Hum... Vaguely resembles CPM Disk dump... I could be wrong, since last time I used CPM was... 1982ish...

Looks like a backup of some floppy media of an old school OS... maybe...

One trick you can use is to dump the entire tape using tar, basically telling tar to ingest the entire tape, breaking each EOF marker into a separate file, ending when EOT is hit.

1980s was last time I even saw a mag tape, so this is all from memory.

Best to dump all the tape data to disk, then work on the disk files.

Best, meaning, you'll likely spend a good bit of time pulling your hair out trying to understand data while it's on tape media.

Hi David,

I have already performed a dump via Linux, that is what we are looking at.  I can recover files in a forensic format to some extent. The tape was made in 2003. It does not look as if NTbackup made it the MTF begins with TAPE, and it does not have a Veritas header.

2003... The format sure looks like some very old OS. The H: looks vaguely Microsoft-ish.

The \\FSERV2 looks like some other OS, without camel case support.

Whew... If the output you provided really is the first tape block + you get no read errors (indicating first block is corrupted), it's unclear.

No search I did turns up any listing of backup tape format which looks like your first block.

Good luck. Looks like decoding this tape may be a long process.

Thanks David,
It does look odd!

I do believe this was a Microsoft based server and the tape also backed up a network share. I can see standard MS directory hierarchy at text in the images.

Can do that dump but in hex it might make more sense

I disagree, CAROOT implies ARCSERVE, no ifs or buts on that score.

Marked my answer as best, since it covers generic tape dumping + debugging, which seems to be required to resolve this issue.
