Sample Invocation

# rsyncplan rsyncplan-plus201.rollback.cloud

It will fire off one ssh connection and close to grab most recent directory list. Next it will call rsync. You're advised to setup a ssh config entry for the remote root shell. This allows passwordless login via ssh keys.

rsync --link-dest= strategy

We collect a ls -1d and parse present directories as --link-dest= args

Target server directory structure

• /backups
• /backups/machine-name/rootfs/YYYY-MM-DD_HHMMSS_NS

Server side (say the above with sshd, rsync) can use hardlinks with recent yyyy-mm-dd attempts to keep disk space use lower between different snapshots.
