How do I make a verified backup to disk?

The software can have a licence installed for a Disk and Tape Offloader feature. This feature manages copying files from the Codex VFS to up to 2 disk and 2 tape (LTFS) targets simultaneously, and performs a byte for byte verification immediately after the copy.  It also writes .md5 checksums with the files to allow for verification of subsequent copies, and provides comprehensive logging features for each offload.
