Disk image snapshots are grossly inefficient as configuration backups.
On any systems with significant file system churn, such as a proxy
server or logging server, each snapshot may represent a significant
and unexpected disk usage on the back end storage array. It's also not
safe or reliable for any database backups, inclding MySQL, PostgreSQL,
or even source control tools like CVS and Subversion.
If you need to preserve system files for just such problems, learn to
do efficient backups. I recommend the old "rsnapshot" tool, available
at EPEL.
