Restore to alternate Master server domain

Created: 29 Nov 2012 | 8 comments

Hey all,

I am looking for information regarding a restore procedure to restore a tape's contents from a primary environment to a DR environment.  Is it possible to import a tapes contents from one master to another without importing any catalog data? Just curious if someone can point me in the right direction for this procedure if possible. 

Greatly appreciated...

with all honestly .... i will recomend you catalog importing at DR location will be nice.

but...If you have the habit of taking dangerous shortcuts, then it is possible by transfering image database from primary master to  DR master server.

What does importing the catalog do for you when restoring to a DR location? Isn't it possible to just import a tape into the DR robot and have the DR master server scan the tape and restore the contents of that tape to a desired location?

Just trying to see what the catalog restoration or import at the alternate site really does.  I forgot to mention that currently the alternate master server hostname is different than the primary master server hostname.

Here goes:

You cannot do a catalog restore in DR if the server name is different

You could copy the images folder for the client to the DR site but that would be missing its tape information so that would need to be dealt with as well as the owner of the backups being worng (the media server that did the backup)

Best way is to do a phase 1 and phase 2 import of any tapes sent to the DR site - that makes a restore perfectly available to you as it imports the backup information, tape information etc.

Do make sure your media id generation rules are the same on the DR site as on the live site

The only other way of making things really easy is to use de-dupe and AIR so that backups are always available and ready for you on disk

So essentially, the downside to doing this is only the fact that the process may take longer due to the additional import process needed?

Is a phase1/phase 2 import a viable solution or would you say it's preferred that your alternate environment possess the same hostname as the primary so that a catalog import is possible?

 I am still getting experienced with Netbackup and I really do appreciate the insight.  Is there any official documentation covering the restoration of images to an alternate environment?

If you want a true standby Master Server for DR purposes then use one with the same name, installation directory and version / patch level and do a catalog restore

The only better way is using de-dupe and AIR

Hope this helps

is this catalog restore or ordinary backup restore ?

b,coz initially you mentioned " regarding a restore procedure to restore a tape's contents from a primary environment to a DR environment."

This is an ordinary test restore that involves simply restoring a random image from the source domain to the target domain.  I wanted to clarify what options were available as far as restoring was concerned in this type of scenario.  I wasn't sure if a catalog import was needed neccessarily if the domains were using different master servers entirely.  Now I see that options are available to have the target domain create it's own information headers on the tape being imported which includes that info in it's own catalog file on the target master server.  At that point, the tape is able to be restored based on that info being created.

I have also read that it is possible to do a partial catalog restore that involves only copying over specific images (based on the client) to the target master server directory of <install path>\db\images.  Still reading about this process though.  Is that what you were mentioning earlier Yogesh9881?

Please correct me if I am wrong in any of these points.  Want to make sure I am looking at this right.
