You can start 2 backups with 2 different prefixes. That way you can 
enforce 2 different prune policies.

borg create ::var_{now} /var /etc
borg create ::data_{now} /data

borg prune --keep-daily=7 --prefix var_
borg prune --keep-hourly=12 --keep-daily=7 --keep-weekly=4 --prefix data_


Of course you can use 2 different repositories as well. Its' up to you, 
whatever fits you best. Keep in mind though that you loose the advantage 
of deduplication across all data, which will probably make 2 separated 
repositories bigger than 1 combined repository.
