According to the manual the -x option is:

-x, --one-file-system       don't cross filesystem boundaries

I use that option all the time to keep from backing up my large home directory 
when I only want the system directories under root.  It even keeps rsync from 
copying system directories like /proc /dev and /sys.

Before I do a system update/upgrade I run rsnapshot (debian package) on the root 
system directories so I can get the system back in case of major failure in some 
of the updates (I run testing so I have to be careful).  I do run this on a live 
system and on 3 or 4 occasions I have had to restore from the snapshot 
successfully getting my system back alive.

Do you have another system you could backup to?  I can get around 50 mega bytes 
per second transfer over 1Gb Ethernet so you might try that.

My main backup is done by backuppc on a dedicated server .  I have 4 or 5 
systems that get unattended daily backups with versions going back about a 
year.  All my systems use a 2 drive raid1  array so I can survive a single disk 
crash without having to resort to restoring a backup.  Every few months I 
install an extra drive in the backuppc server and have raid sync it to the 2 
drives in the server.  After syncing I pull the drive and put it in my barn for 
offsite storage.  Since it is a raid1 full copy you can take that drive and 
mount it on another system and get the files back if you need to (running the 
raid array in a degraded mode).
