Offsite Backup Script Linux

Offsite Backup Script Linux

For those of us in the 21st century using disk based backup, we still need to backup to some sort of remote media to keep at a secure offsite location

so basically we have our Backup server that all servers backup to on disk, from there we need to have a script to copy all data to the remote media. There are a few prerequisites:

1) Sendmail/Postfix must relay mail

2) your create /media/Offsite folder to mount your Media

3) you have mounted your /dev/sdb or /dev/sdc to /media/Offiste (mount /dev/sdc /media/Offsite)

4) You have edited the Source Paths for your Environment

5) You understand that Backups are YOUR RESPONSIBILITY and that by using this script you acknowledge that we take ZERO RESPONSIBILITY for data loss, and that  isentirely YOUR PROBLEM if something goes wrong.

Here it is:
