redo logs generated during the backup to be consistent: http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/intro005.htm#sthref70.
A full online backup can only be used to restore the database to a point in time starting after backup end: if a backup starts at 4PM on 27th July and it finishes on 4PM on 28th July you can use it to restore the database to a point in time after 28-JUL 4PM.

Restore backup piece from tape to disk?

Hi,
Is it possible to restore rman backup piece from tape to disk? Please advice.
Thanks,

Is it possible to restore rman backup piece from tape to disk? Please advice.I dont think so it is related with ORACLE database to copy backup pieces from tape to disk.
You might have any other vendors like veritas, Symmetrix & all. We backup an Oracle database via the TDP application to tape

Restore backup pieces from tape to disk

Hello,
I want to restore the backup pieces from tape to disk. Is there any way of getting those bacup pieces to disk.
I have contacted storage team, that they can't copy the files, only through rman utility the files can be used.
I just need to restore the files from tape to disk. No, need to restore the database. I just need this for future purpose...
Thanks,
Ramesh G

You can try to use LIST BACKUP to get the backup piece name and then use Veritas tool to restore the backup piece from tape to disk.

RMAN RESTORE FROM TAPE DIRECTLY

Dear All,
We are in the process of testing the restore functionality of our production Db. The Backup is taken by Rman which is integrated with Netbackp. The backup files are directly going to the Tape storage.
Scenario
1. We need to restore the backup into a different host which doesn't have access to the Netbackup server and Production Db (Its a DR site)(DR excercise).
2. System team can provide the tape on the standby server.
Concerns
1. How can i proceed with restore in the secondary host.
2. Is there any way to read the backup pieces from Tape and catalog it using rman
If any come across this scenario, kindly share me the solution.
Thanks in Advance

If it is a NETBACKUP device, you can't restore without NETBACKUP. Well, there have been articles written on howto, but they all seem to end in "I just installed netbackup, imported the tape and restored from there."
I NEVER, EVER backup directly to tape - always to disk - most frequently with enough space to store 2 full backups plus enough archivelog file space to span before and after those backups, then sweep the backup location to tape. Recovering from tape can take 50-150% longer. If you use NETBACKUP, install it where it is needed. Going "cheap" could potentially cost the company more in downtime, than the licenses would have costs. If you NEED data, you NEED licenses to run the tools required to recover from a disaster.
The sad part is that should a catastrophic failure occur, it is usually at the most inopportune time.
Companies should treat their data [required to run their business] with the same security and backup strategies as if it was cash in the bank. I have seen a very large company literally throw away over $8M in unrecoverable orders due to impatience with bringing a system back online and not allowing the proper recovery processes to occur. Not having the proper licenses would fall into this category. Can your company afford to lose $8M in income?
Sounds like your company really needs a Business Continuity Review of your DR processes and procedures.

RMAN Restore from tape

Hi,
I have weekly full and daily archived RMAN backup directory to tape. I want to do clone on another server. I have all information HANDLE , TAG etc. What is the best way to restore to another server and clone database. Do I need to restore tape contents to disk and clone?
Thanks

1)Using DUPLICATE TARGET DATABASE command
sample :
On clonedb do following:
rman target <targetconnectiondetails> catalog <catalogdbdetails> auxiliary /
run
allocate channel ch1 <copy the channel allocation command from source database >
set until database to_time('till what time you need data')
duplicate target database to 'clonedbname'
2)From 11g you can use ACTIVE DATABASE DUPLICATE. which does not rely on backups

Restore from tape speed check

Restore from tape : how we can find out out restore speed in MBs? and how to check if there are any bottlenecks/slow speed and what are things to adjust to increase its speed.

Hi DBA2008,
With rman the backup of only the data will be transfered to tape so an almost empty 2g datafile will be faster than a full 2g datafile.
To actually measure the speed you should time a backup to tape and with <list backup;> get information about the amount of data transfered.
Than time the restore this will give you an idea.
Depending on your hardware allocating more channels in the rman command can improve performance.
You could also check the backup system documentation for helpful information to measure/improve the speed.

Backup/Restore from PC Suite with N71 worthless

Hi,
I have used Backup from PC Suite (Version 6.82.22.0) to backup my N71 data before I gave the N71 to a repair shop. The N71 camera was not working.
After four weeks I got a N71 replacement. A brand new N71 with a different serial number which is not good because some S60 apps now no longer work.
But anyway the real surprise I got was after I run Restore from PC Suite to get all data back. The Restore finished without any error but almost nothing useful was restored!!
No Contacts, No Messages, No phone Setup (Themes, Bluetooth Config, Apps).
Huh???
Is this really how Backup/Restore from PC Suite with a Symbian S60 3rd Nokia N71 us supposed to work??
If yes, than Backup is utterly worthless!!
I am not aware that I did something wrong. I have used Backup regularly and never got any error messages.
But it is painfully obvious that the most important data from the phone are not saved!
All the Restore did was restore some audio and image files and the Notes contents.
Regards,
Gagome

you can check the backup log for the details of the backuped content. or try this tool to view the content of the .nbu.

Problem restoring from tape a backup with different retention days

As part of our procedure to test data restore for the SAP platform, recently we tried to restore a backup of the QAS SAP database from tape but had problems . During the analysis we think this problem happened because the retention of the backup on tape differs from the one in the configuration of SAP initSID.utl file; originally, the backup was made to a virtual tape using the brbackup tool /expiration parameter of 3 days, then cloned to a physical tape with a longer retention (30 days).
As a temporary solution to restore the data, we extended the u2018expirationu2019 parameter in the brbackup/brrestore configuration file (.utl) and since we still had the logs of the original backup (.anf file), we were able to complete the restore succesfully. We then changed back to the original the expiration time in the .utl file
We need to run the restore option in Production (PRO) environment but still we are not sure if this workaround is acceptable. Does anyone know if this option is correct or if thereu2019s another known solution for this case

Netbackup related parameters when restoring from tape to a different server

Db version: 11.2.0.2 / Solaris 10
Media Management layer : Symantec Netbackup v7
Production server : qualmh214
Prod DB Name : NEHPROD
We take backup of our prod database using a script similair to the below
run
     ALLOCATE CHANNEL c1 TYPE 'SBT_TAPE';
     SEND 'NB_ORA_CLIENT=qualmh214,NB_ORA_POLICY=qualmh214_rman, NB_ORA_SERV=hlsngt238, NB_ORA_SCHED=Weekly';
     backup incremental level 0 database tag='NEHPROD_full' plus archivelog ;
     backup format 'NEHPROD_%d_%U_%t.rbk' ;
}We have a test server :
dreyth169Every week we need to Clone the above Prod DB from its latest Level 0 Backup stored in Tape.
We have installed Symantec netbackup on our test server.
To restore using RMAN, in run block for the restore, shouldn't NB_ORA_CLIENT be the test server name dreyth169 ? ie. If we keep NB_ORA_CLIENT=qualmh214 (Prod server), then RMAN will do the restore in the PROD !!! Right? That would be a disaster.
What about NB_ORA_POLICY for test server ? Should I create new policy NB_ORA_POLICY for my test server ?

Hello;
Yes, for example if you were doing an RMAN duplicate you would set it to : ( very similar operation )
NB_ORA_CLIENT=target_server
Should I create new policy NB_ORA_POLICY for my test server ?
That's the way I would do it. It may work without it however.
Since you are using oracle 11.2 another option is "Active Database duplication" If your database isn't too large and you have decent network speed and some off peak time once a week I would consider this.
I've used this with great success and you can script it fairly easy in Unix/Linux. If the Remote Host has the Same Directory Structure this get even easier. With a couple of INIT files and a clean up script on the remote this becomes a cookie cutter. Since the job would run from the remote you can avoid RMAN conflicts with your backups.

RMAN backup restoring to new server help!

I'm using Oracle 8.1.7. The production database was copied (datafiles, controlfile etc) to a NEW server that I'm trying to set up as a development DB. I take full database backups using RMAN from the production server, and I want to restore them on the development server. I think I somehow have to specify the filename/location of the backup file but I can't seem to figure out how to do it.
I am not using a recovery catalog.
Any help is appreciated.

If you restore the controlfile backup to the development server RMAN
will "read" the expected location of the backupsets from there.
In 8i you cannot use the CATALOG command so you have to copy all
the backupsets to the same path on the development server as on the
production server.
Once you have your init.ora and controlfiles in place (and created the
expected target directory structure for the database and redolog files),
you can use STARTUP MOUNT and thene RESTORE from RMAN.
I believe that you should be able to rename files in 8i RMAN as well.
If not, you'll have to stick to restoring to the same location.
The key thing is that the controlfile records the "location" of the RMAN backupsets
and the "location" where datafiles are to be restored to.

Speed up restore from tape

The restore from the tape runs always slow and use only one channel everytime. Is there any way we can speed up the restore using parallellism. Please suggest.
FYI - We are not using the RMAN catalog.

Hi Boochi,
Could someone let me know how to run duplicate target database command with degree of parallelism?.Open more channels of both types:
allocate channel tc1;
allocate auxiliary channel ac1;
allocate channel tc2 ;
allocate auxiliary channel ac2 ;
Or if you are using tape channels:
allocate channel tc1 type 'SBT_TAPE';
allocate auxiliary channel ac1 type 'SBT_TAPE';
allocate channel tc2 type 'SBT_TAPE';
allocate auxiliary channel ac2 type 'SBT_TAPE';
