Data Recovery

    I have a Iomega Power Pro (2TB external hard drive) which has Raid 5 set up.

    I use it for my music, photos and dvds.

    I stupidly deleted my aperture library from it and my back up on another external hard drive is old.

    I thought everything was safe as i was using Raid and everything was getting backed up.

    Does anyone know -

    can i restore the files via raid or

    can i recover the files using software and if so which software is recommended (data rescue II, data recovery etc)

    ive disconnected my power pro while i try to sort this out.

    also does anyone have recommendations for future prevention of the same happening again (apart from not being as stupid).

    any advice for recovery would be greatly appreciated

    RAID is designed to protect from drive failures, not from manual deletions unfortunately.

    I don't know how tools like DataRescue or FileSalvage (very good tool) will work with a raid array. Should work ok, but i'm not sure. Depending on whether the blocks have been overwritten or not you may or may not be able to recover the files. Good thinking in disconnecting the array - you're preventing unnecessary overwrites right there. I guess, run the software and see!

    Future suggestions - well you could always use TimeMachine, or TimeCapsule if you want a hardware solution.

    it comes down to the fact that the RAID array, if you're using it as primary storage, can only protect you against drive failure in the array. The ideal set-up would be to use a different bog standard USB drive as you primary storage and to use the RAID array as a TimeMachine drive.... That way, if your primary storage fails (or you make a mess of something) you can pull the time-coded backup from your fault tolerant RAID array.
