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
vgcfgrestore - restore volume group descriptor area SYNOPSIS
vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName DESCRIPTION
vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and archive files of VolumeGroupName. OPTIONS
-l | --list -- List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore Vol- umeGroupName. -f | --file filename -- Name of LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfg- backup. See lvm for common options. REPLACING PHYSICAL VOLUMES
vgdisplay --partial --verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to restore the volume group's metadata. SEE ALSO
