I have been using BackupPC for about two years to backup several Windows 2003 servers via SMB (BackupPC is running on Fedora FC8 and was built from the source 3.1). It rocks along and does its thing. A few weeks ago, it stopped backing up much of anything. If you go into the log, you see where it gets a few files
 
For instance, a few minutes ago, I told it to do a full backup of a server. The server has about 50GB of data but the output from the backup is shown below.
 
2008-05-31 14:45:22 full backup started for share C$
2008-05-31 14:45:40 full backup started for share D$
2008-05-31 14:46:05 full backup started for share W$
2008-05-31 14:47:21 full backup 196 complete, 2349 files, 393719952 bytes, 183 xferErrs ( bad files,  bad shares, 183 other)

 

 

If you go to the log, you will see this:

 

File /data/BackupPC/pc/truck/XferLOG.196.z (Extracting only Errors)

Contents of file /data/BackupPC/pc/truck/XferLOG.196.z, modified 2008-05-31 14:47:21 (Extracting only Errors)

 

Running: /usr/bin/smbclient \\\\truck\\C\$ -U ourdomain/auburntiger -E -N -d 1 -c tarmode\ full -Tc -

Xfer PIDs are now 11497,11496

tarExtract: Done: 0

 

This is typical of all computers that it tries to backup.

 

 

Any idea?
