That is an excellent document! I'm sorry that I bothered the list
before finding and reading it . . .

Will this persist across power cycles? Will previously hardware
compressed tapes turn hardware compression back on?

Yep.
No argument about it.
But, I don't keep index files along with the backup image on tape.
Before running amrecover,
I would run a script to

How do you recover an amanda dump file without amrestore? I had dd'd
one to disk and tried to untar it but got the message "not a tar
file". Once I ran it through amrestore I was able to untar it
though.

restoring w/o amrestore can be done with dd, gzip, tar, and so on, way
messy compared to amrecover (or amrestore) but its possible. That's one
of the plus's to amanda.

Assuming you're running Linux, all you need is some form of Linux
rescue disk. I've got a bunch of Debian installer cd's lying around
and have used them for similar purposes before. Probably most Linux
installer cd's can be used like this, and I'm quite certain
something like Knoppix would include

... or just write a couple of copies of a CD with gzip and whatever else
you might need.

True. But one can work around that by backing up / uncompressed,

If you don't believe me, try to zip a gzip file. See if it gets any smaller.

Yes, I am learning -- at the expense of many questions ;>
First, a brief overview:
I have five (5) Linux servers, totaling ~50 Gb used diskspace, divided
roughly even across all five.
I have several DAT tape drives, the largest of which is an HP DDS-3. I
have twelve (12) DDS-3 tapes, and twenty
