Ouch! Is that really the case?

<plug> ORBiT's Backup+ </plug> also does parallel backups and restores,
and I'm pretty sure the others do too.

As far as the disk space comment above, we do it differently - we do
purge the file in the process of doing the restore because "in the
old days" because of the cost of disk, it was possible that large
files couldn't be restored if enough disk space weren't available.
This more applied to databases where it was an "all or nothing"
proposition with ;DBRESTORE.

Thinking more to the 6.5 days, that may become the case again with
large files (but disk is becomming quite cheap and more dense).
