Well, if the laptop's down, none of these methods will help you back it
up, obviously, but here's a brief outline of the pros and cons:

* automount of shared directories + rsync (what I do now).
Probably the least bandwidth-efficient, since rsync has to read every file
over the mount.  Can't handle open files.
* smb
Requires the least amount of software on the client.  Uses timestamp for
incrementals, so can miss copied files and renamed directories during
incrementals.  Can't handle open files.
* automount of shared directories + tar
All the disadvantages of mounting plus all the disadvantages of tar
* rsyncd/rsync
Can be bandwidth efficient and seamless, there are scripts publicly
available that can handle open files.  Within this category, the
variations of ssh/rsyncd, rsyncd, winexe/rsync have varying degrees of
speed, ease of deployment, and encryption.  I use the winexe/rsync method
since we have no need of encryption, so we prioritize speed and ease of
deployment.

* Other ?
