Rsync 2.5.7 --delete and --backup behavoir

[Grok Mogger]

Hey everyone,

I'm mirroring a lot of directories from one machine to another. 
  The source machine is running Rsync 2.5.7 and the destination 
machine (the machine holding the mirror) is running Rsync 2.6.9.

I'm using the --backup, --backup-dir, and --delete-after options.

I tested this with two machines running Rsync 2.6.9, and noticed 
that files deleted in the mirror (because they've been deleted 
in the source) are backed up to the backup directory I specify. 
  But when I try with the 2.5.7 machine, I noticed that these 
files are just deleted; a backup copy does not appear in the 
backup directory.

I'm hoping someone could confirm for me that the problem is the 
older Rsync version.  I was just hoping someone could confirm 
for me that this is just the way 2.5.7 behaves.

Please cc me if you reply, I'm not on the list.

Thanks,
-GM
