[Veritas-bu] Backup starts off strong, then does not complete.
2010-04-12 16:26:36
Veritas Netbackup 5.1 environment
Client = windows 2000 server
media server = unix
master server = unix
- Backup unable to complete (full or incremental)
- Starts of fine, tape gets mounted and writing starts.
- Write speed is very good at the start, as shown below (rmt/1).
- Backup progress goes from 0% -> 26% very quickly, with 273664KB (1500 files)
written.
- I also noticed that when I kick start the backup, I see 6 bpbkar32.exe and
bpfix.exe process threads in the Windows Task Manager. Is this normal?
extended device statistics

0.0 45.0 0.0 11519.9 0.0 0.1 0.0 1.5 0 7 rmt/1
- After that, I notice that after 3 hours, the completion rate is still at 26%.
No changes in the number of files written.
- The write speed then just drops to about 11 kw/s.
- Finally the backup either ends with a code 54 or a 150.
Please advice. Thank you in advance.
