So far the most commented wiki post I have is
Small Business Server 2003, 2008, 2011 – External Backup Drives Compatibility List – TechNet Articles – Home – TechNet Wiki:

If you’ve hit an external harddrive that doesn’t work as a backup unit. let us know or edit that page. It’s a wiki so you can add what has and has not worked for you!
For weeks I’ve been meaning to look for a thread / start a thread about offsite backup options with ol SBS2011 / Hyper-V.
I have a handful of offices that have multiple locations and could have a second server, especially if it was serving as offsite backup.
Ideally I’d like to leverage technologies already available in S2008R2 so as to involve as few 3rd party resources as possible.
A table like that is useful if and only if it lists the number of people who found out that a given drive did NOT work. That way you can see a general pattern of a drive not working for many people. Otherwise there are far to many variables of why it may not have worked.
