Adding a client, FreeBSD

Client side

• Execute:

pkg install amanda-client
pw usermod amanda -s /bin/sh

• Install ~amanda/.ssh/authorized_keys

Server side

• Add the host key to ~amanda/.ssh/known_hosts:

su -m amanda -c 'ssh -o StrictHostKeyChecking=no foo.example.com echo ok'

• Add the client to /usr/local/etc/amanda/daily/disklist.
• Check config:

su -m amanda -c 'amcheck daily'

Adding a client, Windows

• Download and install http://www.zmanda.com/download-amanda.php
• Unless you've changed FreeBSD's username from amada to amandabackup, use regedit to set HKEY_LOCAL_MACHINE\SOFTWARE\zmanda\zwc\1.0\Install\backupUser = amanda.

Notes

On FreeBSD, Amanda's variable files are scattered far and wide. They are stored in:

• /var/db/amanda (this is ~amanda)
• /var/lib/amanda
• /usr/local/var/amanda

Quick password generator:

tr -dc A-Za-z0-9 < /dev/urandom | head -c32;echo
