Hello everybody,

I hope to receive comments about this because I do not think I'm the only one having this type of need.

I'll be surprised if you get a lot of "ME TOO" replies.  But who knows.


One thought I had might be possible with no changes to amanda.

Lots of one-off requirements are satisfied with "wrappers" for the
standard amanda commands.  For example, people who want to encrypt
their backups substitute their "tar" command with a shell script
that calls the same tar in a pipe with an encryption program.
Consideration has to be given when writing the wrapper whether it
is being called during an estimate phase, an actual dump, or a restore.

What I'm wondering if if you could "wrap" the planner program, or some
part of the estimate phase.  Let it capture the results and take action.
Perhaps based on some lookup table.  Eg. if the result is for /x/foo,
then use these values to make further decisions.  If all is ok, then
pass the planner results to the next amanda component as if the planner
were run without the wrapper.  IIRC, the planner output was pretty simple.
