Hi everyone,

We are planing to implement AI jobs for one of our projects and we decided to 
make tests before on a running infrastructure (Version: 18.2.6).

The problem is AI jobs are backing up less files than original incr job. To do 
our test we copied a normal job :


*list job=denver-always-incremental
Using Catalog "MyCatalog"
+--------+---------------------------+--------+---------------------+------+-------+----------+---------------+-----------+
| jobid  | name                      | client | starttime           | type | 
level | jobfiles | jobbytes      | jobstatus |
+--------+---------------------------+--------+---------------------+------+-------+----------+---------------+-----------+
| 21,197 | denver-always-incremental | denver | 2019-03-15 15:03:10 | B    | F  
   |  147,998 | 2,079,207,003 | T         |
| 21,217 | denver-always-incremental | denver | 2019-03-16 01:51:21 | B    | D  
   |      341 |    32,224,492 | T         |
| 21,254 | denver-always-incremental | denver | 2019-03-18 01:15:39 | B    | I  
   |       17 |     1,524,336 | T         |
| 21,290 | denver-always-incremental | denver | 2019-03-19 01:15:34 | B    | I  
   |       20 |     4,419,477 | T         |
+--------+---------------------------+--------+---------------------+------+-------+----------+---------------+-----------+
*list job=denver
....

| 21,216 | denver | denver | 2019-03-16 01:50:56 | B    | D     |      341 |    
32,223,670 | T         |
| 21,253 | denver | denver | 2019-03-18 01:14:34 | B    | I     |    1,291 |   
184,462,873 | T         |
| 21,289 | denver | denver | 2019-03-19 01:14:43 | B    | I     |    2,413 |   
132,643,290 | T         |

As you can see, starting from same base (same differential job on 2019-03-16) 
does not provides same results.


* File set is same
* "estimate" provides same results. Only Incr jobs are "buggy"

Here is a copy of our config files :

job
{
  Name = "denver"
  FileSet = "denver"
  Schedule = "WeeklyCycle"
  Client = "denver"
  JobDefs = "DefaultJob"
  Write bootstrap = "/var/lib/bareos/bstraps/denver.bsr"
  Accurate = yes
}

Job
{
  Name = "denver-always-incremental"
  FileSet = "denver"
  Schedule = "WeeklyCycleAlwaysIncremental"
  Client = "denver"
  JobDefs = "DefaultJob"
  Write bootstrap = "/var/lib/bareos/bstraps/denver-always-incremental.bsr"
 
    # Always incremental settings 
    AlwaysIncremental = yes 
    AlwaysIncrementalJobRetention = 7 days 
    Always Incremental Keep Number = 6
    
    Accurate = yes 
 
    Pool = AI-Incremental 
    Full Backup Pool = AI-Consolidated 
}

 
Job { 
    Name = "denver-always-incremental-consolidate" 
    Type = "Consolidate" 
    Accurate = "yes" 
    JobDefs = "DefaultJob" 
}
 

FileSet
{
  Name = "denver"
  Ignore FileSet Changes = yes
  Include {
    Options {
      signature = MD5
      compression = gzip
      noatime = yes
    }
    File = /
    File = /boot
    File = /home
    File = /var/log
  }
  Exclude {
    File = /proc
    File = /sys
    File = /tmp
    File = /.journal
    File = /.fsck
  }
}




JobDefs {
  Name = "DefaultJob"
  Type = Backup
  Level = Full 
  Client = baloo
  FileSet = "Full Set"
  Schedule = "NONE"
  Storage = File 
  Messages = Standard
  Pool = Month
  Priority = 10 
  Accurate = yes
}


Do is it a bad configuration or it could be a bug ?

Thank you !
