I'm currently using rsync to backup home directories using this:
rsync -avx --delete --backup --backup-dir=/u1/home.bak /u0/home/
/u1/home >> ${log}
I'm trying to move to snapshot backups using this:
rsync -avx --delete --backup --backup-dir=/u1/home.bak
--link-dest=../home.current /u0/home/ /u1/home_${datetime} >> ${log}
This works except I no longer get deleted source files moved to
backup-dir. Is there a way to get this behavior with the link-dest
feature?
Thank you,
Steve

You can already recover files from previous snapshots; are you sure you also want a backup dir? If so, the best way I can think of to achieve this is to fill /u1/home_${datetime} with hard links from /u1/home.current using "cp -al" and then run the rsync command without the --link-dest option. To ensure that rsync does not corrupt attributes as seen through old snapshots, I recommend that you use a copy of rsync with this patch: https://bugzilla.samba.org/attachment.cgi?id=2960&action=view and pass the --no-tweak-hlinked option.
