Can anyone out there explain what may cause this???...  
My Development VMware Gateway:  
=Version: 8.1.20  
My Clients Production Backup made two days ago at clients site...  
=Version: 8.1.20  
When trying to overwrite my development copy back at the office I get the following...  
Validation Error: The selected backup is from a future version and cannot be restored in this version of the Ignition Gateway.  
I looked at the date time of my development virtual machine and dont see there is a fake test date there.... What could this be? Thank you for reading this post

If you make a copy of your GWBK and rename with `.zip` extension, you should be able to unzip it and inspect the contents of the `backupinfo.xml` file that is included. That should give you more details on the specifics of the backup that was taken.

It will look something like this:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<gateway-backup>
	<version>8.1.20.2022082313</version>
	<timestamp>2022-12-16 16:08:29</timestamp>
	<backup-type>DATA_ONLY</backup-type>
	<ts>1671228509119</ts>
	<edition></edition>
</gateway-backup>

```

Also, if you're on macOS/Linux, you can output this directly with the following in the terminal:

```bash
unzip -cq /path/to/gateway.gwbk backupinfo.xml

```

You can open the gwbk directly as well in a zip program like 7zip

Linux generally doesn't give a rip what file extension is present, on anything. It looks into the file to determine what it is, and acts accordingly. I click on a gateway backup and it opens in Ark, like any other compressed file.
