Hi,

I am new to backuppc so please apologize if this has been asked before.

I am testing backuppc for a few weeks now. Works very robust and fast. 
But I wonder about the number of files and directories backuppc creates 
in an incremental dump.

I am backing up server2 with a filesystem containing about 3 million 
files spread over about 300,000 directories. backuppc's summary for 
server2 tells me
Level 0:
   3084565 files (470 GB), 1159994 files (60GB), 2150650 files (410GB)
Level 1:
   11024 files (2.8 GB), 8482 files (101 MB), 60139 files (2.7 GB)

Counting the number of files on the backup-device leads to
/path/to/backup/pc/server2/0: 3634406 files (including directories)
/path/to/backup/pc/server2/1: 429770 files (including directories)

Investigating the differences regarding the level 1 dump, I found out 
that the whole directory structure of the filesystem is created for the 
incremental dumps, independent if the dir contain files to backup or not.

I think this may lead to problems regarding the number of files on the 
backup-device. My whole test setup running for 2 month lead to 140 
million files/hardlinks/directories. Filesystem checks or removing of 
large parts of the backup took substantial amounts of time.

Option IncrFill is not set neither global nor for the client.

Is this layout really necessary? Can I avoid creating the whole dir 
structure?

Christoph
