Hello,
Say one starts with creating an archive
rsync work -> archive
and periodically (below, i = 1 to N) does
rsync --backup-dir=a_<i> work -> archive
and rsync --compare-dest=archive work -> b_<i>
Then suppose one wants to recover the work directory as it was at
time k.
Using the b_<i> directories, one would merely merge b_k with the
archive directory.
But using the a_<i> directories one would have to merge a_<j> with
archive starting with j=N and going down sequentially to j=k.
Is my understanding correct? More importantly, I would like to
know under what conditions and for what goals people use
--backup-dir; and likewise when and why do people use
--compare-dest?
Thanks,
--Suresh
