What OS are you runnnig? What filesystem? What backup method (ssh+rsync, rsyncd, smb, tar, etc)? 75 tps seems to be a bit slow for a single disk. Do you have vmstat, iostat and/or top output while a backup is running? > But I couldnt find any solution to this. Is there a way to get this > faster without changing to faster disks?

This usually isn't a problem for actual backups, but will help speed up the nightly maintenance runs. -Dave ------------------------------------------------------------------------- Take Surveys.
