How to schedule a task to run every weekday except on the 1st day of the month

Question

How to schedule a task to run every weekday except on the 1st day of the month?

To avoid the XY problem: I'm building a backup system that makes backups on the 1st of every month and daily backups every weekday. I have three tasks running three programs:

1. Monthly backup - 1st of every month
2. Daily backup - mon-fri
3. Clear old backups - every day

I keep X monthly backups and Y daily backups. If the 1st happens on a weekday, I get two backups very close to each other and I want to avoid the hard drive cost

Win 7, Win server 2008 and Win server 2012 platforms.

Answer 1

Get your scheduled task to run a batch script. In there, you can put

SET DATE=%DATE%
SET DAY=%DATE:0,2%

This will set the environment variable DAY to the first two characters of the date, which (on my system) comes as dd/mm/yyyy. (Obviously check this first using echo %DATE%.)

Then you can exit the script if DAY is equal to 01, and run your backup program if it's not.
