I tried a bare metal recovery yesterday, but without the success I had hoped
for. I restored the latest level 0 dump and then tried to restore the
incremental dump over it. First step worked like a charm, but as soon as I
restored the incremental tape, I got the error:
"restore: Incremental tape too low"
Amdump uses "dump" to make dumps, so I use "restore" to put them back.
Here's what I did. First, I checked which tapes I needed:
amadmin Dagelijks info xxxxxxx /
"Dagelijks" is my daily set, incremental. Amanda gave me the following list:
-----
Current info for xxxxxxx.xxxxxxx.xx /:
Stats: dump rates (kps), Full: 7283.0, 2961.0, -1.0
Incremental: 2635.0, 2577.0, 2358.0
compressed size, Full: -100.0%,-100.0%,-100.0%
Incremental: -100.0%,-100.0%,-100.0%
Dumps: lev datestmp tape file origK compK secs
0 20040416 Dagtape-04 22 1318285 2636570 362

(I replayed yesterday's scenario today, so the dates are rather recent)
You didn't mention the version of amanda on the server.
It used to be (pre-2.4.3 I believe, not sure) that "info" listed
all incremental levels, even those that were older than the level
minus one.
So it could have listed:
> Dumps: lev datestmp tape file origK compK secs
> 0 20040416 Dagtape-04 22 1318285 2636570 362
> 1 20040415 Dagtape-02 19 67215 134430 51
Notice the datestmp on the level 1. That level 1 is not needed
for restores, but older amanda versions did list them.
20040416 was last friday, and if you had the problem in the weekend,
the incremental backup from the weekend did not succeed, and the old
amanda version would have listed the not-useful tape from the previous
incremental.
Did you get the same message with the replayed scenario? Or are the
error messages from the real restore on monday only?
