+below for more details concerning Options resources.
There can be any number of {\bf Include} resources within the FileSet, each
having its own list of directories or files to be backed up and the backup
Multiple Options resources may be specified one after another. As the
files are found in the specified directories, the Options will applied to
the filenames to determine if and how the file should be backed up. The

-FileSet until the first one that matches.
+wildcard and regular expression pattern matching parts of the
+Options resources are checked in the order they are specified in the
+FileSet until the first one that matches. Once one matches, the
+compression and other flags within the Options specification will
+apply to the pattern matched.
A key point is that in the absence of an Option or no other Option is
matched, every file is accepted for backing up. This means that if
resources that may be present. This means that any wild cards must appear
before an Options resource without wild cards.
-If for some reason, Bacula applies all the Options resources to a file
-under consideration for backup, but there are no matches (generally because
-of wild cards that don't match), Bacula as a default will then backup the
-file. This is quite logical if you consider the case of no Options, where
-you want everything to be backed up, and it is important to keep in
-mind when excluding as mentioned above.

It is a good idea to put all your wild-card and regex expressions inside
double quotes to prevent conf file scanning problems.

\item [compression=GZIP]
-\index[fd]{compression }
- All files saved will be software compressed using the GNU ZIP compression
- format. The compression is done on a file by file basis by the File daemon.
- If there is a problem reading the tape in a single record of a file, it will
- at most affect that file and none of the other files on the tape. Normally
- this option is {\bf not} needed if you have a modern tape drive as the drive
- will do its own compression. In fact, if you specify software compression at
- the same time you have hardware compression turned on, your files may
- actually take more space on the volume.
-
- Software compression is very important if you are writing your Volumes to a
- file, and it can also be helpful if you have a fast computer but a slow
- network, otherwise it is generally better to rely your tape drive's hardware
- compression. As noted above, it is not generally a good idea to do both software
- and hardware compression.
-
- Specifying {\bf GZIP} uses the default compression level six (i.e. {\bf GZIP}
- is identical to {\bf GZIP6}). If you want a different compression level (1
- through 9), you can specify it by appending the level number with no
- intervening spaces to {\bf GZIP}. Thus {\bf compression=GZIP1} would give
- minimum compression but the fastest algorithm, and {\bf compression=GZIP9}
- would give the highest level of compression, but requires more computation.
- According to the GZIP documentation, compression levels greater than 6
- generally give very little extra compression and are rather CPU intensive.

+ not descend into the directory mentioned in the first part of the message.
+ However, it is possible that the separate filesystem will be backed up

This option allows you to select files and directories by the
filesystem type. The permitted filesystem-type names are:

This option allows you to turn on support for Mac OSX HFS plus

There are a number of special cases when specifying directories and files in a
{\bf file-list}. They are:
you must ensure that there is a reader program or Bacula will block, and
after one minute, Bacula will time out the write to the fifo and move on
to the next file.

To accomplish what we want, we must explicitly exclude all other files.

The problem is that the above will include everything in /home. To get
things to work correctly, you need to start with the idea of exclusion
instead of inclusion. So, you could simply exclude all directories

Thanks to Thiago Lima for summarizing the above items for us. If you are
