HI All,


We are planning to implment a veritas netback up for Clear case backup.
I have some qureries on that,

1. Can we take tha Clear case backup in the netbackup.
2. As of now we are taking the snapshot backup in the Gtar,can we do the same in the Netbackup.
3. Can we do the incremental backup.
4. Do we need to lock the VOBS before starting the backup in the veritas as we are doing the normal backups.
5. Is it helpfull oipen file backup licence for taking the backup without locking the vobs.
    
6. Is there in speed differs in clear case backup with compare to other backups.
7. We are palnning connect master servers & tape library directly to switch,if so do we get the speed how we are getting the direct NDMP backup.

Thanks in advance,

Sati

DOCUMENTATION: How to back up a ClearCase database
http://support.veritas.com/docs/275602

Modification:
NetBackup does not offer a database extension agent for ClearCase databases. The database can be backed up as flat files using a standard policy for UNIX clients and a MS-Windows-NT policy for the Windows type clients.

Explanation:
The database may have to be locked during a backup. One way to implement this is to use the bpstart_notify script on the client to lock the database or VOBs Use the bpend_notify script to unlock the database after the backup. Sample skeletons of these scripts are located on the master server, in /usr/openv/netbackup/bin/goodies.

We are doing ClearCase backups in our environment and use the following two methods since we have ClearCase in both Windows and Unix environments:

1) On our Unix system we lock the VOBS, stop Clearcase and then use rsync to sync a copy of the files to another volume.  Once the rsync is complete, we start up Clearcase again. Netbackup comes in and then backs up the copy.  The reason for using this procedure is because our Clearcase data on Unix needs to be accessible 24x7.  By using rsync to only sync what files have changed, Clearcase is only down for about 45 minutes every night.

2) On our Windows system we use a bpstart and bpstop scripts to lock/unlock the VOBS, stop/start Clearcase.  In between the two scripts, the bpbkar32 process backs up the data while it is in a quiesce state.  The one drawback with this method is if your backup job starts late, runs long or has poor performance due to resource constraints, you can find that Clearcase will stay down longer then anticipated.  We are currently looking to implement something similiar in Windows like we do on Unix.

Whether incremental backup is working in this case.
RSYNC will it work in the netapp.


Our data size is 3TB again double work So I need another 3TB space to copy the data.
