After re-reading the documentation for {IncrLevels} again the
configuration settings are starting to make sense. The only question
I have left is, does creating a new "full" backup *have* to do the
entire full backup again? Can't it just perform an increment and
merge it to create a full? The reason I ask is I'm planning on moving
this server off-site so it'll go over a WAN. Sending 250G over a 1M
connection every week or two doesn't sound fun! Is this what
$Conf{IncrFill} is supposed to handle?
What I want is to basically perform a backup every day and keep 30
days of backups without doing another 'full' backup. I don't really
care how many 'full' backups I have as long as I can restore from 29
days ago. Would these settings do the trick for that?
$Conf{FullPeriod} = 30;
$Conf{IncrPeriod} = 1;
$Conf{IncrKeepCnt} = 30;
$Conf{IncrLevels} = [1, 2, 3, 4, 5, 6 ...... 30];
$Conf{IncrFill} = 1;
This may start to get off topic, so I can start a new thread if needed.
Thanks for your help!
Regards,
Mike
