Weird Folder Looping

Having looked more closely at the backup process here, it seems there
are more serious issues I need to examine.

I added the -v flag to smbtar to produce a verbose output, and there
are many cases of the following types of error.  This is between a
linux machine running 2.2.1a, and a solaris machine also running
2.2.1a.

1. This one appears to be a case sensitivity issue.  ICLink and iclink
   are different files, so this warning I understand:

     13487 (  286.3 kb/s) \mgc-c4\bin\rm_ic_readlocks
     11245 (  296.8 kb/s) \mgc-c4\bin\ICLink
File size change - truncating \mgc-c4\bin\iclink to 1469 bytes
      1469 (   68.3 kb/s) \mgc-c4\bin\iclink
      3849 (  101.6 kb/s) \mgc-c4\bin\InstantXpert

2. These ones are more worrying:

Mentor Graphics (mgc) does use symlinks extensively, but the links all
appear correct.  Certainly for the files above that are failing for
some reason.
