    Backup server hardware

    Hi guys,

    I am trying to build back up server (debian linux as OS) for my school administration workstation computers (we have 3 admin computers).
    So my question is if I would like to transfer files (around 1 GB/month) as backup from workstation (windows) computer to back up server (linux), should I upgrade the memory RAM or the hard drive server?

    At the moment I have only 1 GB for memory and 150 GB hard drive, I have to choose betwen memory card and hard drive... ( we don't have enough money to upgrade both hardware).

    So any suggestions..should I go for memory card first...or hard drive first..?

    I am assuming that by "backup" you mean storage, rather than a functional backup.

    You have 150Gb of storage, and you want to transfer 1Gb/Month?

    Allowing for 20% redundancy on the hard drive (they tend to work better if they don't go above 80% of capacity) you have storage for 10 year's data...............the machine will surely have been replaced by then?

    For simple data copying tasks 1Gb of RAM is more than adequate. I would be very surprised if you even used the first 512Mb.

    So, on the face of it, the answer to your question is probably neither.

    However, as this is a backup server, you might consider another hard drive and going for a RAID1 array (mirrored). That would give you greater security.

    Ahh you right about that, it's storage. We will transfer files as back up in that storage only for 1 month and then when we'll delete it for the next "new month" coming up.
    OK this is the scenario... storage july files >>> on the last day of august, we will delete last july files back up/storage>> back up/storage august files and on last day of sept, we will delete last august files..and so on.

    Thanks for the suggestion for that RAID! array (mirrored), any howto raid array mirrored the easy one?

    This might help:


    Otherwise just do a google search for "RAID ARRAY" then search for Debian in the results. There are lots of articles so you need something that matches your hardware? that would be the drives and the motherboard.

    Basically, there are two types of controllers: hardware and software...........hardware are generally considered to be the better option although both will work just fine.

    How important is this data? You think monthly is often enough?

    I backup my important data every night and send it offsite the next day.
    On machines that may not be *that* important... I do it twice/week.

    Are you going to store the backups offsite?

    Maybe you should look into some tape solution?
    Even burn to DVD?
    Even flash storage is cheap enough.

    1gig is nothing. I don't see a need for a server just for that...

    Is all the data actually stored on the workstations? If so, wouldn't putting it on a file server that is backed up on a regular basis make more sense? (Even burning the backup to DVD.)
    Quitmzilla is a firefox extension that gives you stats on how long you have quit smoking, how much money you\'ve saved, how much you haven\'t smoked and recent milestones. Very helpful for people who quit smoking and used to smoke at their computers... Helps out with the urges.

    Hey Hey,

    Both nihil and phish have offered great advice...

    If you want a true "backup" server you'll want to go with something more than a 150GB HDD... even in just a storage server you'll want more than that... nihil suggested mirroring... For once a month storage that's a great option... some others for daily storage/regular backup you may want include raid 10/0+1, raid 5, raid 15/5+1.

    What phish said makes even more sense... if you're looking at 1GB/month... why not CDs... the last place I was at we did regular DVD storage and saved it all... had a huge library... burn it to CD, date it, label it with the contents and update a database (access, web-based, whatever) with what CD has what on it... make two copies of each... keep one on site for easy access and store a second in an offsite location..
