    Back-up solutions

    One of the projects I am involved in has raised how some of the docs I have about back-up solutions is a tad out of date ... talking about Zip drives as an option for a back-up solution is definitely a bit behind the times.

    If people would respond to the attached poll, and where possible comment on what their solution is, the amount of data they would expect to back-up, possible even the frequency (eg full back-up once a week and incremental or differential for the rest) it would be helpful

    Any information on costs would be handy too.

    500GB+ of data backed up daily to a directly attached external disk (eSATA or USB3 for speed) rotated out daily from a 5 disk set.

    Primary school installation, use ntbackup with scripts to automate.

    One SMB I deal with does their own thing with 80GB tapes probably LTO using ArcSoft and daily full backups. No love for ArcSoft though as it is messy in its implementation of libraries.

    Various Primary schools - primarily we've been using large external usb hard drives rotated so that one is always kept offsite using Cobian with encryption.

    One 5 and 10 ten TB exagrid network backup and dedupe devices, hp tape library for off sites.

    However we'll be putting another 5tb unit in our boston office, and replicating backups between them, then only doing monthly offsites through tape.

    Fridays:

    Whole network (400GB ish to a home-made NAS (FreeNAS)). This includes everything (all drives, system states etc etc). BackupExec handles all backups except VM's (see below).

    Saturdays:

    Fridays backup is duplicated to LTO3 autoloader (400/800GB tapes)
    Weekdays:

    Differential backup taken of whole network to home-made NAS. Usually takes about an hour and a half. 6 hours later this is then duplicated to tape.

    Holiday specials:

    Each holiday we take a full encrypted backup onto a spare tape and take it home.

    VM's

    We have a number of VM's here which are backed up (snapshots) using custom scripts to another home-made NAS. These don't go to tape as we don't have room (well, looking to squeeze them onto the same tapes as the diffs).


    Think we paid about 2.5k for autoloader and tapes, 1k or so for BackupExec and agents, and a couple hundred for 4 x 500GB HDD's to use in the home-made NAS's so maybe 3.7k for the whole system.

    EDIT: Forgot to say daily diffs are kept 1 week each, while weekly fulls are kept 4 weeks. Special holidays are kept until the next holiday and we also have another spare tape that we use in summer to keep the data for a year before overwriting.

    We use an LTO-1 tape-library. Every day a full backup using 2 tapes. The tapes created on every friday (except the last friday of the month) are kept 1 month before overwriting. We also have 4 month-tapes which are created every last friday of the month. They are kept for 4 months before overwriting. Twice a year (at the end of the schoolyear and at the end of the calendaryear) we create a backup that is stored for 8 years (the maximum time a studens stays at our school).

    We are using a combination of Microsoft Data Protection Manager 2010RC, Symantec Backup Exec 12.5 and Backup Assist 5.

    All of the major backing up work is done by DPM and amounts to about 2TB per night. That backs up to disk (stored for 7 days) and is also backed up to tape every night. Friday tapes are rotated so that we can go back up to a month. Tapes are kept in a datasafe. We use a dedicated server with 11TB of disk storage for backing up, and the primary tape system is a Quantum Superloader 3 with an LTO4 drive in it.

    We also backup admin & financial data seperately to this to an LTO2 tape drive (using Backup Exec). As we need to keep these tapes much longer (7 years for the financial info) it's easier to keep it seperate from the main backup (and cheaper).

    The server was about 2 grands worth a while back and the tape libary was a recent purchase and was about 2500. DPM we aren't paying for yet as it's an RC, but when it goes RTM we'll buy it through the MS Schools agreement. I can't imagine it will cost too much, 100 quid maybe?

    D2D2T solution as follows:

    Backup exec 12.5

    Disk to 2.4Tb Nasbox coupled up to Quantum Superloader 3 with HP LT04 tape drive (16 Tapes), native 800Gb, 1.6Tb compressed encrypted tapes.

    Full Backups Friday night
    Differential Backups Mon - Thursday night
    Duplicate backups of these are then done during the day from the NAS to the tape drive, tape/s stored in fireproof safe.

    Monthly backups
    Term time backups DRPs
    Yearly backups of year 11 Student work backed up onto DVDs and work taken off the servers.

    Year 11 student work stored on DVDs 10 years max then disposed of.

    Not meaning to derail the thread but you realise tapes don't stand a chance in a fire-proof safe in the event of a fire?

    Unless you have some super-duper fire-proof safe (which is probably true)

    LT03 Tape Library. Considering disk-to-disk-to-tape as a development to the backup regime.

    Monday to Thursday - differential (LTO3 tapes) 1 Tape required for all servers

    Friday Full Backup - 2 LTO Tapes in Dell PowerVault AutoLoader

    Tapes Stored on Fire-proof safe.

    We do it by weeks i.e. Week 1 to Week 8 for the full backups, after week 8 the tapes are used again in the full backup. The differential tapes are rotated as normal on Mon - Thursday.

    Admin server - seperate tape backup (in the same strategy of Defferential on M-T and Full on Friday) AIT3

    End-of Term Backup (2 Tapes) - Full

    SIMS End-of tem backup (burned on to DVD) and retained for two months

    Software:

    BackupExec 11d (will be updating to 12.5 soon) installed on the backup server (3Tb) which is attached via SCSI to Dell Autoloader.
