Backup Central

Hi all,

Thanks to William, I have figured out how to put a config file on a per
pc basis.

This is what I've done.

__TOPDIR__ == /backuppc

so, I've got the main config file as /backuppc/conf/config.pl and hosts
in /backuppc/conf/hosts (this file currently has only 1 host specified
as dhcp -> marks-desktop)

/backuppc/pc/marks-desktop/config.pl contains the following::
do "/backuppc/conf/config.pl
$Conf{SmbShareName} = 'TestBackup';
#completion of marks-desktop config file

When I connect to the cgi interface, it says that it can successfully
ping marks-desktop (from marks-desktop home page). But when I click for
a perform Full Backup Now, it says in the error log that It was unable
to backup C$ share on marks-desktop! the contents of Xfer-log for
marks-desktop::
Running: /usr/bin/smbclient \\\\marks-desktop\\C\$ -I 172.16.102.169 -U
-E -N -d 1 -c tarmode\ full -Tc -
Xfer PIDs are now 4640,4639
Domain=[TECHNOLOGY] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]
tree connect failed: NT_STATUS_ACCESS_DENIED
tarExtract: Unexpected end of tar archive (tot = 512, num = , posn = )
tarExtract: Done: 1 errors, 0 filesExist, 0 sizeExist, 0 sizeExistComp, 0 filesTotal, 0 sizeTotal

I see 10 problems here:
(0) somehow the share name has not been over-ridden (its specified in
config.pl for marks-desktop)
(1) whats the tree connect failed thingy? I can connect to the machine
and browse the shares there. I actually have Full permissions on the
TestBackup folder on marks-desktop!

Should I remove the smbsharename config attribute (C$) from the main
config.pl file? The default config.pl file defaults $Conf{XferMethod} to
smb.

Regards,
Imran

Hello people,

Ok, I've figured out the solution for problem (0). Its was my fault:
didn't finish the perl statement with ; :p

Problem (1) still exists. Every time I try to do a backup, it craps with
the same error.

Imran

As you noted in your following email, you were missing a ';'.
But, more importantly, there is no need to include the main
config.pl. So all you need is a one-liner:

$Conf{SmbShareName} = 'TestBackup';

When I connect to the cgi interface, it says that it can successfully
ping marks-desktop (from marks-desktop home page). But when I click for
a perform Full Backup Now, it says in the error log that It was unable

See above.

(1) whats the tree connect failed thingy? I can connect to the machine
and browse the shares there. I actually have Full permissions on the
TestBackup folder on marks-desktop!

And you've discovered you don't have any permission
(NT_STATUS_ACCESS_DENIED) for the share C$.

Your problem is not related to BackupPC. You are simply seeing that
smbclient cannot connect to the share.

- look at the smbclient command it is running.

- try running the smbclient command manually as the backuppc user
(pipe output to tar -tvf -).

- figure out what command options and user/password acutally work.

- change config settings to match the command and user/password that
works in your setup.

Thanks for the replies Craig. Somehow t doesn't work without a required
username/password. Adding -guest works fine for me now.

So a patch follows.. hopefully it is useful to somebody.

=====================================================

Also the smbpassword is not being used as somebody else mentioned.
