I have a Mac and I use TimeMachine to backup it up to WHS. I installed WHS connector on Mac and created share on WHS called MAC with folder duplication set o "OFF". Within that share I created Mac "hard disk" using connector so it can be used by MAC TimeMachine. My MAC fully loaded uses 120GB so I set MAC backup disk to 150GB. I was able to backup my MAC ok but I'm getting this error on WHS:

Duplication is falling for shared folder: Mac. There is not enough free space available to maintain a copy on more than one hard drive.

My WHS has about 400GB free space left and I have turned OFF folder duplication for MAC share so I assumed this duplication refers to actual MAC backup hard drive that was created by WHS connector. How can I turn that off? I don't want to created like 300GB disk for backups.

I don't know anything about Time Machine, but I have a feeling its creating one large 150GB file? Then WHS is trying to find a hard drive that can store the whole file.

As WHS does not break up files to multiple drives, do you have any individual drive with enough room? You may need to remove a disk from your storage pool to clear it of data, before readding it to the storage pool and letting WHS rebalance.

I haven't thought about it that way and you might be on to something because as of this morning my error disappeared and I will take a guess in accordance to what you suggested that WHS was able to do "Storage Balance" and move the data around.
