rsync - Sep 2008 - rsync with --backup

Hello Guys,

   i'm new to rsync.. and i have a request to fix some things(not
related to rsync)... and i could not find and good-for-me examples on
the net..
   here is the deal: we have an ant-script.. that uses rsync to
update our server's files.. i.e. patch-script
   and request is.. to save files, that are updated...
   and when the patch-script is run again (like, the same one)
back-ups must not be overwritten.

   in rsync i've found --backup and --backup-dir...
   but the thing is.. that i need to store backups on local station
(it is simplier to me),
not on the receiving side... (as backup-dir option tries to do)

   giving --filter='Pp *~' after --backup-dir gives me
   --filter=Pp *~: unknown option

   and
   --backup-dir='user@host1:/path/to/backupdir/' /local/path/
user@host2:/remote/path/
   gives no results.. files are updated, but no backups .. ("user"
are the same on both servers)

i could try to store back ups on host2, then tar them and the copy
them back to host1...

or at first rsync modified file between two hosts to host1 (i.e. make
backup manually)
and then rsync to host2

any ideas?

   version of rsync is 2.6.3 v 28 (and i can not change it.)

Rsync 2.6.3 is too old to understand that option, but in any event, it
would only protect backups from deletion, not from overwriting if the
same destination file is updated again.

You have to pass --backup too.  --backup-dir does not by itself enable
backups; it only modifies the behavior of backups.  In addition,
--backup-dir only supports a directory on the receiver; it cannot send
backups back to the sender.

This is what I would do, except I would use rsync instead of tar to pull
the backups.  For example:

DATE=$(date +%Y%m%d)
rsync -a --backup --backup-dir=/remote/backups/$DATE/ \
	/local/path/ user@host2:/remote/path/
rsync -a user@host2:/remote/backups/$DATE/ /local/backups/$DATE/

That would also work.  If you like, you could have the second run apply
a batch file written by the first run instead of rereading the source.
