about backup with crontab

dear all!
i'm a newbie to this forum as well as aix. i'm using aix version 6.1 by ssh remote with no GUI. i'm using crontab for scheduling backup with "backup" command too.
i've created an entry in crontab file to backup some files daily. everything works well.
but i've got a question: how can i backup my files daily without overwriting the previous backup version? for example, the backup file on monday has a name mondbk, on tuesday is tuesbk and so on...and they must not be overwritten for restoring in the future.
could anyone tell me how to do that, please?
many thanks and best regards.

NAME
kep_reload - Update Predict's Keplerian elements SYNOPSIS
kep_reload DESCRIPTION
KEP_RELOAD is a simple utility that forces an immediate reload of PREDICT's Keplerian database through a socket connection while PREDICT is running in server mode. It is especially useful in environments where PREDICT runs continuously, and periodic Keplerian element updates are made outside of PREDICT, such as through scripts run through a crontab. The "kepupdate" script found in this directory is an example of a Keplerian element update script that can be run on an automated basis through a crontab. It is designed to be placed in your home directory under a subdirectory called "cronjobs". It downloads Keplerian orbital data from www.celestrak.com using the HTTP protocol. (The "wget" utility, available from the Free Software Foundation, is required, and is included in many Linux distrubutions.) Type crontab -e to edit your crontab. Simply add the following entry: 0 8 * * * kepupdate and your orbital database will update each morning at 8:00 AM (provided you have a network connection at that time). See the crontab man page for more information on editing your crontab. AUTHOR
