I use both full and virtual fulls as well. I have laptops that are hit 
or miss on completing their real full, so I too run a virtual full on 
everything to get a set of jobs that (at the time) require no 
incrementals and are written to USB drives. At that point, the volume 
files on those USB devices are copied to another set of USB drives along 
with a text dump of the catalog, and the second set is taken offsite. I 
use 3 sets of USB drives rotated through connected, onsite firesafe, and 
offsite location. Some will not be allowed to use this method due to the 
disk-to-disk copy, but it does keep the catalog consistent with 
available onsite media for restores. The offsite drives are for 
emergency use only, since they require restoring the catalog from the 
text dump.
