Powersandseven:

First of all, the /CLONE switch alone automatically removes
any file from the destination that is no longer present
in the source immediately (without waiting for 3 months).

If you want your version of /CLONE to preserve files that
have been removed from the source, then, you should use
/CLONE/Z0 (the /Z0 switch disables the /ZY switch that
is included in the /CLONE shortcut).

Now, by disabling the Zapping feature (removing files
from the destination which are no longer present in the
source), you will start accumulating tons of files
that are usually not important.

It is a good strategy to keep them for 3 months before
removal (if you can afford the extra space). To do so
requires a different command:

xxcopy \\server\c\backup-dest\ /rsy/pd0/s/r/h/db#90

(make sure that the directory name is spelled correctly
--- the /pd0 switch is suppress the warning for checking
that)

So, my suggestion is to create a batch file to run the
two lines:

mybackup.bat
-----------------------------------------------------
xxcopy \\server\c\backup\ /rsy/pd0/r/s/r/db#90
xxcopy c:\ \\server\c\backup\ /clone/z0
-----------------------------------------------------

(adjust the server and directory names as well as the
duration to keep old discarded files /DB#90 keeps
files that are 89 days or younger).
