Hello all,

I have red many times the manual and of course I tried many settings, 
still without luck. I have 30 hosts which have about 1400Megabytes of 
data in summary. As I am using a 2TB harddisk for my backuppc pool, I 
would like (am able) to have just one full backup for all of them. If 
it's possible to have 2 FullBackups due to deduplication, that would be 
nice. But one full Backup is enough, because I dont have more capacity. 
So I would like to have:

- full backup, once a week
- incremental backups, every day until next full backup is done

I have configured:

$Conf{FullPeriod} = '6.97';
$Conf{IncrPeriod} = '0.97';
$Conf{FullKeepCnt} = [1];
$Conf{FullKeepCntMin} = '1';
$Conf{FullAgeMax} = '6';
$Conf{IncrKeepCnt} = '6';
$Conf{IncrKeepCntMin} = '3';
$Conf{IncrAgeMax} = '14';

But I am facing the problem, that I get up to 3-4 FullBackups for each 
host and then the other host backups fail. I cannot explain why this 
happens. I have red, that if an incremental backup is needed for the 
last FullBackup or something like that, but to be hondest I didnt 
understand that :( I also tried $Conf{IncrKeepCnt} = '6'; then I stopped 
BackupPC, manually removed the backups within my pool harddisk, then I 
did a manually nightly_job cleanup with 
"/usr/share/backuppc/bin/BackupPC_nightly 0 255" and restarted BackupPC.

What am I doing wrong? I would really appreciate any assistance for my 
desired backup scheme. What are the correct values for my purpose? Thank 
you.
