Hi there,

I'm experiencing quite high memory usage during regressions; I have a backup server with only 2G of RAM. I'm doing daily backups. Sometimes a backup fails, and then, of course, rdiff-backup first recovers the most recent backup which did not fail. During this process, rdiff-backup blows up to approx. 3G of RAM. Then things start to slow down (swapping). It's a quite large backup set, about 400G, with a large history. I doesn't seem to be a memory leak, as the memory usage stay at 3G. Just seems a little bit too much in principle.

Has anyone experienced similar luxurious memory (ab-) use during regressions to the previous backup?

Kind regards,
