Backup Central

Hi,
I want to backup a linux pc and only the home directory and its
subdirectories /home/username/
but i don't want to backup hidden directorys like .kde or .ssh or stuff like
that and also not *.mp3 which can be everywhere files.

I will use rsync for it
is this a correct setting?
$Conf{RsyncShareName} = '/home/user';
$Conf{BackupFilesExclude} = ['/.*','*.mp3'];

or will this fail?

thanks

ciccio

A quick demonstration with 'ls' will show that the '/.*' construct is
something to be avoided.

$ ls /.*
/.:
bin boot cdrom dev etc floppy home initrd lib lost+found mnt proc
root sbin tftpboot tmp usr var

/..:
bin boot cdrom dev etc floppy home initrd lib lost+found mnt proc
root sbin tftpboot tmp usr var


in your case, even if you set the working root to /home/username; the '/.*'
regex would (should?) cause the application to go up one directory level
(because .* includes '..') and exclude the directory which you are in.

It usually only takes one thoughtless 'rm -rf .*' before you learn a very
painful lesson. (and why backups are a good thing!).

If you want to catch all the dotfiles in your regex; the ways to do it are:
- .??* <--which will miss anything like '.a', unfortunately
- /path/to/dir/.* <--which means you need to specify a path above the
directory... not always possible.
- .[A-Z,a-z]* <--should work most of the time, provided there are no funky
characters starting the name

there's probably something better, which I can't think of right now. Anyone
else?

none of the above work, only the last one works with files. all the .blabla
directories are still backed up.

thanks Mr Wilhelm you brought me up to this idea which works
for directories ie */.* if you put this in your regexpr then no hidden
directories will be backuped whereever they are
for files ie .*
works like a charm

greets
klaas

ah, there you go.
I know I've used that in the past, with other backup systems; just didn't
think of it right away this morning.

Yes, but rsync specifically removes the "." and ".." directories
when it traverses the directory tree, so they never match. Here's
the code from flist.c:

if (dname[0] == '.' && (dname[1] == '\0'
|| (dname[1] == '.' && dname[2] == '\0')))
continue;

Therefore, I believe (without testing), that "/.*" should exclude
all top-level directories and files that start with "."
(eg: /home/user/.*, but not /home/user/..).

And something like ".*/" should exclude just directories (not files)
at all levels, including the top level.
