Are there any recommended practices for performing a defrag on large volume systems? I have heard that backing up the data, then restoring it is a method of doing it, but this seems cumbersome

To expand on this, your typical storage system has so many layers of indirection built into it already that it really barely matters whether your data is contiguous or not. It affects prefetching for synchronous I/O profiles and basically nothing else.

Would it make a difference if the system is a Windows 2008 R2 box with 2 MD1000's attached or would this generally apply to all systems?

They have 10 VMs setup on the root of the server, one of which is a medium to heavy load SQL server. They also have all of their users (100~) with roaming profiles and a couple of users who use GIS all day, which makes up the bulk of the data.

Being aligned is more important.

Databases allocated on a fresh ntfs filesystem will never benefit from a filesystem level defrag as the intelligence about dataplacement is in the database.

Trancient files are likeley to be created/deleted before the defrag even runs.

Perhaps if you do something retarded like mixing loads in one partition or single drive luns it might be worth the effort to defrag?

Nope, nothing like that. Excellent, thank you for the info.
