[Bacula-devel] Accurate Incremental backup problem


Hi,

I looks like Accurate Incremental backups work not like expected.

I am using current bacula trunk, last update 2008-09-16.
No config changes since last update.

Below is a Job list where i tried to track down the problem.
On Monday Sep 22 i did a system update (apt-get), so 20794 Files are ok for Job 3637.
But i did not make major changes on Sep 23, so 21725 Files for Job 3669 are not expected!


JobId JobName Status Level Client Pool StartTime EndTime Duration Files Bytes
3574 Backup-leodolter OK F leodolter-fd DiskBackup 08-Sep-21 02:05 08-Sep-21 02:26 00:21:45 178,917   4.5 GB
3605 Backup-leodolter OK I leodolter-fd DiskBackup 08-Sep-22 02:05 08-Sep-22 02:06 00:01:27     202  13.3 MB
3637 Backup-leodolter OK I leodolter-fd DiskBackup 08-Sep-23 02:05 08-Sep-23 02:07 00:02:34  20,794 187.6 MB
3669 Backup-leodolter OK I leodolter-fd DiskBackup 08-Sep-24 02:05 08-Sep-24 02:07 00:02:42  21,725 192.6 MB 	


Now i looked at some special file /usr/bin/wget (see mysql select below)
As far as i can see only st_atime (11'th field in LStat) changed from 23 Sep (JobId 3637) to 24 Sep (JobId 3669).

Until now i thought st_atime is not used for Accurate backups.

For me i looks like Accurate Incremental backups are always made against last Full
while ignoring previous Accurate Incremental jobs (maybe i am completely wrong)


mysql> select File.JobId, Filename.Name,Path.Path,File.LStat,File.MD5 from File
  join Filename using (FilenameId)
  join Path using (PathId)
 where File.JobId in (3574,3605,3637,3669) and Filename.Name = 'wget';

+-------+------+-----------+------------------------------------------------------------+-----------------------------+
| JobId | Name | Path      | LStat                                                      | MD5                         |
