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...
