Hi Adam,
First, you cut out some of the debugging output that would be helpful
in seeing what is happening -- and in particular why shadow drives are
or are not being created.
However, I suspect your problem is that you did not designate any
drives to be shadowed.
According to the comment in my script:
#Note a shadow copy will be created (and pointed to) for every 'letter' drive
referenced in the values of the ClientShareName2Path hash
Specifically, the hash "ClientShareName2Path" is used to identify
the drive letter path for each share name and then to overwrite it
temporarily with the new path relative to the shadow directory.
Below are two different examples.
The first is where the share names are just the letter drives and the
second is where share names correspond to specific folders
$Conf{RsyncShareName} = [ 'c', 'd', 'e' ];
$Conf{ClientShareName2Path} = {
'c' => '/c',
'd' => '/d',
'e' => '/e',
};
$Conf{RsyncShareName} = [ 'Desktop', 'Documents', 'MyData' ];
$Conf{ClientShareName2Path} = {
'Desktop' => '/c/Users/myname/Desktop',
'Documents' => '/c/Users/myname/Documents',
'MyData' => '/d/Data',
};
