Re: [Veritas-bu] Netbackup to VTL fast with first tape then slow thereafter

Try looking at the BPTM and BPDM logs (T
for Tape, D for Disk). I don't know if a VTL will go to TM or DM...I would
assume TM since NBU thinks it's a tape still.
Sounds fishy since it changes drastically
after the second 'tape' is mounted. Have you searched to see if there is
a known issue?

| [Veritas-bu] Netbackup to VTL fast with
first tape then slow thereafter |
|
I'm writing my jobs to VTL then using SLP to get them
to LTO5. I've noticed that when i start a job it jumps right up and
the speed is 25MB - 40MB then after the "tape" fills and a second
one is "loaded" the KB/Sec drops to 2MB - 4MB and the speed never
raises for subsequent "tapes".
However when I write directly to LTO5 the jobs average 40MB - 60MB. Using
an EMC Clarion VTL. Any advice would be greatly appreciated.
Is there a log in NBU that would indicate these write speed fluctuations?
Any thoughts would be greatly appreciated.
