Can't create a backup of VM because 2 drives combined are 2tb

I have 3 ESXI hosts and V-center Server, each having 2tb (max) datastores. My File server lives on one. the file server has 2 virtual hdds one on the primary datastore of esxi 1 and the other on the secondary datastore. When I create a clone of the file server to esxi 2 where i keep copies of all my servers it always tries to put the 2 virtual drives on the same datastore but there is insufficient space since the limit is 2tb (1.87tb) usable. Snap shots always go to the same file location as the server I am backing up. because that location is rapidly filling up and the chance of any one server failing, I want my backups in another location. does any one have a good backup solution for a server that is 2tb. even if I could just get a clone of the one virtual hdd and leave the mirror behind would be fine to.

You can build datastores of more than 2tb, using extents, or use a NFS datastore, whiuch can exceed 2tb.

yes, you can create a vmfs volume max of 64tb using 32 2tb vmfs datastores.

or you could upgrade to ESXi 5.0, which has no 2tb limit.

Really I was not aware they had the new ESXI out That's awesome. Is there major down time in an upgrade?
