Some additional input:

- Disabling accurate mode results in a "resonable" list of files from the estimate command.

- Changing accurate options does not change the files displayed with estimate. Even specifing a size-only check (accurate = s) results in the estimate list containing all files.

- This issue seems present will all of my Ubuntu bacula clients.

Thanks

Hi list,

I'm using Bacula 7.0.5 on Ubuntu 16.04. I configured daily incremental backups in accurate mode, with accurate options "mcs". Since upgrading to Ubuntu 16.04 and Bacula 7.0.5 I experience really huge incremental backups.

Estimate gives me 1,943,557 files that will be backed up on next incremental backup. One example from estimate output:

-rw-r--r--   1 root     root            1371 2015-12-13 12:06:43  /etc/rsyslog.conf

While stat /etc/rsyslog.conf results in:

  File: '/etc/rsyslog.conf'

  Size: 1371           Blocks: 8          IO Blocks: 4096   regular file

Device: 801h/2049d       Inode: 13909238    Links: 1

Access: (0644/-rw-r--r--)  Uid: (    0/    root)   Gid: (    0/    root)

I interpret option "accurate = mcs" as: "A file will be backed up, if mtime, ctime or size has changed since the last backup." As one can see from the above stat output none of the three has changed. I therefore do not understand why this file (and several thousand other files) get backed up every night.

My FileSet config looks like this:

FileSet {

        Name = "FileSet_Alles_Linux"

        Ignore FileSet Changes = yes

        Include {

                Options {

                        signature = MD5

                        accurate = mcs

                        _onefs_ = no

                        compression = gzip

                        noatime = yes

                        xattrsupport = yes

                }

 

                File = /

        }

 

        Exclude {

                File = /sys

                File = /var/lib/bacula

                File = /proc

                File = /dev

                File = /tmp

                File = /.journal

                File = /.fsck

                File = /srv/bacula

                File = /var/spool/squid

        }

}

The job is running as an incremental job and is not upgraded during runtime.

Any help is highly appreciated. If you need any further information, let me know!

Thanks
