I thought about this some time now. Conclusion: The current
FileSet{} Syntax is good, but IMO with some changes/improvements
it would be much more logical and easier to understand.
So I did a bit of a "Mockup" what I think how the FileSet would be
better structured maintaining the same flexibility:
Some definitions (many apply to the current syntax):
* There are two possible sections in "FileSet": "Include" and "Exclude"
There can be one or more Include and zero or one Exclude
statements.
* NEW: FileWild and FileRegex, not only File can be used to select
files in Include and Exclude
* All files matching one of the File* statements will be included into or
excluded from the backup accordingly.
* Any File/FileRegex/FileWild statements can begin with a "!" to
negate it.
* What will be backed up or not can never be controled from within
an "Options" section.
* Options sections will always only set/change parameters of
files to selected for that particular include statement.
# Example fileset with comments:
-------------------------------------------------------
FileSet {
Name = "MyFileSet"
Ignore FileSet Changes = <yes|no> # no change
Enable VSS = <yes|no> # no change
Include { # include /dev/sdf raw with sparse option
Options { # this option matches all File* statements
Sparse = YES # within this Include statement
}
File = "/dev/sdf"
}
# include some dirs, SHA1 for every file,
# compress all files not matching ".*\.(gz|bz2|tgz|tbz2)"
Include {
Options { # this option matches all File* statements
Signature = SHA1 # within this Include statement
}
# compress all files in this include section
# _not_ matching ".*\.(gz|bz2|tgz|tbz2)"
Options {
WildRegex = !".*\.(gz|bz2|tgz|tbz2)"
Compression = GZIP
}
File = "/" # begin at root, stay in FS
File = "/usr" # additional FS mounted on /usr
FileWild = "/lib*" # include /lib, /lib32, /lib64, ...
FileWild = "/usr/lib*" # include /usr/lib, /usr/lib64, ...
FileRegex = "/home/[a-f]*" # include all home dirs beginning
# with one of a,b,c,d,e,f
}
# exclude some of the previous selected files that we do not want
# to backup:
# everything in /tmp and every cache dir in user home dirs
# this applies to any files that matched previously because this
# section is at the end and thus processesd when!
Exclude {
File = /tmp
FileRegex = "/home/*/[Cc]ache"
}
}

Comments please!
