I doubt is to do with SSH. My guess is that your (C) backup repository was already somehow corrupted on the destination. So when you tried to run another session to it, rdiff-backup automatically started a regression to get back to a safe starting point for the backup. In itself this can take a very long time, and also regressions of larger archives can require a *lot* of temporary space; if this runs out then the backup might hang. I suggest running something like this on the server:

rdiff-backup --check-destination-dir --tempdir /somewhere/with/lots/of/space /mnt/hda1/rdiffbackup.repositorys/address@hidden

Hi all,

I have 3 windows 7 computers scheduled to perform an rdiff-backup over ssh to a microcore linux server each day at 6pm.

Backups are triggered on all 3 computers at 6pm by windows task scheduler each day.

I'm using volume shadowing to create a snapshot of my files, which is needed for open outlook pst files.
Here's an example.
rdiff-backup --force -v3 --print-statistics B:/Users/%username% address@hidden::/mnt/hda1/rdiffbackup.repositorys/address@hidden

Win 7 PC (A) backup is under 1 gb and works each day. Takes about a minute.
Win 7 PC (B) backup is under 2 gb and works each day. Takes about two minutes.
Win 7 PC (C) backup is 45 gb and takes more than 12 hours to complete. I ran the backup last night at 6pm and it was still running this morning at 11am. I cancelled the backup, and ended up with a corrupted backup.

Is this to do with SSH slowing down the process ?

I hope to find a solution to this problem, as another system I'd like to use rdiff-backup on has over 250gb of data to check.

Any suggestions are greatly appreciated.
