Hi Del,
thanks, that's what I'd expected. What I'll do is something along the lines of:
tdpexcc backup * incremental /excludedb="these_go_full_today" /preferdagpassive
(and more stuff)
tdpexcc backup "these_go_full_today" full /preferdagpassive (and more stuff)
and have the script determine what "these_go_full_today" will be for each day
of the week, based on a simple array. It'll probably be powershell because I
like it and it does provide the functionality I'll need like actual access to a
simple function to indicate the day of the week and arrays and stuff. I'll
lookup the URL that you provided.
O, and yes, what Erwann said.
