Hi Len,
You're right, there is no error reported and the restore just slow. It's
extremely slow when restoring data file which size is few GB. It just restore
less than 2GB after 1hr...

Hello Song
This is just a wild guess. I first assume that there were no reported errors on
the restore. How much data did the restore say that it restored.?
My wonder is if the files that were backed up had a huge number of blocks with
contents of zeros. Then perhaps on restore netbackup created a sparse file.

Subject: [Veritas-bu] slow restoration on clone volume
Hi all,
I facing slow restoration for clone volume, below is my configuration.
- Netbackup 5.0(MP3)
- L25 library with 2 HP LTO drives
- EMC snap clone (clone oracle database & application database)
- Mount the clone volume on master server to perform backup.
Backup was completed in 2hrs (110GB for oracle clone volume) and 13min (11GB
application clone volume) clone volume. I remove all the data in both clone
volume and perform full restoration, suprisingly after almost 4hrs only restore
about 5GB.
Any idea what going on?
Thanks.
-Song
