Reiserfs and SYMCquiesce utility

Level 3

I'm using Netbackup 7.5, and the OS on the vm client is SuSE 11 SP2 x64 with reiserfs and LVM2, how can I guarantee the integrity of snapshot without SYMCquiesce utility? I've checked at doc " Support for NetBackup 7.x in virtual environments" and reiserfs is not supported.




Usually, for any non-Windows VMs, anything that is not/cannot be covered by SYMCquiesce - Including Red Hat and SUSE VMs that have unsupported file systems - the NetBackup Client should be installed for agent based backups. (So, no VMware VADP type backups.)

Unless, you can time a cron job script to flush and freeze your unsupported file system before each backup job starts, and long enough for the backup to complete. The timing and scheduling could be a bit tricky.

Perhaps it may be possible to utilize the parent_start_notify script on the Master server so that when a VMware VADP job starts, the Master would run your custom script which could call another script on the client for the ReiserFS flushing and freezing. After the backup has completed, a parent_end_notify could be used the same way for thawing.

I would recommend just installing the client for Standard type backups for the whole client, or, VMware VADP type backup for the whole VM plus a another Standard type policy (agent/client based) just for the ReiserFS mount point.

Just to add that there is no need to use netbackup scripts.

Vmware has its own pre and post snapshot scripts for windows and linux vms.

Thanks I'll test your suggests.
