No, because rsync only backs up files from the destination and your
destination is now a new, empty directory instead of the previous
snapshot.
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.
