We can use – `date +%A-%D` in the script.
$ echo `date +%A-%D`

# This script does personal backups to a rsync backup server. You will end up
# with a 7 day rotating incremental backup. The incrementals will go
# into subdirectories named after the day of the week, and the current
# full backup goes into a directory called “current”

backup to a spare disk
I do local backups on several of my machines using rsync. I have an
extra disk installed that can hold all the contents of the main
disk. I then have a nightly cron job that backs up the main disk to
the backup. This is the script I use on one of those machines.
#!/bin/sh
export PATH=/usr/local/bin:/usr/bin:/bin
LIST=”rootfs usr data data2″
for d in $LIST; do
mount /backup/$d
rsync -ax –exclude fstab –delete /$d/ /backup/$d/
umount /backup/$d
done
DAY=`date “+%A”`
rsync -a –delete /usr/local/apache /data2/backups/$DAY
rsync -a –delete /data/solid /data2/backups/$DAY
The first part does the backup on the spare disk. The second part backs up the critical parts to daily directories. I also backup the critical parts using a rsync over ssh to a remote machine
