Not any more, but I did in 1995 or thereabouts :-) 486-DX33 (or
was it a DX2/66?) with 16 whole megabytes worth of 30-pin SIMMs.
It turned out that (a) that wasn't enough RAM, and (b) FreeBSD
2.0.5's low-memory robustness left a fair amount to be desired,
as I discovered a few times when I came in in the morning to find
the backup server down, and the /var partition, where the holding
disk was, thoroughly trashed.
(It also turns out that FreeBSD still supports the *3*86 -- last
month's 4.9 release contains a bug fix for it. I imagine Linux
still does too. Both are equally gratifying...)
I think the Amanda version was 2.2.6 -- just saw that mentioned
near the beginning of the ChangLog, and it rings a bell.
Interesting limitations (some from memory, some from ChangeLog;
some probably incorrect):
- No changer support. One tape per run; that's it, that's all.
- No indexing, no amrecover. Amrestore would pull dumps off
the tape, but from there you were strictly on your own.
- No gnutar; it was strictly dump.
- No "reserve". Effectively, it was hard-wired to 100%.
- No "runspercycle".
- No chunked dumps on holding disk.
- No promote_hills() in the planner. If you missed a tape
(e.g. for a holiday), causing that night's full dumps to be
postponed, they'd have a strong tendency to stay clumped
together with the next night's full dumps for a long time, at
least on a small network like the one I was responsible for.
- Blair Zajac's extensive patch set hadn't yet been merged into
the canonical sources. If you wanted them, you had to
download and apply them yourself.
I don't believe Jean-Louis was involved yet (from the ChangeLog,
runspercycle and chunked dumps were among his early patches); I'm
not even sure that (the long-departed) Alexandre Oliva and John
R. Jackson were around back then.
Truth be told, I think Amanda was rather moribund at the time
(hence the existence of BZ's patches in the first place); ISTR
that it was Alexandre who woke the project up again.

It must be said that they would have sounded better if the singer
wouldn't throw his fellow band members to the ground and toss the
drum kit around during songs.
