Hello, Bacula Users.  I apologize for adding yet another thread to this topic.  I've seen a number of threads that make mention of these Vista problems, and they seem to drop off sometime around mid-2007.  Yet, for me the issues persist, so I'm perplexed.  If someone has a link to the definitive answer(s) to these issues, I'd appreciate your reply.
 
For the client in question, I am using Backula version 2.4.2 on Vista Ultimate 64-bit.  I've been using Bacula for a while now, and have come to enjoy its reliability and configurability.  Unfortunately, I'm in an environment where I must also support Windows, including Microsoft's latest proof that they don't understand upward compatibility: Vista.  Bacula seems to handle the various Linux flavors in the network, and even the XP client seems quite reliable.  However, with Vista (especially Vista 64-bit) we are seeing a significant set of problems.
 
The most costly issue (for me) is the monkey wrench that I started to see surface in this forum about a year and a half ago, where the "junctions" (provided by M$ to point directories to legacy directory names) cause the FD to bail out with messages like:
27-Oct 02:05 m1330-fd JobId 414:      Could not open directory c:/Users/dennis/AppData/Local/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data/Application Data: ERR=The name of the file cannot be resolved by the system.
Not long after this message began to appear on internet, I saw a message (22-Jun-2007) from Kern Sibbald saying that the problem should be solved with a few lines of code.  I've not found much of consequence on this topic in the sixteen months since that time, but the problem persists (at least for me).  Have I missed some key version of the software, or pointer designed to help get past this error?  (It is a big deal in spite of the following observation by Mr. Sibbald: "However, if I am not mistaken, it *is* backing up these junctions, and will probably restore them correctly...")   For me, my backups fail consistently with the following:
27-Oct 02:17 m1330-fd JobId 414: Fatal error: Too many errors.
27-Oct 02:17 luke-sd JobId 414: Job write elapsed time = 00:11:54, Transfer rate = 7.516 M bytes/second
By the way, exclusions do not seem to help resolve this (or maybe I don't know the proper trick).  I have the following in my fileset, but to no avail:
 
FileSet {
  Name = "VistaSet"
  Enable VSS = yes
  Include {
    Options {
      WildDir = "c:/Users/*/Application Data/Application Data"
         <snip>
      Exclude = Yes
      }
    File = "c:/Users/dennis/AppData/"
    File = "c:/pers-data/"
       <snip>
    Options {
      signature = MD5
      compression = GZIP
      _onefs_ = no
      }
    }
  }
 
In spite of this exclusion, I still receive (thousands of) messages like the example from above. 
 
- - - - - - - - - - - -
 
The other issue is VSS.  I've seen threads that indicate this issue was solved long ago (cannot find an example at the moment though - sorry)... but the most recent mention I find of this is from August 8 this year, when Kern Sibbald indicated that a new build was ready - but then the trail runs cold.  Is there any hope of regaining VSS support on 64-bit Vista?
 
Thank you for your time!!!
Dennis
