Backup for large number of Size

[Twinkle_Sapra]

One of our unix(SUN) server having mount points with some of folders having files over 15,00,000. Every time backup getting failed with 13. Any chance or best practise to get backup without snapshot.

Best Practise is to use FlashBackup. You only need a small volume (5-10%) as snapshot destination.
The only other way to bypass filesystem overhead is to unmount the file system and to backup the raw volume. The problem with this is that you need to restore the entire raw volume and ensure that the destination contains the same number of disk blocks (or more), not just same size.
FlashBackup also backs up the raw volume, but you have the advantage of being able to restore individual file/folders.

Try to increase CLIENT_READ_TIMEOUT

The default is 5 minutes, but that properly not enough for Netbackup to built it's worklist - especially for incrementals .  Try setting it to 43200 (12 hours).

But do consider Marianne's suggestion.

APOLOGIES

Client is LINUX BOX( GFS2 ) file system not SUN. Is it possible to take flash backup with this situation.

With reference to document

http://support.veritas.com/docs/316924

“ FlashBackup on Linux supports only the VxFS file system on VxVM volumes. For Linux clients, no other file system is supported, and VxFS file systems are not supported without VxVM volumes. “

Is there any solution.

Thanks in Advance
