Amanda 2.5 uses the same protocol as 2.4.  One can use a 2.5 server with 2.4 clients and a 2.4 server with 2.5 clients.
 
To restore a dump created with the tapesplit_size option using amrecover,
you need a 2.5 server + 2.5 client.  (Extracting that backup using
only shell, mt and dd is also possible.)

* Both authentication and encryption?

Compatibility

See amanda-compatibility(7) for the most up-to-date information about compatibility between Amanda versions.

Upgrading

The recommended course for upgrades is to upgrade the server to 2.5 first, and test backups and restores before upgrading clients. Both upgrades should be seamless, although you may wish to adjust your server configuration to account for new features like tape spanning.
