Re: [BackupPC-users] BackupFilesExcludes for Linux
I think I spotted a mistake in my own speculative config. See below.

Greetings. Me again.
I upgraded my backup server and configured two hard drives into a single
logical volume with LVM for my TopDir, and successfully configured
BackupPC to backup a share on one of my host machines. Rejoicing was
heard throughout the LAN.
Now, I am faced with the necessity of backing up my /etc and some of my
user's home directory on that machine.
I want to exclude several directories under my user's home directory,
but the information I've seen is all about configuring BackupPC for a
Windows host. I am assuming I need to change this:
$Conf{BackupFilesOnly} = {
'*' = [
'images',
'Photos'
]
};
$Conf{RsyncShareName} = [
'/mnt/share'
];
$Conf{ClientNameAlias} = '192.168.1.106';
To this:
$Conf{BackupFilesOnly} = {
'/mnt/share' = [
'images',
'Photos'
]
'/' = [
'etc'
]
'/home' = [
'madams'
]
};
$Conf{BackupFilesExclude} = {
'/home/madams' = ['/torrent', '/Download'],
};
$Conf{RsyncShareName} = [
'/mnt/share', '/home/madams', '/etc'
];
$Conf{ClientNameAlias} = '192.168.1.106';
Is this right, or do I misunderstand this configuration?
Thanks.
I believe the $Conf{RsyncShareName} statement should involve '/' rather
than '/etc'. The directory I want to backup is /etc which is a
subdirectory of /. I also believe the /home/madams directory should be
/home. Am I right?

And do you think (fop that I am) that I could be the Scarlet Pumpernickel?

$Conf{RsyncShareName} should contain the directories which should backuped.
If it contain '/' than all subdirectories, including /etc will be backuped,
if it is not on another filesystem and you use --one-file-system.
If it contain '/etc' than only /etc and all subdirectories of /etc will be
backuped.

$Conf{BackupFilesOnly} = {

[edited to match your correction]

$Conf{ClientNameAlias} = '192.168.1.106';
As Matthias probably meant to point out, you can achieve the same with
$Conf {RsyncShareName} = [ '/etc', '/home/maddams', '/mnt/share/images',
'/mnt/share/Photos' ];
$Conf {BackupFilesExclude} = { '/home/maddams' = [ '/torrent',
'/Download'] };
or even
$Conf {RsyncShareName} = [ '/' ];
$Conf {BackupFilesOnly} = {
'/' = [ '/etc', '/home/maddams', '/mnt/share/images',
'/mnt/share/Photos' ],
};
$Conf {BackupFilesExclude} = {
'/' = [ '/home/maddams/torrent', '/home/maddams/Download' ],
};
This is, of course, just as speculative as your config, but I believe it
*should* work that way :-).
The important part is that the hash keys in BackupFilesOnly and
BackupFilesExclude need to match your {RsyncShareName}s exactly, else they
will simply be ignored (there is no magic that determines that '/home/maddams'
lies within the '/home' share). Aside from that, *with rsync and tar* (not
rsyncd and smb) you are rather free to split your paths into share names and
BackupFilesOnly entries any way you like. Less shares probably means less
overhead and a backup definition that is easier to understand. If you use
'--one-file-system', you will need extra shares for anything on different file
systems (probably '/home' and '/mnt/share' in your case).
Regards,
Holger

systems (probably '/home' and '/mnt/share' in your case).
Also (I believe that) using multiple share names on the same
filesystem will not preserve hard links that are split across the
share names. So, if you are backing up your linux partitions and want
to preserve hard links then you should probably keep all the key root
partitions on the same share (please correct me if I am wrong but I
don't see how rsync would otherwise know about the hard links since
each share is done independently).
