Try using `iostat 3` or similar during a backup. Typical 7200 rpm IDE disks can't do more than 100-150 IOP/s or so. > /dev/hda5 94% /mnt/data <--xfs, not used by backuppc > /dev/hdb1 99% /mnt/data1 <--reiserfs, backuppc Eek! Keeping your disks over 90% full is a bad idea. I really suspect that your reiserfs partition is very heavily fragmented. I must wonder if the directory structures have also become fragmented. At least with xfs you can degragment it online. > > You should also check that each disk is running full speed by > > running hdparm -tT /dev/hdX.

Buffered speeds. Those speeds are low if the system is idle. You should be seeing 30MB+ for those disks, probably at least 40MB/s. If the system wasn't idle, please try again when it is. Anyway, seeing the iostat data will let us know if the disks are maxed out or not. -Dave ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
