[ubuntu-uk] Simple backup script

[bodsda at googlemail.com]

I would say it depends on what you mean by 'wrong'

I handle the backups for a local government, so yes, that is wrong, very wrong.

But it depends what you need it for. If you are happy with the retention that that gives you, then that's fine.

The only suggestion I would make is that you should create the backup first, and only if the backup is created successfully should you delete the old one

Subject: [ubuntu-uk] Simple backup script

I've been tinkering with backups and backup rotation today and I have
come across many wierd and wonderful backup scripts of varying
complexity.

Is there anything wrong with using something simple like this? (except
of course for the lack of validation).

Basically, let's delete anything over 7 days old and then make a new backup.

#!/bin/bash
find /home/username/backup/*.tar.gz -mtime +7 -exec rm -f {} \;
/bin/tar -cpzf /home/username/backup/`date
+%a"-"%d"-"%b"-"%y"-"`backupfile.tar.gz /var/www
