Hrmm, I can't comment on your idea but, related in some way...

I did spot the multiple --link-dest thing (or was it --compare-dest?)
when skimming through the man recently and wondered - could this also
be used to kick-start from failed backups?

That is, to use all failed backups up until the last successful image
as additional references and once a job is successful, the failed
snapshots could then be deleted.

How it would work?

I guess failures could be added to the .hist file as such, so that
dirvish could track them and include only the last set of failures as

I do backups over the 'net and often find that on the rare occasions
of failure, it gets stuck on a fairly large file - often after other
large files have already been transferred. If it can pick up pretty
much from where it left off, that would save a lot of bandwidth and
lessen the potential for it to fail yet again.
