Issue 5
Automatic Backup
Details
I need to setup an automatic backup process. I don't want to backup my entire system but just some directories. I had a look at the Yast system backup and I think it's a bit overkill for me. Then I had a look at
dar and KDar and seems a more appropriate solution. I'll probably use it along with
cdrecord and
cron eventually.
cron is a daemon to execute scheduled commands. More info about
cdrecord here.
Discussion
Looks like
dar was just what I needed. See the following attached perl script
dobackup.pl.txt to perform back up and burn CD/DVD. A similar script should be used with
cron to perform scheduled backup.
More info about
cron here and
there or even on
http://www.crontabrocks.org/.
Solution
We now have 3 scripts:
-
/backup/bin/doautobackup.script : called by cron. Just calls the following Perl script.
-
/backup/bin/doautobackup.pl : call the following Perl script and send an e-mail containing its output.
-
/backup/bin/dobackup.pl : perform the actual backup and burn a CD
To setup the scheduled task just do:
crontab -e to open your crontab in VI. Then add the following line:
00 3 * * * /backup/bin/doautobackup.script to execute backup every day at 3:00 in the morning.
Those should be added to source control.
