I'm pretty sure I used a backup tool back in the eighties which would write something that ''could'' have been that format, but if that would have been considered a part of the backup-system suite I'm not so sure about. The format is basically as follows: Each volume file has an 8-page (16K) header with a dir name and a label, a volume number and the total number of volumes, and a list of page numbers which tells where each of the 2KB pages following the header should be written. Plus a little extra metadata. A feature of the format is that you could take any of the volume files in any sequence and simply update the output image, when all the volumes have been applied you have a disk image in ND format. --[[User:TArntsen\|TArntsen]] ([[User talk:TArntsen\|talk]]) 16:39, 20 May 2020 (UTC)		:::Hopefully you received the decoded images - unless they were too large for the mailbox.

	Nice! It's good to see this documented. I wrote a Unix tool to read backup-system format CCTs back in 1998, specifically for IRIX on an SGI system I used for reading my old ND backup CCTs. I'll read through the description to see if it all matches what I did, or not.. a quick check looks very familiar. Thanks for adding the page. -- [[User:TArntsen\|TArntsen]] ([[User talk:TArntsen\|talk]]) 11:09, 19 May 2020 (UTC)		Nice! It's good to see this documented.
