Someone beat you to it :-). As of 2.4.5 you can add "--days NNN" after "tape" to get multiple days of data. Note that the output format is somewhat different: $ amadmin RCAC0 tape The next Amanda run should go onto tape P02003/RCAC0 or a new tape. tape P02004/RCAC0 or a new tape. $ amadmin RCAC0 tape --days 3 The next Amanda run should go onto tape P02003/RCAC0 or a new tape. tape P02004/RCAC0 or a new tape. The next Amanda run should go onto tape P02005/RCAC0 or a new tape. tape P02006/RCAC0 or a new tape. The next Amanda run should go onto tape P02007/RCAC0 or a new tape. tape P02008/RCAC0 or a new tape. >Scott... John R. Jackson, Senior Systems Analyst, Engineering Solutions, Inc
RE: amadmin extension
Interesting. I had not used that feature of amadmin before (ie. marking tapes to not be re-used). I guess it would also have to exclude those. I suppose if this was in amadmin then setting up a script to email the output would be easy enough. Scott.. Scott R.

This works unless you have some tapes set to no-reuse, in which case you want to grep them out first. You've reminded me of something we have, a little more complex than that: attached is the python script I wrote for our backup server that mails us (via the amanda user, so set up an alias) if we need to change tapes from the changer, offering potential tape labels and suggesting which slots they should be loaded into. (Note that this script also doesn't cater to no-reuse tapes :) Tested on Red Hat, running on an EL4 server, but should be compatible with python 1.5.2. -- Jamie Wilkinson Senior Systems Administrator Anchor Systems Hosting, Colocation, and Managed Servers

This works unless you have some tapes set to no-reuse, in which case you
want to grep them out first.
You've reminded me of something we have, a little more complex than
that: attached is the python script I wrote for our backup server that
mails us (via the amanda user, so set up an alias) if we need to change
tapes from the changer, offering potential tape labels and suggesting
which slots they should be loaded into.
(Note that this script also doesn't cater to no-reuse tapes :)
Tested on Red Hat, running on an EL4 server, but should be compatible
with python 1.5.2.
