Hi Chris

Where would that go exactly, I am not an expert on building /compiling.
I'll give it a try.

I copied the files from a vmware esxi machine to another machine via NFS 
today
220Gb in total ( a virgin install of sbs 2003 ) and it tar gzipped to 
2.3Gb, of course
it only contained the OS and no user data.

All "bare Metal" backups solutions seem to cost in excess of $500. The 
big issue to me
is the delta blocking which box does well. But by taking a new snapshot 
each time
box will see this as a new file and back the whole thing up. Even with 
an uplink of
2M which you can get with ADSL2+ it will take too long.

Cheers Dave
