rdiff-backup & list of files

If i want to backup only this files:
/var/dir/file1
/tmp/file2
/etc/file3.conf

It is possible to do it with one single line of code?

 

If it maybe helps: I wrote a little shellscript to use rdiff-backup via cronjob.

Code:

# directory for logfile
state='/var/log/rdiff-backup.log'
log='/var/log/rdiff-last.log'

# drive info for backup device (I expect a mounted external device!)
disk='/dev/sdc1'
mountpoint='/media/backup'

# directories to backup (here are the recommended dirs)
# if you want to exclude files, just add them like '- /home/username/music'
# IMPORTANT: first entry hast to be an inlclude and NEVER forget to exclude '/'
#                     or you'll end up with a lot of files ;)
source0='/home'
source1='/etc'
source2='/var'
