The QNAP NAS was £850 I think. So not too bad cost (14 Pence per GB if my maths is correct) :)
What you have to remember is disk backups work a very long time, are reliable and can be instantly restored. That's what makes them better than tape.
The speed of the disks is not a bottleneck at all as far as I'm aware, its the network connection.
I don't think RDX is practical except for very small networks with small amounts of data to back up.
We backup using Veeam to a QNAP 419 at the other end of site. Has meant for the first time in years our backups work without failure every night, week and month. Restoring a single file takes no time at all, and being able to boot a server from a backup is stupidly clever!
Has anyone got a DR solution with another school? So you put kit in their server room and use Veeam across the WAN? As I have see a article that says that Veeam no longer need a WAN accelerator to work.
Were using logmein backup to another drive located in a partner school ... We recipricate and have their drive in our building ....
How much data do you guys have? We currently have around 2.5 TB and use the Barracuda managed backup service using point to point replication, data deduplication and compression to an offsite location.
The service offers us 24/7 support, bare metal and message level restoration. Backup takes around 1 hour per day but clearly data is growing on a second by second basis.
How would you restore all your data in the event of a disaster, how long would it take and have you tested it?
With what I Have read for the documentation I have for all my clients in my new role - have data onsite which is replicated offsite for full DR. In which case you have to compare the time it takes to download said data (with 2.5TB being a lot imho depending on net connection) against paying somebody who collects backup tapes each morning and stores them in a secure facility to dig through the archives find your tapes and get them delivered to you.
Wolfman Alpha website is a good one for working out download times (roughly).
