I think I'm having a similar situation (see my last email).  What does it
say about BackupPC or the hosts that fulls are working but not incrementals?

Thanks,

Subject: [BackupPC-users] missing incrementals


Hi.
I made recently a debian server with backuppc being a noob in linux, but 
with patience i did it.

So in one host I have this situation. my boss want full backupc to last 
no less than 2 months and preferably would I have the possibility to 
burn to dvd an old backup, to put in the archive/vault...
anyway, i put $Conf{FullKeepCnt} = 6; and {FullPeriod} = 6.97;

 /var/lib/backuppc/pc/fb_nt/116
117                     incr     no     9/10 13:00     4.7     1.9

 /var/lib/backuppc/pc/fb_nt/118
119                     incr     no     9/12 02:00     5.1     0.4    
 /var/lib/backuppc/pc/fb_nt/119


But now my boss looks at this and ask's me where did the incr from day 7 
and 8 go?
    

What is your $Conf{IncrKeepCnt}?
6, i think I will put 14 cause I do 2 incr per day... but do I have to put 14 to fill the incr per full's, or what?!

  
I didn't know either but i searched for documents modified in that date 
and they appear in the web interface but I don't know what happened... 
that might be something like hardlinks or so..
Do you have a way to explain this?
    

Incrementals are made based on change from the last full so you only
need intermediate ones to find files that were newer than your full but
subsequently changed or deleted.
I think I didn't explain correctly...
there is the 111 incr that was deleted right? the files of that incr were deleted also?
the question is this, if a file is modified after the 110 full, is kept in 111 incr, but 111 incr is no more, so where that file go?!
