I posted last week that my confusion had arisen out of the "skip=1", having
located the required archive. The need to rewind and skip 2 files in this
case could have been avoided at step 1 above. Now *that* would make a
difference.
Ah, there is the confusion!
The "skip=1" parameter of dd is not about skipping files, but skipping
blocks (of size bs=32k).
the "mt fsf 2" does the skipping of two files.
Each file on the amanda tapes is the (maybe compressed) tar/dump output
prepended with 32K bytes. The first 32 Kbytes contain the amanda
header for each file, describing the content. To extract the bytes
for tar/dump, just drop the first 32Kbytes of the file.
