Netbackup 7.1 slow backup speed
Hi,
My backup scenario is as follows:
Server -> HBA Fibre Channel 1 -> Quantum Scalar i80
but the backup speed i've attained is a slow 5000KB/s - 40000KB/s instead of anywhere closer to 4Gb/s...
On each Media Server ensure that Program Files\veritas\netbackup\db\config\ exists (it doesnt by default)
in that directory create two files with no extension called SIZE_DATA_BUFFERS and NUMBER_DATA_BUFFERS
Open then using notepad and in the SIZE one put 262144 and in the NUMBER one put 32
Save the file (Making sure notepad doesnt add .txt on the end)
No need to re-start any services they take immediate effect next time you run a backup.
If you back up to disk you can use similar ones - just create another two files with _DISK on the end, you can use the same value for the number but a good value for the size for disk is 1048576
Hope this helps
