Sorry, I should have included that. Yes, that argument is there (it
was already there). The RsyncArgs setting is otherwise unchanged from
the default (in other words, we just uncommented that line).

Cool, thanks for explaining that so clearly.

Ditto. :)

This is the one I was really hoping to get an answer on. Once again,
thanks for the complete explanation.

Yeah, that seems to be the general wisdom, and probably would have
fixed it for me (I did some web searches and found that stuff and tried
it before emailing) if I hadn't already written a fatal flaw into my
per-host config file. See my next reply (to Travis Fraser). :)
Note to BackupPC "powers that be": you may want to consider taking the
substantive content out of the email that this is a reply to
(message-id <[EMAIL PROTECTED]>) and putting it
in the main documentation. Of particular use, I think, would be a
fleshed-out example of a full-blown array exclude with multiple shares
and wildcards to demonstrate all the permutations. Perhaps something
like this (note: I don't know enough about perl to know if you're
allowed to put comments inline like that, so this may or may not be a
valid config fragment):
$Conf{BackupFilesExclude} = {
'/' => [
'/dev/', ## /dev is actually safe to back up if you like, though
'/tmp/',
'mnt/', ## I have multiple directories called 'mnt' throughout the
filesystem, don't want to back up any of them
'/floppy/',
'/cdrom/',
'/proc/',
'/sys/',
'/net/',
'/media/'
],
'/var' => [
## We use leading '/' characters here so the paths are all anchored to
the top of the share
'/log/maillog',
'/lib/mysql/data/',
'/lib/mysql/mysql/',
'/log/mysql/mysql.log',
'/log/mysql/mysql-bin*',
'/spool/exim4/',
'/something' ## This will exclude 'something' regardless of whether
it's a file or directory, since there's no trailing '/'
],
};
