Amanda users,

I may have missed it in the mailing list... I know that
encryption came available in 2.5.0, either server side
or client side, or the channel (though I think encrypting
on the client provides an encrypted channel by default, true ?)

Anyway, I was wondering and haven't seen... how to encryption
and compression play against one another. Some data compresses
very well, some doesn't, If you are encrypting, doesn't that
tend to cause the data to be less compressable ?

We are looking an encryption on the tape for one of our amanda
servers, just want to sort of know what to expect when I upgrade
the client and server and turn on encryption, compression is
already enabled.

                                                thanks,

                                                Brian
