Hello!

Short summary:   it seems that whenever the file is dropped from phase 0 
of a rsyncd backup and retried in phase 1 the file does *not* show up in 
the GUI.  However, the file *is* actually stored in the proper 
pc/<server/<path>/ directory.


Long description:

I had to restore a file today.  The file is a backup of an Exchange 2003 
datastore that is created by NTBACKUP running on the Exchange server. 
This file, therefore, changes every day, and is ~20GB big.  The server 
is then backed up using rsyncd to the BackupPC server.

It seems that there is approximately a 50% chance that I'm going to see 
something like this in the log file for the BackupPC backup of this machine:

BAK/ExchangeDataStore/ExchangeData.bkf: md4 doesn't match: will retry in 
phase 1; file removed

 From my understanding, this is a normal byproduct of the way rsync 
transfers files:  due to hashing issues, the file will be removed from 
phase 0, but will be retried in the more exhaustive phase 1.  This seems 
to be demonstrated in the log for such a backup.  At the very end of the 
log I see this:

create   700 4294967295/401 21050720256 
BAK/ExchangeDataStore/ExchangeData.bkf

Which seems to me to mean that the file was indeed backed up properly. 
So far, so good.

However, here's what the GUI looks like for that file in the history of 
the BAK/ExchangeDataStore directory:

History of D/BAK/ExchangeDataStore

Backup number   27      47      59      73      87      101     107     108     
109     110     111     112     113
Backup time     9/19 20:00      10/26 02:00     11/20 15:09     12/4 20:00      
12/18 20:00 
1/1 20:00       1/7 20:00       1/8 20:00       1/9 20:00       1/10 20:00      
1/11 20:00      1/12 
20:00   1/13 20:00
ExchangeData.bkf        v0      v1      v2      v3      v4      v5              
v6              v7      


The formatting is near useless, but notice this:  there are 14 backups 
represented on that screen (between 27 and 113), but only *7* versions 
of the file in the history.  From checking the logs, it seems that 
whenever the file is retried in phase 1 the file does *not* show up in 
the GUI.  However, if I go to the actual backuppc pc/<server>/<path> 
directory, the file *is* actually in the proper directory.

Is this a bug in the BackupPC GUI?  Or am I missing something?
