    With Storage spaces you can dynamically ADD more volumes if you want to.
    How do you image an "aggregate" partition?

    Again, Backblaze proves that Hitachi drives are really good! I'm glad that I chose a 4TB Hitachi hard drive for my music collection.

    And I'm also a suscriber to Backblaze for my backups.

    Hi there

    You back it up in "Data Mode" - you can either back up as an "Entire Logical Volume" or do it in Data mode. In "Volume mode" Windows treats it as an entire Disc --you won't be able to back it up as an "Image" though when using programs like FREE MACRIUM in stand alone (boot) mode. Your Backup program will need to be able to handle this in DATA mode.

    The disadvantage is that currently you won't be able to do a "bare metal" recovery of the data space - that's not normally an issue since you can recover the OS via the "classical Imaging method" if you need to do a bare metal recovery and then from Windows run your backup software to recover the data.

    IMO since the "Aggregate partition" is DATA and not OS + pgms there is no point in "Imaging" an entire data space as a disk -- things like Music libraries don't change much so once they are backed up you only really need to do "Incrementals" or "Differentials" on this type of data.

    That's largely the problem with the FREE backup products --great for Imaging things like your OS but for this type of purpose a better commercial product is to be recommended --the decent backup programs are only about 45 - 50 USD in any case --usually a WELL WROTHWHILE investment - both in time (recovering from Windows failures etc) and saving data - which for a lot of people is MORE VALUABLE than their ENTIRE MACHINE !!!.

    Imagine re-ripping 2,000 CD's (or more) / finding old music from iTunes etc (to say nothing of music you might have got from "alternative sources". Same with photos, important scanned documents, office spreadsheets / presentations etc.

    Added -- If you create a bootable ACRONIS backup based on WINPE then Acronis WILL support data spaces as "Disks" so you can "image" them as "Disks" with the bootable version -- the standard bootable version based on Linux doesn't support storage spaces but can backup the disks sector by sector.

    Here's how to create the WINPE 4 version of Acronis 2014

    Seems unnecessarily painful.
    Unless you are about to run out of drive letters, you may as well just add another drive.

    I can see some benefit to a server having this ability assuming you can "hot plug" (Novell was one of the setups I studied in my Network course)

    As for the original topic ... Hard Drive Reliability. Not much is being said.
