Agreed.  I've had that happen on tape-to-tape clone as well (7.2.1), and I did 
a per-SSID clone for-loop until I hit the one that bombed.  My choices then 
were to groom my SSID list daily until I got past my check point (normally the 
process looks at $POOL in '4 weeks ago' with copy<2)....or delete the offending 
SSID.  I've done both.  The second is easier, but not always an option.

No, I can't see them there: all the savesets that are missing are from
around the time we had an array crash and restart so I'm suspecting
it's a storage problem.  But I'll watch out for the scenario you
describe: it rings bells for other problems.

Failing ~300 savesets because one of them is unreadable is a bit
naughty, too.

Sounds worth getting the patched versions anyway, though.

Thanks for your input.
