Hey, folks.
I sent this message to Ben a few weeks ago, but maybe it should be
here instead. I hope it proves useful.
I've started using rdiff-backup to backup to a computer that isn't
always available. I rigged up a complicated system with a wrapper
script and anacron, so that it always tries to run once a day.
But if the source machine also isn't up, I lose a day's backup if the
first run fails.
So I've added a flag to rdiff-backup, --if-older-than. It takes one
of your time_spec strings and only performs the backup if the previous
backup is older than the time specified.
That way I can add an hourly cron job that runs rdiff-backup with
--if-older-than=1d, and I get a good daily backup that retries every
hour if it hasn't happed yet.
The diff is against the devel branch, though it also applied against
the stable branch last time I checked.
Peter
