disk to tape copy slow/ backup to tape slow - DP 7 on RHEL 6

Hi folks,

 

I have found a thread about this issue regarding CM on windows, but this does not really help me (most omnirc variables not relevant for linux). We are running DP 7 with the latest patches. Backup to StoreOnce is running with good performance. But copy this data to tape or running a direct backup to tape is quite slow.

Tapelibrary LTO 6; SAS; direct attached to the cellserver. Blocksize 256k; Segmentsize 20000 for tape/ StoreOnce.

Where to finetune?

 

regards

Frank
