Just how large a file system does this need testing on? - I run it on 2 x
9Gig UFS systems and one 12Gig UFS filesystem - and it's not failed yet
(Typically the file systems are at around 70% capacity when running dump).

If dump/restore really is broken - I'd kinda like to know now, although the
results of our last disaster recovery test (i.e. take a blank machine and 2
tapes) were successful...

The only time I've seen problems with dump/restore was with a dodgy SCSI
bus, in which case the dump would work fine - but the restore would either
claim the tape was "not a dump tape", or it would core dump/panic at varying
parts into the restore... Fixing the termination on the bus fixed this
though - and it has been thoroughly tested...
