Hello Donald,
I use tar and backup all my critical stuff in daily generations and
purge the generations using a find command like so.
find /mnt/backup -mtime +365 -exec rm {} \;
It's CRON and it works..... Here is my backup command...
tar cvfj /mnt/backup/backup.`date +%Y%m%d`.tar.bz2 /etc /home /var
If you want a MIRROR image just setup a raid. I'm a big fan of raiding
and backing up critical files(WITH GENERATIONS SINCE USERS DON'T NOTICE
ITS GONE FOR A FEW DAYS) -- the raid keeps the system safe and the
backup keeps the users data safe.
It's personal preference I'm sure, but you can do tapes and tar it off
it CPIO off the system to those. I'm lazy, I don't like to swap tapes.
Oh recovery is a snap..... "So you deleted you home folder or your
email...... not a problem", you can use ARK to open the tar file and
pull their mail folder for VAR or do a command line command. Raid is a
snap... "Yeah my lights blinking... I'll need to buy a new drive in the
next couple of days".
GHOST is out there too...... along with lots of other GUI based free
linux tools. That stuff gets complicated(or robust if you like it) and
time consuming, my backup takes like an hour and I run it at 2AM
everynight in CRONTAB.
Good luck!
