 bkctld helps you manage the receiving side of a backup infrastructure.

 With bkctld you can have hundreds of jails, one for each client to push its data (using Rsync/SFTP). Each client can only see its own data.

-Since the client connects to the backup server with root, it can mess with the jail and destroy the data. But the timestamped copies are out of reach because outside of the chroot.
+The client obviously has access to its uploaded data (in the chroot), but the timestamped copies are outside the chroot, to reduce the risk of complete backup erasure from a compromised client.
 
 It means that **if the client server is compromised**, an attacker can destroy the latest copy of the backed up data, but not the timestamped copies.
 And **if the backup server is compromised** an attacker has complete access to all the backup data (inside and outside the jails), but they don't have any access to the client.
