    I'm looking at the best way to maintain/back up my office computer which has
    my alarm downloading and alarm management applications running on it, I
    mention that so that the post won't be entirely off topic.

    Anyway I have a RAID 1 (mirrored) with a pair of 500gb hard drives and a 2
    port controller card by 3ware.

    My thoughts are to either to have one of the drives of the array in a
    removable tray and on a regular basis remove this drive, probably once a
    week, cycle another tray/drive into the array and then rebuild the array.
    This should ensure that in the event of a virus or corruption of some sort,
    I will only lose, at worst a weeks worth of data which I could live with.
    Any failure of a single drive being taken care of by the RAID.

    Alternatively I could have the two drives of the array permanently installed
    and use a disk imaging back up, probably by Terrabyte, to image the array to
    the third disk in the removable tray on a regular basis, again probably once
    a week.

    What are the advantages/disadvantages of either method

    There's this nifty little drive from Seagate (I don't usually sell their
    stuff, but they sent me one to try out). It's at

    It comes complete with easy to configure software (for scheduled
    backups), or you can "backup on the fly". :)

    I use a 500GB Maxtor One Touch III. I have it automatically update
    changed and added files on a daily basis. It works off my USB port
    seemlessly in the background. You can also use it as a spare drive. This
    drive comes in many sizes and is also available in 1+ Terabyte.

    I have been thinking of subscribing to one of those off-site services, and
    schedule automatic backups over the internet. Just wonder how secure they

    The NAS options out there are pretty slick these days...a few hundred bucks
    for lots of redundant RAID storage, managed, and super-easy setup. We have a
    fancy one here at the office and we've lost a couple drives (in the NAS
    itself) over the years, but have yet to lose a single byte of data through
    the drive failures. Expensive, but worry free. Also, it doesn't give you an
    off-site backup.

    The Terabyte (Image for Windows) approach is a nice secondary allowing you
    an offsite option that can be recovered very quickly. IfW can make DVDs
    directly, which is a nice option. You gotta remember to do the work,

    It depends on how determined someone else is to hurt you. We've seen
    here that you are not above anything. Now imagine if someone had
    access to your personal information and had your lack of morals.

    I've installed several of those "FreeAgent" external drives now, as
    additional storage for DVRs that don't have room for more internal
    drives. They install easily and work well, as Frank says, and they're
    dirt cheap - CDN$100 for a 250GB. At that price, you could have two or
    three and cycle them through for backup duties, keeping one offsite if
    so desired.

    Or, was a vindictive nasty son of a bitch like you are, who justly
    deserves someone finally getting even with you.
