Define (at least) 3 management classes, probably all being other than
default.
I always name mine to reflect their settings like B7.3_R35.95_A35
where B7.3 reflect Versions data exists & deleted
where R35.95 reflect Retain extra & only days
where A### is the number of days an "A"rchive is retained...
Now, set one, say blah_A5, with an archive copy group with 5 day retention
set one, say blah_30, with an archive copy group with 30 day retention
set one, say blah_365, with an archive copy group with 365 day retention
(personally I use 35 for a month and 370 for a year)
Then Monday through Friday  other than the first of the month you will need
to set (in your TDP configuration file) to use the blah_A5 management class
every Saturday, other than the first of the month, you will need to set TDP
to use the  blah_A30 management class
and every 1st of the month, set TDP to use the blah_A365 management class...
