Here's mine, which illustrates that:  10, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23

You can put it in whatever order you want.  The way it is above, it's clear that there's a reason 10 is in the front:  it's not random, and it's not in order.  Smart people might wonder why, and then read the help to find out why!  :)

With BackupPC, you have to give up a little control to get it to work best.  Some people are like you (the original poster, that is) and want it to run at a specific time:  "Every Monday and Thursday".  It is *not* designed to work that way.  (If you wanted incrementals in that mix, it would be impossible to do without scripting things *outside* of BackupPC, such as a cron job.)  Some people just must hold onto the bad old days of tape backup when *everything* was launched by a cron job...  forgetting what happens when you *miss* that single moment in time.

The wakeup schedule is another example of people trying to exercise total control over BackupPC.  It's better to just let it do its job than try to restrict it.

Admittedly, there are annoyances with this.  For example, a regular request is the ability to run a full backup on the last day of the month.  You can't do that within BackupPC alone.  I can certainly understand (e.g.) regulatory requirements for things like that.  But it's not how BackupPC is designed to work.
