Backup shell script

[mrfloris]

I really need to update my little shell script to automate a few tasks to backup the OMG forums when I need a manual backup.
I keep finding the commands, and my old shell script no longer works.

• backup with tar, using gzip, to a specified directory and name, timestamped, a relative pathed web thing.

• for each site

• backup with tar, using gzip, to a specified directory and name, timestamped, the mysql database.

• each database

• make an archive for the above

• keep up to x archives

• delete oldest archive

• once it's guaranteed to work, maybe crontab it even.
