It's a small volume (163Mb), but it locks for about 10 minutes... 
Shouldn't the lock be ONLY for the number of seconds it takes for
'vos backup' to finish?

That don't seem to happen on my system... OR, the lock while cloning
the volume isn't released when the volume is finished cloning...

Ah, so you can read (write?) on the volume, but it won't return until
the dump is finished?

Can this be surcumvented some how? When backing up the web volume,
I won't be able to server documents for about 10-15 minutes!
