Subject RE: [firebird-support] Re: Looking for Linux backup script
Author Graeme Bruton
Hi Lou

I put mine in a file under "/usr/local/bin/" called "dailybackup" which
crontab runs from Monday to Friday to 23:00 and contains the following:-

BACKUP=/disk1/backups/Daily.`date +'%a'`.bz2
tar -jcf $BACKUP /what_I_want_to_backup /maybe/users/mail/files /etc ....

This creates a zipped file called "Daily.Mon.bz2.

What you need to do is "man date" to get the context of what you want your
files to be called. In this instance, "%a" is an abbreviated week day name.
What you would then add is your gbak command, let that get backed up
somewhere, and then let the above zip it using tar and name it according to
your specs.

Hope this helps.

Don't forget to restore the backup file to a temporary location to
make sure it is valid as part of your script. When your hard disk
bombs, it is not really the best time to start wondering if your
backups were successful.
