I always restore on the server, then transfer files to the clients. That
clearly works. I can see that if you need to be able to run amrecover
directly on the clients there are more potential problems with old
versions. Note, though, that even if the amanda configuration is totally
broken, it is always POSSIBLE to restore just using dd and tar or dump.
Maybe not convenient, though. You never want to get to that stage if you
can avoid it.
