Backup infrastructure
Our backup infrastructure leverages zfs send/receive functionnality via syncoid from the sanoid package. We use a custom script called bacoid, which gets its config files via zfs config. Backups are sent to two PBS servers that are in lxc containers.
How to integrate server
Syncoid sends incremental backups via ssh, thus we need to make sure we can ssh to the backup server.
On the production server:
$ ssh-keygen $ zfs set syncoid:target_a=$user@pbs-koma.ayakael.net:55200 rpool $ zfs set syncoid:target_b=$user@pbs-veita.ayakael.net:55200 rpool $ zfs set syncoid:machine=$machine_name rpool $ zfs set syncoid:pool_a=data/pbs rpool $ zfs set syncoid:pool_b=data/pbs rpool
On the PBS server
$ useradd $user $ mkdir /home/$user/.ssh $ vim /home/$user.ssh/authorized_keys $ chown -R $user /home/$user $ zfs allow -u $guid clone,create,destroy,mount,receive,rollback,send,snapshot data/pbs/$user
Then you can run bacoid
