If your external drive is mounted at /media/backup-disk , your command
might look like this:
rsync -a --exclude='/.*' --del /home/shirish/ /media/backup-disk/backup1/
The -a stands for archive mode, which makes the destination match the
source in almost all respects. It includes the seven options
-rltpogD, for which grsync has individual checkboxes; see the man page
for the details of what each optionn does. You'll probably be fine
with -a, but you may wish to go through and see which subset of
-rltpogD you care about.
The --exclude='/.*' makes rsync skip dotfiles immediately inside
/home/shirish . The --del makes rsync delete files from the
destination that no longer exist in the source. The trailing slash on
/home/shirish/ is important so that rsync copies it onto, not into,

The command will be similar but with a different source and destination.

You might find Grsync's Simulate button (equivalent to the -n,
--dry-run option) helpful. It also shows the rsync command resulting
from your Grsync options for comparison to the one I wrote above.

You would use cron if you want backups to be made automatically on a
schedule. If you arrive at an rsync command line you like, you can
enter it as a cron job.
If you want to keep multiple backups from different points in the
past, you could use a tool such as rsnapshot (
http://www.rsnapshot.org/ ) to manage them.
