Hi, I'd like to setup an automatic backup system cause I don't want to
tag my mails twice and I don't want to loose the information about
archived mails etc.
What do you think about something like this?
Is it enough to keep 4 dumps?
What about moving this code into sup shutdown?
I think everyone wants to have this feature?
run_sup(){
# untested draft
local dump_dir="/var"
sup
sup-dump | bzip2 > "$dump_dir/sup-dumps-`date`"
ls -1t "$dump_dir"/sup-dumps-* | { read; read; read; read; cat } | xargs rm
}

"{ read; read; read; read; cat }" could probably better be done as
"tail +5"; makes it easier to adjust to people's choice of backup
count, too. ;-)

Or:
DAYS=5
find $dump_dir -mtime +${DAYS} -name "*sup-dumps-*" -print0 | xargs -0 --no-run-if-empty rm
(adjust xargs options to suit your environment...I don't think
--no-run-if-empty is all that portable.)

"tail -n+5", which is POSIX compatible
