    Secondly RAIDed NASes are quite common, whereas most USB disk drives are just one physical disk. If your servers are RAIDed as well as your backup to a NAS, you limit the risk or probability of losing data.
    Fair point on the first item, although on a completely personal note if our server room burnt down, the rest of the school would be burnt out with it and a few days worth of incremental backups wouldn't be too much concern.

    Regarding RAID's NAS boxes - I don't trust these. Fine if a disc dies, but if the NAS raid controller goes, your data tends to be lost anyhow.

    One for 2014/15 I think when our NetApp filer is due for replacement.
    Although I have considered replicating to a separate ESX host in another building with DAS.

    That really depends how big the school is or where an event occured, in the example of fire or flood.

    There are many brands/choices of NAS out there. I suppose an alternative would be another Windows Server box at the other end of school.

    I just want to find a long term storage solution for monthly backups... also need to backup SQL and Exchange mailboxes...
    We do a mixture of system states and raw data. Our FRDC has its system state backed up to ensure a copy of AD and we do a full system backup on our exchange server. Everything else we robocopy onto a HDD in a HDD dock.

    Regarding data recovery, we use powershell to setup accounts automatically from a database sync'd with SIMS, so to do a full restore, we would just need to install 2k8 & powershell, etc, setup a simple framework of folders and run a powershell script to create user folders from the database and restore data back from the HDD.

    Sounds good... But have you tested this as if it was a real situation..

    There are procedures in place for getting a school back up and running in the case of a serious fire or similar - there are a couple of companies that specialise in setting up temporary schools at very short notice. If the school burnt down, I imagine one of the first things our SMT would want would be access to the MIS for pupil contact details and so on.

    When I started recently, the network drives were full. They're only 100 GB each, and RM wanted to charge out the arse for about £450 to double the size, which is ridiculous. Since I'm an apprentice, instead of asking for more money to experiment with a NAS, I thought the quickest and cheapest solution would be to order two 1TB WD Passports, and back up each drive on each.

    It works for now, but I do eventually want to try a NAS. Though the budget seems to need to be more focused on updating the outdated classroom equipment we have right now.

    We do disk-to-disk overnight and then disk-to-tape during the day, with EOW media stored in a safe in a different building. One thing I seldom read about during such discussions is this: if your server room burns down then you've probably got bigger problems than your hardware, such as all your cabling coming into your comms cab. I suspect that would be the longest part of any recovery job.

    I'm quite lucky from a DR point of view as we have 3 sites, 2 down the road from each other, the 3rd on another street. There are very few disasters likely to affect all 3 sites...even a plane crash would struggle (though a big flood might not)

    Anyway I back up to a NAS at the main site, which is at the other end of the building to the server room. Then I duplicate to a USB HD and take to the 3rd site. And backup straight to USB on the second site and again take to 3rd site. 3rd site is backed up to 1st site.
    Will be adding another NAS in the summer to the second site so they can back up to each other and along with the USB HD's essentially have a system where everything is backed up everywhere.

    Yeah I've thought that before - server hardware is relatively quick to get up and running, cabling isn't. Though I guess in such a scenario draping some CAT5 along corridors and between windows wouldn't be the end of the world until it could get sorted properly

    Curriculum and admin are backed up to the Cloud nightly via the LEA -so the covers all the DPA questions. Assuming that the LEA can be trusted! 30 days instant retrevial rest on tape for request.

    MIS backup taken weekly and kept on a PC on the other side of the school. Critical documents are the same.

    About once a term I back a MIS and critical backup stick it in a TrueCrypt container and whack it on our partner schools server and vice versa. Neither can access the others as the passwords are kept on site at the respective schools. As the schools are on the other side of the city that provides a little bit of extra security.

    Can see why you wouldn't want to let the other school keep your TrueCrypt password, but if it's really a DR situation on your site, how are you going to get hold of the record of the password?

    I have a large site with our music block as a separate building so backup to disk in there. I use a piece of software called Veeam which I CAN NOT RECOMMEND ENOUGH! so fast with amazing compression and quick restores!.

    Is VEEAM just for virtualised servers?

    Didnt see anything on the website for normal servers
