Backups on MSDP are slow (Slower than Tape)
Hi,
I have an environment of Netbackup 7.5.0.4.
The environment details are as:
Master Server: IBM AIX 6.1, Netbackup 7.5.0.4
Media Server 1 (For AIX systems): IBM AIX 6.1, Netbackup 7.5.0.4
We have and MSDP pool on our media server of 20TB. The filesystem used for this MSDP pool is symantec. (vxfs) with bsize of 8192. The memory on the system is 120GB and it is an IBM Lpar of power7 with 5 CPUs.
When i run backups on MSDP they are slower than the backups taken directly to tape.
Considering the system memory and CPU, i dont think its a resources issue. It might be that netbackup needs some tuning to use these resources.
I need help on tuning the netbackup MSDP for faster backups. I checked the value of MaxCacheSize in the file "/storage/pdc/etc/puredisk/contentrouter.cfg" and it is at 75% "MaxCacheSize=75%".
Any help will be appreciated.
