Hello Luc,

You"re right. I misunderstood the issue here and thought that Martin need to exclude compresses files from its backup.

I think the bellow now will work as desired:

FileSet {
Name = "Full Set"
Include {
Options {
Compression = gzip
RegexFile = ([^\.g?zip]|[^\.jpe?g])$
}
Options {
Signature = MD5
RegexFile = (\.g?zip|\.jpe?g)$
}
File = /
}
}

Best regards,
Ana

Yes, exclude will cause the matching files to be excluded.

 

What I’m not certain of in the configuration I posted is whether it won’t exclude everything, I never tried working with two separate options sections in the same fileset.

 

It could be that it will (exclude everything), and that you have to use two separate ‘Include’ sections, each with one of the ‘Options’ sections, to get the effect you wanted (or at least I think you wanted).

 

Like this:

 

Fileset {

                Name = “FullSet

                Include {

                               Options {

                                               RegexFile = regex_for_uncompressed_files

                                               Exclude = yes

                                }

File = /

}

Include {

                                Options {

                                               Compression = gzip

                                               RegexFile = regex_for_compressed_files

                                               Exclude = yes

}

File = /

}

}

 

I think this is the way to avoid that “this configuration does not work” comment in the documentation, but I’d have to test it to be certain.

The first include would handle “everything excluding uncompressed files”, i.e. all compressed files, and back them up without compression.

The second would include “everything excluding compressed files”, i.e. all uncompressed files, and back them up with compression.

Hi Luc,

 

doesn't mean the Exclude-option, that the files found with the "RegexFile"-option will be excluded from backup? or how can I understand this exclude option?

Hi Ana,

 

Won’t your solution exclude compressed files, instead of including them without a second round of compression?

I think if it can be done, what the OP asked, the right approach would be closer to his own, just using ‘RegexFile’ instead of ‘RegexDir’.

 

I would have tried something like this (untried, untested, probably wrong):

 

Fileset {

                Name = “FullSet”

                Include {

                               Options {

                                               RegexFile = regex_for_uncompressed_files

                                               Exclude = yes

                               }

                Options {

                                               Compression = gzip

                               RegexFile = regex_for_compressed_files

                               Exclude = yes

}

File = /

}

}

 

A bit of De Morganized Boolean logic should circumvent the problem that all files not matched by any Options directive are included by default.

The first Options will exclude all uncompressed files – meaning include all compressed, and back them up without compression.

The second will exclude all compressed files – meaning include all uncompressed ones, and back them up with compression.

Hello Martin,

 

FileSet {
  Name = "Full Set"
  Include {
     Options {
          compression = gzip
     }
     Options {

           RegexFile = "\.[gG]?[zZ][iI][pP]"

           RegexFile = "\.[jJ][pP][eE]?[gG]"

          exclude = yes          

     }
     File = /
  }
}

 

This should work.

 

Best regards,

Ana

Hello,

 

I'm searching help with a fileset which only compresses files which are not already compressed (like gzip,jpeg,mpeg and so on) in my whole root directory..

my first idea was the following:

 

 

FileSet {
  Name = "Full Set"
  Include {
     Options {
          RegexDir = regex for all files with ending .gzip, .zip, .jpeg, and so on
     }
     Options {
          RegexDir = inverted regex from above, don't know if this works

          compression = gzip
     }
     File = /
  }
}

 

but then I saw the examples at http://www.bacula.org/5.2.x-manuals/en/main/main/Configuring_Director.html so that this doesn't work..

 

does anybody have an idea how to solve this without creating two filesets for one client?

 

thankfull for any help,

 

greets

martin
