[Dirvish] Backup strategy for a home computer

[Johannes Kastl]

Hi everyone,

I tested dirvish for a while, and everything seem to work fine. So Im
thinking about how to use it for the real backup.

My biggest "problem" is that my computer is not running 24/7, so the
different expire-Rules seem to be a bit more complicated.

What I know is that

- it normally runs once a day, so I will run dirvish at boot time, and
I will get one backup per day
- I would like to keep Backups made on sundays/mondays longer than others
- I would like to keep one Backup of each month for 1 year

So I thought about it, and tried to test the sunday/monday thing:

> expire-default: +1 weeks
> expire-rule:
> #MIN    HR      DOM     MON             DOW     STRFTIME_FMT
> *       *       *       *               1       +2 weeks
> *       *       *       *               2       +2 weeks

I tried dirvish --vault NAME --no-run, and it always said
"Expire: +1 weeks == ..."

So I tried this to see if I got the DOWs wrong:

> expire-default: +1 days
> expire-rule:
> #MIN    HR      DOM     MON             DOW     STRFTIME_FMT
> *       *       *       *               1       +2 days
> *       *       *       *               2       +3 days
> *       *       *       *               3       +4 days
> *       *       *       *               4       +5 days
> *       *       *       *               5       +6 days
> *       *       *       *               6       +7 days
> *       *       *       *               7       +8 days

But it still says: "Expire: +1 days == 2006-08-29 12:25:09".

What is wrong there?

And, how could I keep one backup per month for 1 year, if it is not
sure that the machine is always running on the first day of the month?

Thanks for your help,
OJ
