By specifying "user@address:path" you are telling rsync to copy the files ot a 
remote machine - that's how the backup gets to the other machine.
To make it bootable, you'll need to arrange that the root of the remote path is 
the root of it's own filesystem, then you can do some stuff with chroot and 
install grub on the appropriate disk.

I don't normally bother trying to keep backups bootable. I'll just prepare a 
system to restore to, create the filesystems, create the mointpoints and mount 
all the filesystems, and then rsync all the files back. This can be done while 
booted from a "live-CD" environment - or for virtual machines, by mounting the 
filesystems on the host (but be careful not to restore your backup to the wrong 
place and wipe the host filesystem, it's "inconvenient" !)

NB - please keep replies to the list.

Rats, yes you *must* specify numeric-ids or the backup is usually "a bit 
broken" as ownership information will get mangled.

Yeah, that's a bit "6 of one, half a dozen of the other".
I prefer to have a backup that is a complete image of the source directory tree 
- rather than several backups, one per filesystem. You can do the former while 
doing "one sync per filesystem", but you have to be a bit clever with your 
excludes to avoid the sync of the root deleting all the other filesystems 
before the next step puts them back again.
And I sometimes re-arrange my volumes during a restore - and then it's easier 
to have one backup tree rather than one per filesystem.
