    Hello!

    I am trying to implement a backup/recovery plan for our small organization, which will backup about 100gb per night 5 nights a week.

    I would like to do the following:


    • Attach a NAS drive like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16822186025 to our ethernet switch
    • Unit has 4 500gb drives
    • configure them in 2 sets of 2 drives; mirrored RAID 1
    • Each one will hold appox. 1 week of our backups
    • So we backup for 2 weeks
    • take the first set of two drives out for safe storage
    • back up again for 2 weeks on remaining set
    • after 2 weeks, swap sets

    Will this work? can RAID 1 or 0+1 be configured this way? :confused:

    If not, Please offer any suggestions that may.

    All help greatly appreciated!

    Thanks,

    Lynne

    It looks like the RAID 0+1 would work with a swapping protocol (6 drives total) but I think a better way to do it would be use the default RAID 5 which would be a superior data backup method to RAID 0+1 (there's always a bit of "yikes!" whenever 0 is involved with backup even though that is in turn getting backed up) and then for offsite storage, get two 1 TB networked (or USB if used just as a copy over) externals and back up concurrently or copy the backup over from the RAID 5 at predefined intervals and swap those two single units.
