I manage another rsync-based disk-to-disk backup program, dirvish (www.dirvish.org, originally written by jw schultz). Rsnapshot and dirvish and most other backup programs use server pull for a number of sensible reasons: 1) Security: Backup clients can be compromised, and should have no ability to initiate reads or writes to the server. 2) Network load management: A backup server can coordinate and sequence multiple backups much better than clients can. 3) Disk management: A backup server should manage its own disks. You can achieve the functional equivalent of client-initiated backup by signalling from the client to the server that backups should happen, or flag a file on the client that is polled by the server. You can write simple scripts to do that for dirvish or for rsnapshot. But after that, the server should control the process. Since an important reason to do backups is to survive security penetration, bypassing these protections reduces the value of backups.
