Can I exclude /run from my backup scheme?

view story

http://unix.stackexchange.com – I have written a rsync-based system backup for my Linux system. The aim is to be able to redeploy the system entirely from the saves, so I don't only backup homedirs. I have excluded a few top-level directories from the backup: /proc, /sys, /mnt, /tmp. I wonder whether I can exclude /run and still be able to get a viable save? I observe that it takes a lot of disk space on my backup disk (mostly with /run/shm). (HowTos)
