That question doesn't make sense, but I presume you want a global exclusion
list that applies in addition to optional individual share lists. You can get
close to what you want, but you'll break the web configuration editor, or
rather, the web configuration editor will not correctly preserve your changes
if you use it on the host configuration file(s) in question.

You simply create a variable in the host (or even global) config file ...

my @common_excludes = ('*access_log*', '.apdisk', '*/.apdisk','.cache');

(I'm not sure what you are trying to achieve by listing '*/.apdisk' as well
as '.apdisk', though) and then referencing that multiple times:

$Conf {BackupFilesExclude} = {
'/home' => [ @common_excludes ],
'/var'  => [ @common_excludes, '/lib/mysql' ],
'/usr'  => [ @common_excludes ],
'/boot' => [ @common_excludes ],
'/data' => [ @common_excludes ],
};

or

$Conf {BackupFilesExclude} = {
'/var' => [ @common_excludes, '/lib/mysql' ],
'/example' => [ ], # no excludes here
'*'=> [ @common_excludes ],
};

Well, syntactically you are missing closing braces and a semicolon.
Semantically, you are assigning one value and then overwriting it with
another, just like in

$a = 'foo';
$a = 'bar';

For BackupPC, you are first creating an exclude list for a share with the
somewhat awkward name '/home, /var, /usr, /boot, /data' (which is "data"
within "boot, " within "usr, " within "var, " within "home, " within the
root directory), which is doubtlessly a valid path, just not one whose
name you'd like to quote to a shell.

So, no, that won't work for several reasons. Aside from that, it would also
break the web configuration editor.

Considering "trivial", I tend to disagree, at least with vi ;-). Consistently
*changing* the list might be a different matter. But I agree with your point.


As a side note, I believe you can prevent a host configuration file from
being edited (by the user) with the web configuration editor by setting

$Conf{CgiUserConfigEditEnable} = 0;

(inside the host configuration file). This might be advisable if you made
changes incompatible with the web configuration editor to prevent accidental
damage. Note, though, that this will probably not prevent an *admin* user
from clobbering the file with the web configuration editor.

Regards,
Holger

Maybe you find something interesting in the web-server log.

I've seen such an error before, but I don't remember what caused the problem. I 
think CGI returns something else instead of image. If you are lucky it might be 
an error message. Try to save this object as file and inspect its content.

IP addresses in the tag and link don't match (192.168.2.90 != 192.168.15.2). 
Don't you think it's weird?

Sorry Alexander,

my problem is as follows:

In the CGI, instead of graphics, there are two unidentified icons.  The 
permissions of pool.rdd are correct (-rw-r-  1 backuppc backuppc 
11784 ago 31 01:03 pool.rrd).
If I try to open the image in the CGI i get the following error : 
http://192.168.2.90/backuppc/index.cgi?image=4 
 cannot be displayed 
because it contains errors.


thanks and sorry English
Orazio

You didn't mention the problem you have.

Assuming you see image placeholders instead of empty graphs in the CGI:
1. Check current $LogDir and pool.rrd permissions with `ls -l` command. 
pool.rrd should be writable for backuppc user and readable for CGI user 
(commonly the same as backuppc user).
2. Modify the permissions appropriately using chown, chgrp, chmod.

In case you see empty graphs in the CGI after BackupPC installation - there is 
nothing to graph yet. Just wait for 2-3 days.
