Jon,

Thank you, I was very worried about that.

Looking at the temp files in amanda work I see that I take
to be confirmation that we are not running the DLE through
zip since I'd have expected an additional pipe here.

Is that correct ?

> more wcnotes._maildb2_five.0.3.tmp
AMANDA: CONT_FILE 20070522 wcnotes /maildb2/five lev 0 comp N program /usr/local
/bin/gtar
To restore, position tape at start of file and run:
        dd if=<tape> bs=32k skip=1 | /usr/local/bin/gtar -f... -

When I tried a restore yesterday I found that the files I brought
back had a long numeric number preceeding the original path. I will
try a restore again when the current amdump run completes to see if
this is still the case. Is this normal, or perhaps an artifact of
not having a proper/correct verion gtar ?

Why is the version of gtar so important ? I noted in at amanda.org
yesterday that at least one of the versions formatted gtar -t
differently and caused problems in amrecover. As we have habbitually
used amrestore that is likely a non-issue for our site (though we
should learn to use amrecover as we have many cross-platform large-DLE
restores at our site). 

                                                thank you,

                                                Brian
