=46rom my own systems.

#    Full backup every week
$Conf{FullPeriod} =3D 6.67;

#    Keep 4 backups @ 1 week
#              4 @ 2 week
#              3 @ 4 week
#              1 @ 8 week
#               2 @ 16 week
#    Over 1 years backups
$Conf{FullKeepCnt} =3D [4, 4, 3, 1, 2];


=46ull backup every week. Keep the last 4 weekly backups. Keep another 4 ba=
ckups=20
before this at 2 weekly intervals. Keep another 3 backups before that again=
=20
at 4 weekly intervals and so on. The period between the retained backups=20
doubles each time.

Hope this explains things,
