after only running the commands for the target web2 from
import-rsnapshot-cmd.sh

my bupdir is 2.1G

# rsnapshot du mail2

234M    /var/backup/monthly.2/mail2
7,2G    insgesamt

after bupping mail2

bupdir 4.6G

web2 and mail2 both run the same version of the same os, so there's some
potential for deduplication. mail2 is, as the name says a mailserver so
a lot of textfiles -> good, too.

rsnapshot: 12.6G
bup: 4.6G

i think we have a winner here.
