Specifically I do things like the following:
my $jhost = $_[1];
$Conf{BlackoutPeriods} = []
if $jhost =~ /^(machineA|machine[0-9]|othermachine)$/;
if($jhost =~ /^machineA)$/) {
$Conf{BackupsDisable} = 0; #Scheduled/automatic
}elsif($jhost =~/^ABCD$/) { #Specify hosts to disable
$Conf{BackupsDisable} = 2; #Disable
}elsif($jhost =~/machine[0-9]*$/) { #
$Conf{BackupsDisable} = 2; #CHANGE TO 1 to enable manual
}
etc.
Such logic can be continued for any differences between machines...
Ouch, that looks overly complex... it means mixing configs from
different hosts into the same "script". I'll look into these more
advanced options after I get the simple version working. I'm thinking
something as simple as:

It shouldn't be case sensitive.
And personally, I think I use lower case 'c'
Tell me what the following commands give:
# cygpath -u C:
# cygpath -u c:
# ls $(cygpath -u C:)/..
# ls $(cygpath -u c:)/..
# mount -m | grep "^C: "
# mount -m | grep "^c: "
Results:
$ cygpath -u C:
/cygdrive/c
$ cygpath -u c:
/cygdrive/c
$ ls $(cygpath -u C:)/..
c d
$ ls $(cygpath -u c:)/..
c d
$ mount -m | grep "^C: "
$ mount -m | grep "^c: "
$ mount -m
none /cygdrive cygdrive binary,posix=0,user 0 0
$ mount
C:/cygwin64/root/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin64/root/lib on /usr/lib type ntfs (binary,auto)
C:/cygwin64/root on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
D: on /cygdrive/d type udf (binary,posix=0,user,noumount,auto)
So all seem to work with lowercase or uppercase, but for some reason,
neither works when from the script.
The only "non-standard" thing I've done is all the cygwin tools are
installed to C:\cygwin64\root instead of the default which installs them
to C:\cygwin64\
OK, from re-checking the error and the script, it looks like it's
failing because mount -m doesn't show the c: ...
