[Veritas-bu] Netbackup to VTL fast with first tape then slow thereafter
2011-06-09 14:02:30
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.
