I've been through this but still don't have it working.  On the

It sounds counter intuitive, but you may need to check the version of
the AMANDA *client* supports "server-side" encryption.  You probably
need 2.5.1 or above.

I was confused by this, initially, thinking "why does the client need to
support encryption when I'm doing the encryption server-side?".
Apparently, from reading the source code, my understanding is that
AMANDA tries to figure out which facilities are supported by the client
and bombs out as above in those circumstances.

I'm just wondering whether this is a bug in AMANDA, or whether there is
a good reason for AMANDA to insist that the client 'supports'
server-side encryption ... ?

Wow, that did indeed clear the error from amcheck. I haven't run amdump yet but I'm optimistic it will run now that amcheck is clearing it for encryption.

I think an alternate informational message would help, or at least better documentation on the requirement for using encryption. I wonder what the client requirement check is for, perhaps it's a vestige of a previous encryption framework?
