Wow, it's amazing how much data is caught up in retries.  On one of our
larger instances, the amount transferred is 2.8TB but only 1.3TB was a
part of the storage pool backup!
Are retries the only explanation of this?

Shawn

One commonly encountered reason is retries, evidenced in the full
client log.  (It's a product deficiency that the summary statistics
don't report the retries in any way, so you have to pore over the full
log.)
