On Solaris this would be ufsdump, and other folk may have different

Right then, now:
dmp_cmd='"${dump}" -${level}${dump_flags} "${device}" | gzip -9'
[[ ! -z ${encryption} ]] && dmp_cmd="${dmp_cmd}"' | ${encryption} -pass
"file:${conf}.passwd"'

So that is working, ta muchly!
I'll have to audit the other scripts in the suite:
dumpster
dumpster_backup
dumpster_offsite
It is shaping up quite well, here is a partial list at my ISP, showing
various periods & towers of hanoi:
$ cd ~/dumpster/cedar
$ ls -1 _home*
_home_0.dump.gz
_home_1_Quater-1.dump.gz

_home_2_March.dump.gz
_home_2_May.dump.gz
_home_3_Week-00.dump.gz

_home_8_Sunday.dump.gz
_home_9_Saturday.dump.gz

Next TODO is to get it running as operator, like amanda. Plenty of
sudo ahead, me thinks...
OpenBSD is the best for this! Everything one could need is in base,
and... it all works! Kudos to the team.
