"You can create a full backup of your home partition with dar by
issuning the following command: # dar -R /home/ -c /var/backup/home-$(date "+%Y%m%d")"

In this context the above example doesn't fit the definition of a
backup. While writing a script you could make a backup of myscript.sh
to myscript.sh.bak even in the same directory, but if upstream of
software provides an example to backup /home to /var I would be careful
with using such software for _real_ backups of important data. Is there
a plausible reason to assume that the software is better, than the
idiotic example?
