    Shared areas on school networks

    Hi was wondering if i could share my dilema with the rest and try to find what policies you have in place and to see if they are better.

    Like any school we have shared areas which pupils and staff can access. We have 3 main areas (staff common, student common and admin staff)

    the admin staff and student common are quite restricted and are manageable.

    Staff common on the other hand has become a dumping ground for resources and even though i have the space on our file server. I cant identify whats important and non-critical when doing backups.

    backups have now become a problem because i can only max out 50gb on a tape. we have nearside backup but i would prefer to keep off site backups of this but cannot because the backup fails to says the tape is full.

    I spoken to the head about this and he's agreed I need to do something about this and was wondering what other network managers do to manage these often larger by the day shared areas. all these areas are restruicted by department but we find that all departments are doing is just dumping everything on their shared areas. I know for a fact that a lot of the imformation is redundant but am afraid to delete it.

    Does anyone have an ideas what I could implement. I thinking of having department meetings to discuss this with every department and try to make them understand and see what they say if i delete staff common and start over.

    anything is much appreciated.

    One server won't backup as it's just over the 50GB tape limit, so we're planning to move all shared folders to another NAS, which in turn will be backed up to our backup server. All in all, our curriculum (staff+pupil) shared documents account for about ~17GB of data.

    Tapes suck. External USB drives or a full blown backup server is the way to go.

    If you need to limit disk usage by users for one reason or another, consider implementing quotas.

    We are (very slowly...) getting staff to move educational resources that they have prepared to moodle VLE so they are more structured and accessible. We've pretty much banned applications from staff areas and home drives, hopefully all that will left will be some admin stuff. Easier said than done without quotoring upload limits to shared areas.

    Re: Shared areas on school networks

    Further to what Ranj said we are looking at investing in a new backup server for a 3 to 5 year plan and dumping the tapes for a mirrored cluster of NAS boxes using Raid 5. Assuming the maximum we could possibly need to backup in 3 years or so would be 800Gb (yes I did some guestimates) this should be easy.

    Anyone implemented similar and found problems/limitations with this set up?

    I dunno about NAS. There's a slight feeling "all eggs in one basket" about it. Sure, tapes do go wrong but I rather loose one tape then a massive NAS box.

    Even including the upfront costs of buying a tape drive, the price per gigabyte is probably more favourable if use Ulitrium or AIT3.

    You can avoid this issue if you use a SAN instead.

    do a weekly search for files... .bmp .mp3 etc and delete them.....

    that should nock the backups down a little

    And on that note, don't forget Administrator's Nasty File Search.

    WinDirStat is also useful for seeing where all the space has gone.

    Re: Shared areas on school networks

    The new 2003 R2 features allows you to compile a report on file usage. You can run an on demmand report or schedule it to run and it will email you. You can report on quotas, whos using the most space, what the biggest files are, duplicate files etc etc. You can also set it to email the user and/or admin when they reach their quota warning level or their limit etc and automatically email a report on that users usage.
    Upgrading to R2 is very easy as well. You only need do the schema update and one server if you wish. Takes about 10 mins to upgrade the server.
    All the admin is done through a management console as is nice and easy.

    Re: Shared areas on school networks

    LTO tape drives store a lot more Data on them than DDS tapes
    300/400 GB Native depending on what one you get.

    I have a Tape problem too i backup waekly to a HDD in another Server and use external HDDs for off site backups.. but you can span data across DDS tapes

    but looking to get a LTO drive in the next finacial year for the main file server.

    Re: Shared areas on school networks

    50GB is a pitiful amount of backup storage (it wouldn't even back up my staff areas!). Dos_Box and I both use Tanberg LTO2 Autoloaders and they work well - they do set you back £2.5K but in the grand scheme of things that's not too bad because if you load it up with 8 tapes you will get 2.5TB!

    Re: Shared areas on school networks

    We have external hard drives which backup:

    Currently I have set up each a 2 shared drives:
    -StudentResources
    -StaffResources

    Each has each subject/faculty that I have created and then its subdivided into KS3 and KS4 - and further subdivided into Academic Years and then year groups.

    So typically a student poetry resoruce for this year's yr7 would be:
    O:\Communications\English\KS3\05-06\Year7\Poetry.doc

    I know that it is long but its organised and not getting in mess like the old one. The same convention follows for StaffResources but these files cannot be seen by students.

    We also use access based enumeration therefore students can't see files which are not accessible to them!!
