We are considering our backup process and it would be interesting to see how some others do things.
At the moment our data is copied (using RoboCopy) across the network to a backup PC (Windows XP machine with a big drive). Once there it is compressed (using 7-Zip) to save space.
With this method we can keep about 2 weeks worth of backups, but we would like more. We do a normal backup on a Friday (starting at 6pm) and incremental backups each week night (Mon - Thur) at 6pm.
Typical user data for a normal backup is just over 100 GB. A normal backup with this much data takes 3 days - not good! Obviously compressing the data on the server before copying it across the network would improve things, but we would like to consider other methods too.
Non user data is copied to a second backup machine in a similar way.
Any thoughts please on the best way forward for this. We will be happy to go with a commercial product. Ease of user data restores is also an issue. At the moment we have to reset permission on user folders when data is restored to them - no big deal, but a nusiance non the less.
Backup onto removable hard disks, daily, stored in fireproof safe.
Volume Shadow Copy everynight.
Followed by a Robocopy onto another PC other end of the school.
Once a week backup on to tape in a fireproof safe.
This way, kids can get there own backups back.
If the server fails, there is an indentical working copy that i can redirect the clients too, so VERY small down time.
If we have a fire, we lose no more than 4 days of kids work since we have weekly backups in the safe (If the school had a fire that bad it took the servers i do not think people would worry about losing 4 days work.
I'm about to roll out an LEA wide solution for remote backups, all schools will be backed up to a central location in the data centre then mirrored to a second location. The data is sent/store in an encrypted state and schools are the only ones with the encryption key.
