Dear all,
I have a problem of Point in Time Bare Metal Restore (BMR) using Netbackup 6.5 (both Master Server & Client are using the same version).
Suppose I have 3 successful BMR backups of UNIX system (AIX 5.3.03), e.g.:
- BMR backup "A" (Full backup, day 1, backup ID 001, stored at Tape 1)
- BMR backup "B" (Full backup, day 2, backup ID 002, stored at Tape 2)
- BMR backup "C" (Full backup, day 3, backup ID 003, stored at Tape 3)
All the backups run with IBM Library.
And today I want to restore the UNIX system back to day 2, and I had done a "Prepare to restore" by using the BMR backup "B".
The BMR restore process used an SRT media boot and I just inserted Tape 2 into the library.
And here is the problem... the BMR restore process asked for Tape 1 (backup "A") and it stopped at this condition:
Here is the log at the console screen:
---- BEGIN LOG -----
..
...
....
Restoring /tmp/ file system...
Restoring /var/ file system...
Restore failed.
Failed command: /SPOT/usr/openv/netbackup/bin/bprestore -L /tmp/fifo.6888 -w -H -K -W -O -T -C bendev -S veritas -R /tmp/rename -f /tmp/listfile.fs. rc=5
Bare Metal Restore has failed.
---- END LOG -----
Here is the log from Administrator Console:
Oct 7, 2009 4:34:59 PM - begin Restore
Oct 7, 2009 4:35:04 PM - number of images required: 1
Oct 7, 2009 4:35:04 PM - media needed: PE01L3
Oct 7, 2009 4:35:13 PM - Warning bprd (pid=737320) Restore must be resumed prior to first image expiration on INFINITY
Oct 7, 2009 4:35:13 PM - end Restore; elapsed time 0:00:14
the restore failed to recover the requested files (5)
--> The problem came from /var which has some subdirectories stored in BMR backup "A" (Tape 1: PE01L3).
Then, I retried the BMR restore (Prepare to Restore by using BMR backup "B").
This time, I inserted all the tapes into the library.
The restore process ended successfully, but it still restored some files & subdirectories that belong to BMR backup "A" (Tape 1).
Here is one of the BMR restore logs which looked for BMR backup "A" (backup ID 001):

the requested operation was successfully completed (0)
NOTE:
the rest of the BMR restore logs, were successfully completed: "restoring from image bendev_xxxxxxx002".
I wonder why the BMR restore process always looks for the earliest backup sets, eventhough I did the "Prepare to Restore" using the second/most recent backup set.
Could someone please help me with this problem?
Thank you in advance.
