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

(I replayed yesterday's scenario today, so the dates are rather recent)
First question: do I get it right if I draw the conclusion that I need to
restore "Dagtape-04" first (being the level 0 dump) and "Dagtape-02" after
that?
I thought I did, so I inserted "Dagtape-04", booted the machine to be
restored off a Knoppix CD, made the partition to which I wanted to restore
pristine (love that word!), cd'ed into it and ran:
amrestore -p /dev/nst0 xxxxxxx /" | restore rf -
over SSH. So far, so good: everything gets restored nicely. Now for the
incremental. I inserted "Dagtape-02" and ran the same amrestore command. As
soon as restore gets to the incremental image Amanda feeds it, it says:
restore: Incremental tape too low
According to restore's manual, this is the way to do a restore and since
Amanda doesn't complain, I assume it's me who does something wrong. For
what I understand, "Dagtape-02" (made only tonight) is the latest
incremental tape there is, so how can restore complain that it's too low a
level?
Any suggestions?
Thanks in advance,
Hans
