I am seeing a very strange problem after transitioning to backuppc 3.0. Backups are taking considerably longer, and i am frequently getting out of memory kernel panics messages dumped to the syslog.My previous config was a P3-450 w/ 256MB ram, 10GB Internal drive, and a 700GB external RAID-5 array. This machine ran debian 3.0 and Backuppc 2.x ( i frequently updated it).The new machine is a P3-800 w/ 256MB ram, 10GB Internal drive, and a 2.0TB external RAID-6 array. This machine is a fresh install of debian 4.x and runs Backuppc 3.0Both machines had aproximately 800MB of swap, and were configured to do backups via RSYNC/RSYNCD or SMB.I know that the first machine was slow, it took a whole day to do a 100GB backup over a 100Mbit link. But the second machine is taking many days to complete the same job. I started a full backup on the 3rd of october and it is still running today.I have already run extensive diagnostics on all the hardware, so i know that the machine is fine.Before i start racking my brain, i wanted to find out if anyone else had experienced this type of problem after moving to backuppc 3? Has anyone seen memory leaks with backuppc running on debian 4?
No, but 256 MB seems like not a lot of memory if you're using rsync and arrays that large. Swapping will kill performance. Are you running your first full backup? I have no idea why it would be slower now than before.
