Hello Jamie
That is one way to do it. Also consider instead, to distribute an external
USB drive for each file server. This will eliminate the network load,
greatly reduce the impact of a failed backup disk, and will eliminate the
backup server together with its single point of failure. It is also easier
to have one set offsite.
Also how much backup do you need to keep (daily/weekly/monthly).
Rotating the backup disks, storing one offsite is also a very good idea.
Now what about backup versions, are you OK with just two backup versions, or
you need more? I am sure you know this, but just to make a point: If you are
backing up daily, keeping two versions, it means you only have one day to
notice a corrupt/lost file before you run it over with a new backup.
Are you going to have incremental backups?
How will you restore from incremental backup? Run the full then all the
incremental ones.
Who will you manage the expiration of old backup generations?
How much time will a full backup take?
How many versions can you keep on each backup disk?
What happens if you forget to swap the backup on a full backup day?
You may want to take a look at Relative Rev Backup http://www.datamills.com
for a good backup solution of the file servers.
This program was built from the ground up to support backup to disk (full
disclosure - I am the chief engineer of this company).
It will take multi-version backups without multiplying the backup disk
space. It
means that with 60GB disk you can have as many as 20 backup generations of
60GB source data, covering the last few months.
It will also manage your backup scheduling and expirations of older
generations - managing daily/weekly and monthly restore points. Plus it will
minimize any backup run from many hours into minutes.
You will only have to swap the disks (if you want two sets of backup disks),
and read the emailed log files.
