NBU 7.1--catalog migration

Hi All,

http://www.symantec.com/business/support/index?page=content&id=TECH77448&profileURL=https%3A%2F%2Fsymaccount-profile.symantec.com%2FSSO%2Findex.jsp%3FssoID%3D14192518497756zQ3m1sVeiRr2uTBw6XSgUwN82fBzM5MsWL4S

1..Can i use 'Recovery without Import " option for catalog recovery on a new master server?

i have ran a full catalog backup on old master server A.

Now i have read that in 'Recovery without Import" option ,we copy the /usr/openv/netbackup/db/images/client name folder and scp it to the new master server B on the same location.

But if its a catalog backup,then what directories i have to copy from A to B in order for 'Recovery without Import " to work? i know my catalog tapes id for master server A.

 

I have shipped the tapes to the master server B and inserted in the library with new barcode rules and mew volume pool.

 

2...Is 'Recovery without Import " only used when we are restoring  backup client data from A to B not for Catalog migration from A to B. ??

    Recovery without import is NOT a catalog recovery, it allows only restores to be made, no backups to the tapes will be possible, and commands such as bpmedialist will not show the tapes as they will have no media db entry.

    It also causes NBCC catalog consistency issues, it is only meant as a temporary 'step'.

    As you mention on your post yourself, for client restore you copy /usr/openv/netbackup/db/images/client folders, this is what recovery without import is, same thing as you have called client restore.

    It is not possible or supported to recovery the catalog by coping files across, it will fail, the supported and correct way is a catalog recovery.

    What exactly do you need to do? If you want to migrate to new hardware, followed by upgrade, then Recovery Without Import is NOT the way to go. I agree with Martin. Recovery Without Import is for restores in DR testing. The EMM database with device and media info will be lost. Current media cannot be appended to and you will have no idea when tapes can be recycled and will always run the risk of overwriting tapes with valid backups. Follow TECH77448 as per the link in your opening post to migrate to new hardware. Depending on current and new hardware/OS your steps will either be: 1) Catalog backup on old server 2) Install new server with same hostname and same NBU version and patch level 3) Upgrade NBU OR: 1) Upgrade current master 2) Take catalog backup 3) Install new master with same hostname and NBU version as old upgraded master 4) Recover catalog We can provide best advice if you tell us what exactly it is you need to do along with current and new OS.

    Just reread your first post, so will just highlight. 

    Recovery without import is for clients only, and not recommended due to reasons I've given above, no bpmedialist command for the tapes that have the recovery without import clients data on, tapes can only be read, not written to.

    There is no such thing as recovery without import for the catalog backup, it has to be recovered via catalog recovery to give a server that is in a supported configuration.

    What I don't understand is why you would even consider it, the catalog consists of two main parts, the image db (.f files) and nbdb, and even if you could do recovery without import ( which you can't), you would still have to read the tape so it would take the same amount of time.

    Correct. I am still wondering why you mentioned TECH77448 in your opening post. Have you read it? Those are the steps you need to follow.
