Introduction
This/These procedure/s assume/s that you have used the three step process to install an Ubuntu server with DSpace software.
As your archive grows in size you will be concerned about it's sustainability and make sure it is backed up correctly.
Virtual Systems
If your server is virtualised, then ensure that a snapshot is taken at appropriate intervals to a remote storage location.
Speak to your campus virtual systems administrator about the capacity to take snapshots.
There is no need to apply any of the following procedures if you take snapshots of the virtualised system.
However if you run a bare metal server, then you are strongly encouraged to follow the procedures mentioned below.
Bare Metal Systems
For our bare metal systems, we use "backuppc" for system backups and "munin" for system monitoring.
We identified two old servers that had passed their warranty period and had enough disk space, to use as the backup servers.
We made sure each backup server was situated in a different geographical location on campus.
This made sure that if a fire broke out in one building, with a backup server, we would have another backup server, in another building, safely working.
