If you have many logfiles, mailboxes, or database files you'll burn up a
lot of space keeping every incremental. Do you need to be able to
restore from any day's backup or would one a week be enough after you go
back a month or so? Regardless, I'd try to stick with weekly fulls and
daily incrementals (the defaults) and set $Conf{FullKeepCntMin} to a
very large number so fulls won't ever be deleted and
$Conf{IncrKeepCntMin} to the number of days back that you'll need daily
access (or also very large if you don't want any incrementals to be
deleted).
