Subject: [BackupPC-users] Cannot Backup SMB Share


The standard configuration does not backup an SMB share. The error message is: 

Contents of file /var/lib/BackupPC//pc/pavilion/XferLOG.bad.z, modified 
2011-10-29 19:30:09 

Running: /usr/bin/smbclient \\\\pavilion\\Users -U amachina -E -N -d 1 
-c tarmode\ full -TcrX - full backup started for share Users 
Xfer PIDs are now 25227,25226 
tar_re_search set 
Anonymous login successful 
Domain=[WORKGROUP] OS=[Windows 7 Professional 7601 Service Pack 1] 
Server=[Windows 7 Professional 6.1] 
tree connect failed: NT_STATUS_ACCESS_DENIED 
Anonymous login successful 
Domain=[WORKGROUP] OS=[Windows 7 Professional 7601 Service Pack 1] 
Server=[Windows 7 Professional 6.1] 
tree connect failed: NT_STATUS_ACCESS_DENIED 
tarExtract: Done: 0 errors, 0 filesExist, 0 sizeExist, 0 sizeExistComp, 0 
filesTotal, 0 sizeTotal 
Got fatal error during xfer (No files dumped for share Users) 
Backup aborted (No files dumped for share Users) 
Not saving this as a partial backup since it has fewer files than the prior one 
(got 0 and 0 files versus 0) 

The configuration settings are: 

$Conf{XferMethod} = 'smb'; 
$Conf{SmbShareName} = 'Users'; 
$Conf{SmbShareUserName} = 'someuser'; 
$Conf{SmbSharePasswd} = 'somepasswd'; 
$Conf{SmbClientPath} = '/usr/bin/smbclient'; 
$Conf{SmbClientFullCmd} = '$smbClientPath \\\\$host\\$shareName 
$I_option -U $userName -E -N -d 1 -c tarmode\\ full -Tc$X_option - 
$fileList'; 

Executing the SmbClientFullCmd manually from a terminal window results 
in a successful run (after substituting for the parameters 
appropriately). 

Changing the SmbClientFullCmd to 

$smbClientPath //$host/$shareName -A /some/path/.auth -E -N -c 
"tarmode full" -Tc - 

also fails when run by BackuPC (but not when run from the command 
line), but no useful information is provided in the log except: 

Started full backup on pavilion (pid=24547, share=Users) 
Backup failed on pavilion (No files dumped for share Users) 

The host being backed up is Windows 7: 

[root@spectra ~]# smbclient -L pavilion -A /home/amachina/.smb.auth 
Domain=[PAVILION] OS=[Windows 7 Professional 7601 Service Pack 1] 
Server=[Windows 7 Professional 6.1] 

Sharename Type Comment 
--------- ---- ------- 
ADMIN$ Disk Remote Admin 
C$ Disk Default share 
D$ Disk Default share 
E$ Disk Default share 
IPC$ IPC Remote IPC 
print$ Disk Printer Drivers 
Users Disk 
Domain=[PAVILION] OS=[Windows 7 Professional 7601 Service Pack 1] 
Server=[Windows 7 Professional 6.1] 

Note that original error message states that "anonymous login" was 
successful, but the intent is to login to the SMB share using the 
configured username and password. All attempts to mangle the 
parameters to force a login of a specific username/password 
combination fail from BackupPC (but work when executed from the 
command line). 

Anybody have any suggestiions?

Check your samba version.  There are reported problems with Win7 and samba for 
older versions.  A google of samba and windows 7 should help you find a site.
