Big change :
-> systemd-nspawn usage instead of chroot
-> Folder directory structure changes

Before : /backup/jails/JAIL_NAME/ <- RootFS of chroot jail
Now :
-  /backup/jails/JAIL_NAME/rootfs <- Jail rootfs (ro)
-  /backup/jails/JAIL_NAME/var <- Jail /var (rw)
-  /backup/jails/JAIL_NAME/data <- Jail /data (rw)

New dependencies :
- systemd-nspawn (package systemd-container on Debian)
- check_ssh (package monitoring-plugins-basic on Debian

Still a Work In Progress.
As of now, it won't work on existing servers as the jail folders needs
to be converted to the new folder structure
