Well, it looks like I made a small typo here (rather my International keyboard
bit me). It should be:
regex = "^.?*$"
However, life is never so simple; even that is wrong. Why? because it
excludes everything even /home/df/test. The correct solution is to use:
RegexFile = "^.?*$"
which excludes all files but not the directories.
So the complete correct FileSet *should* be:
FileSet {
Name = "Test Set"
Include {
Options {
WildFile = *.tar.gz
signature = MD5
compression = GZIP
}
Options {
exclude = yes
RegexFile = "^.?*$"
}
File = /home/df/test
}
}
With the above, Bacula will backup all your *.tar.gz files as well as all the
directories (no files) including and under /home/df/test. It is probably
better to let the directories to be backed up so that if a file is restored,
all the directories leading down to it are also restored with the proper
owners/permissions.
Note, Regex/RegexFile/RegexDir do not work on Win32 systems since it is not in
the Microsoft libraries, and I haven't take the time to dig out the source
code and include it in Bacula.
