If he is concerned about data loss I'd grab an external USB drive and rsync the data between the Drobo and the external to have a backup copy in case things do not go well during the rebuild.<br>

If the array is toast then you're most likely looking at some sort of professional recovery service unless Drobo support has suggestions on how to get the array back online read-only to recover the data.<br></blockquote>

One thing to always keep in mind: RAID is not a backup. I've had to state this too many times recently. While it prevents data loss from a disk failure (or multiple failures) it is not an excuse not to have a good backup.<br>

Does anyone have experience recovering data from a Drobo storage device? <br>
<br>
A friend's Drobo device is dying, one of the drives is likely on its<br>
last legs and he's looking to get his data off of it. <br>
<br>
I haven't done anything with Raid, and from Drobo marketing online I<br>
can't tell if their "BeyondRaid" is real Raid or not. <br>
<br>
If the Drobo is real Raid, what information would I need to get to<br>
figure out the next steps to recovering the data off of a good drive? <br>
