Backup performance is slow though using LTO-3 tape drive via SAN
Hi,
Have any idea on getting 10 MB/s - 12 MB/s with LTO-3 via SAN ?
I did try using ufsdump direct to tape with the LTO-3 tape drive which has achieved 19 MB/s.
However, when I backup using NetBackup which could only get 10 MB/s - 12 MB/s.
I agree with Amit.
As I recall 262141 (256K) is the maximum number you can have in SIZE_DATA_BUFFERS. NUMBER_DATA_BUFFERS can be 512 or larger - just make sure you have plenty of shared memory.
Remember to set NUMBER_DATA_BUFFERS_RESTORE as well.
