    Backups

    Evening All. Just started a new position backups dont seem to be functioning correctly appearing to be down to limited storage. So im just wondering how everyone else backup these days. At my old place we used to backup to a NAS which also replicated to another NAS in different building but i dont have this option at the new site. Currently we have yosemite installed on all servers. I am running a mixture of server 2003, 2008, 2008 core and ubuntu, physical and virtual.

    Current procedure.
    Monday - Thursday - Differential of files
    Friday 1,2,3,4 Full Backup of Files and system state

    Half term - Full backup of everything.

    Any Suggestions would be great.

    I typically backup to a RAIDed NAS and have backup jobs e-mailed so I can see whether it completed or failed.

    Ideally locally to a nas/fileserver and then to the cloud if the internet connection was half decent.

    Or point to point to an external site to avoid having to download critical data from the cloud. In the event of a disaster, bring your offsite target onsite and initiate recovery. Cloud is still expensive and personally not yet convinced that we should be pushing sensitive data this way (Might be just being old-fashioned with this).

    Currently using Barracuda Networks Backup Service (point-to-point) backs up all servers without having to do major setup, emails daily reports. Backup runs incrementally to the backup server with deduplication and compression prior to replication to offsite. Expensive at £24k for 5 years but it is an insurance policy.

    I feel that DR is not taken seriously enough in Education (imo).

    I bought a ML110 G5 hp server and put 3 2tb drives into it and put them into raid0 = 6 TB of fast backup. It cost about £550 (I know it has no redundancy but it is a backup and I hated tapes)
    Volume shadow copies are used day to day the 6TB is just there incase of fire. Oh and it's stored in a different building, no cloud backup but if a fire is big enough to take out the whole school then I don't think they'll mind starting from scratch.

    Are you sure about that?

    If its RAID 0, then I'd say that no, it isn't a backup.

    With all due respect, this is the craziest thing I've ever read... and I've read the source code and design spec for Vista. What about obligations for protecting exam data? Financial records? Etc? Do your SLT know and understand the implications of this "backup" process?

    Friday eve = full backup to local usb hard drive which then replicates to NAS in another building.
    Mon -> = diff backup (local then replicated again).

    As servers are virtualised, at the end of every term the VHDs are copied to an encrypted hard drive and taken off site.

    Do you mean that this is used as a back up server or that is your only kind of DR plan?
    RAID != Backup

    I would feel like its my responsibility to ensure that the network could be rebuilt as it was?
    Surely its easier to get a good backup routine in place than build a new network and explain why everyone's data is gone.

    At my last place they built a Super Micro Chassis Backup server

    The Idea is to replicate the data to the primary school up the road at somepoint.

    Unless there is exam material on there! I know some of the exam boards told our Exams Officer several years ago that hardware failure or loss due to fire, etc. would not be accepted as a valid excuse for not submitting anything in an electronic format that was required for examinations.

    We have:

    Shadow copies for 'My work deleted its self' cases.
    An onsite NAS unit for server failure, backup each night.
    An offsite USB drive that backs up each friday and stays at home in case of fire.
    SIMS and FMS data is copied to the other school I work at each night.

    All backup data is encrypted.

    School fires are common enough (half a dozen or so a year, nationwide, I think I remember reading in the TES once) that there are systems in place to provide temporary replacement facilities - there are companies that specialise in rapid-deployment facilities, paid for by insurance. If your school is burnt down there's no real reason why you shouldn't be up and running again in some fashion within a week, in which case you'll need your user logins, MIS, email, etc all ready to go. Replacement servers can be got to you within 4 hours, you just need to ensure your data is ready to use on them.

    Nightly Veeam backups to disk (5x2TB in RAID5 inc hot spare) then weekly Veeam archive to LTO-5 tape... best of both worlds
    (Using Reverse Incremental mode so the current backup job is always the main Veeam VBK file, makes it easy to archive as a point-in-time copy)

    Ideally would be sending the Veeam backups online but ongoing cost \ hammering Internet connection for the amount of data I want uploaded doesn't make it viable at the moment.
