(Dmitry Brant, Apr 2022)

Recently I came across a backup tape (an AIT-3 100GB tape) that was written with a format
I didn't recognize. The only thing I knew is that it came from a Mac workstation, which means
it was likely written using Retrospect, which was a popular backup tool at the time.
This is the result of my reverse-engineering effort to get the contents out of this archive.
------------------

This backup format is composed of a sequence of blocks which use FourCC-style formatting.
(All data is big-endian. Dates are formatted as seconds since Jan 1 1904.)
