Interrupted backups are usually saved as "partial" backups.  Rsync will 
start synchronizing and only transfer what needs to be transferred, 
though it will always start comparisons from the beginning.

If a connection is merely interrupted, the shadow copy will persist in 
the background -- a new backup will start a new shadow copy which may 
fail (depending on available space and the OS, though it's possible to 
have multiple simultaneous shadow copies.)  Rebooting or shutting down 
the system will remove all shadow copies.
