If a full backup of all your data fits on one tape and you aren't time
constrained, I would recommend doing a full on everything every night.
Set dumpcycle to 0 and runspercycle to 1.  It will make restores easier
(you'll only need one tape) and you'll have multple tapes to recover from
if one should fail.  When your data gets bigger and no longer fits on a
tape, you can change dumpcycle and runspercycle to 2 and you'll still
have at least 3 full backups of everything on tape, or change runtapes to
2 and only have 3 days of historical backups.
