I should also mention that there are totally valid reasons why the dir
might be huge on day4. For instance, if someone changed the mode on the
files from 664 to 644 then the files cannot be hard-linked together even if
the file's data is unchanged. The same goes for differences in preserved
xattrs,
You could rsync the current day4 dir to a day4.new dir, and list all the
prior days as --link-dest options. Make sure that you're using the same
xatt/acl options as your official backup command (the options may or may
not be present) so that you are preserving the same level of info as the
backup.

The disadvantage (for me) of jdupes is that, given 40 or so incremental

Hi.
Is it possible that, if day4 is consuming too much space, that day3 was an
incomplete backup?
The rsync wrapper I wrote goes to a little trouble to make sure that
incomplete backups aren't allowed. It's called Backup.rsync, and can be
found at:
https://stromberg.dnsalias.org/~strombrg/Backup
I run a simple self written incremental backup system using rsync's
--link-dest option.
Occasionally, because I've moved things around or because I've done
something else that breaks things, the hard links aren't created as
they should be and I get a very space consuming backup increment.

Hi!
I use rsync batch mode for incremental backups. That is, I create an
on-line backup with rsync, and use the --write-batch flag to
additionally generate my delta, which I send off-site. To restore, I
download a full backup and apply the deltas with --read-batch. This is
quite a lovely setup
David,
I haven't found any other file systems that directly support HFS meta

Hi David,
I am also interested to know if anyone has found a file system which
will store Mac OS X meta data. In the mean time, I would suggest that
you back up to another Mac OS X machine with a pull backup strategy.

I'm trying to use the rsync algorithm for incremental backups.
After a quick look at rsync I saw the batch mode operations,
and I thought that maybe I can modify them for incremental backups.
What is needed is to add an option to save the checksums of all
the files of the level 0 backup
Just saw this thread in the list and thought I'd point out a little bash

Hi,
We're doing offsite backups using rsync, more or less the cookbook example
using:
rsync --numeric-ids --compress --rsh=/usr/bin/ssh --recursive --archive \
--relative --sparse --one-file-system \
--compare-dest=/vol/backup/$HOSTNAME/current $HOSTNAME:$DIRECTORY \
/vol/back
