Backup Central

hi,
sometimes it would be very useful to compare to different backup copy of
the same file (eg. diff -u /etc/passwd<yesterday> /etc/passwd<3 days
ago>). sometimes I would not like to '--restore-as-of' just compare, ie.
in stead of:
rdiff-backup -r 1D <base>/etc/passwd /tmp/etc/passwd.1D
rdiff-backup -r 3D <base>/etc/passwd /tmp/etc/passwd.3D
diff -u /tmp/etc/passwd.1D /tmp/etc/passwd.3D
one simple command (which even can use the metadata) something like this:
rdiff-backup --diff -u 1D 3D <base>/etc/passwd
would be very useful.
thanks.
yours.

does the --compare feature in 0.13.4 do what you want?
it doesn't actually work for me, but it should do what you want

thanks. what is the current state of the 0.13 branch? when it'll become
the stable version (ie. in the near future)?
thanks.

Actually --compare is only for directories. It tells you which files
have changed and how (e.g. are they new, have they been deleted,
etc.).

It seems the wrong way to go to actually have a --diff switch built
into rdiff-backup. rdiff-backup would end up just restoring the file
and then diffing it, so there would be no efficiency gain.

Instead, perhaps someone could write an external script which would
restore versions of the file (by calling rdiff-backup) and then run
diff or similar on them.
