Not that I know of. Because of the complexity of the underlying archive, rdiff-backup does not like a failed or interrupted previous backup attempt at all and tries to remove one if it finds it. Otherwise the risk would be that you corrupt the archive and lose your data history. Although it might be possible in theory for rdiff-backup to continue a previously-interrupted session, the code to do this doesn't exist and isn't likely to be written.

rsync is good at recovering from broken sessions but then it is not trying to do anything so complex. But there are some backup tools based around rsync such as rsnapshot which might work better for you, although they lack the power of rdiff-backup.

hi,

i'm using a synology ds411 nas as backup target. the processor on this
device is very slow, so i don't get a transfer rate of more than 5 mb/s
when accessing it via ssh (cpu-bound). this makes backups for my 500GB
data partition rather painful.

i'd therefore like to interrupt and later resume the initial backup.
however rdiff-backup tells me:
Found interrupted initial backup. Removing...

... and then starts copying the files ... is there any way to resume an
initial backup?

thanks, tim
