+# 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 serves that are in an lxc container. 
+
+## 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/ovh data/pbs rpool
+$ zfs set syncoid:pool_b data/ovh 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
