comment Out-of-memory kernel (3.2.0) panic (Debian 7.3) even though offending process was killed
Debian defaults. This is a very low-load (samba file) server, the backup task is by far the most taxing one it has all day, especially the incremental ones. swappiness=60, dirty_expire_centisecs=3000, dirty_ratio=40, dirty_background_ratio=40 Looks like I should resize some partitions to make room for 32G of swap - this is really silly. Maybe I can get rdiff-backup to skip incremental backups for huge files, I don't think the simple file copies try to allocate RAM for the entire file.

Do you also happen to know if I really have to have as much total RAM as the size of the largest file handled by rdiff-backup? Because that seems to be the problem. It could be that this (only) happens when calculating incremental backups, I only looked at the "leftovers" briefly thus far.

comment Very different results from df after a few seconds
I think rsync creates temporary files while the file is being transferred. If you have some large individual files during transfer the temp. files will take up space, they will be removed once transfer of that file is complete - lots of space free again all of a sudden.
