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;

Backup#   Type   Filled   Start Date   Duration/mins 
  Age/days   Server Backup Path
76 full yes 8/21 12:00 85.0 22.0
 /var/lib/backuppc/pc/fb_nt/76
95   full yes 8/30 18:18 58.4 12.7 
/var/lib/backuppc/pc/fb_nt/95
110 full yes 9/6 19:00 61.2 5.7
 /var/lib/backuppc/pc/fb_nt/110
114 incr no 9/9 02:01 4.3 3.4
 /var/lib/backuppc/pc/fb_nt/114
115 incr no 9/9 13:00 4.7 2.9
 /var/lib/backuppc/pc/fb_nt/115
116 incr no 9/10 02:00 4.2 2.4
 /var/lib/backuppc/pc/fb_nt/116
117 incr no 9/10 13:00 4.7 1.9
 /var/lib/backuppc/pc/fb_nt/117
118 incr no 9/11 13:00 5.2 0.9
 /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?!

Put in as many as you want to keep.  14 should keep your 2 a
day between fulls but you could have more if you want longer
to find files that were deleted.

  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

Files are all linked into the pool and to any runs that contain
them.  If changed file is included in run 111 and is still there
in run 112 it becomes another link which stays even when 111
is removed.  The pool copy is deleted only after all the links
to it have been removed.
