Hi all.
A while ago (April 15th or so) I posted a patch that allows rsync to
take multiple --compare-dest or --link-dest arguments, allowing
fetching of files not present in multiple trees. I never got any
feedback on it, though, so I'm picking it up again. :) Is there any
interest in such a patch at all?
Below is the usage example i outlined back then;
--start--
[...] Its primary usage is to do incremental
backups on top of eachother. (My current backup system stores each
incremental as a set of files that differ from the latest full.)
Example:
First full backup:
rsync -a somedir full-20040415/
First incremental:
rsync -a --compare-dest=../full-20040415 \
somedir incr-20040416/
Second incremental, on top of first:
rsync -a --compare-dest=../incr-20040416 --compare-dest=../full-20040415
somedir incr-20040417/
(The args must be given in the correct order; Latest incremental first,
last resort last.)
It scratches my itch, at least. Perhaps it can be of use to others as
well. :)
--end--
I'll skip attaching the patch for now, as I haven't updated it to fit
CVS, but I'll update it should there be any interest.
Yours,
Vidar
