@84Mike, this was a month ago, not sure if you got it figured out?
If you unpack the .tar.gz backup file, you'll find the xln1 file. Here's an example of what I have.
[pre]$ tar -tzvf xln_cm1_011002_20160713.tar.gz
-rwxr--r-- root/root 6180864 2016-07-13 01:10:11 ./etc/opt/defty/xln1
-rwxr--r-- root/root 6180864 2016-07-13 01:10:11 ./etc/opt/defty/xln2
-rw-r--r-- root/root 7 2016-07-13 01:10:02 ./etc/opt/ecs/backup/serverBTMConfigSettings
-rw-r--r-- root/root 1244 2016-07-13 01:10:02 ./etc/opt/ecs/backup/xln_011002_20160713.info[/pre]
Any Linux machine will have the tar/g(un)zip utilities to unpack the backup file. Alternatively if you're a Windows user, you can install the Cygwin environment to get a Linux-like shell environment with more-or-less the same utilities available.
