If you don’t plan to make backups frequently, and want to restore to the same controller, PC Controller (small application included in giant Simplicity Studio download) will work fine.
If you want to backup to a Gen5+, Z-Wave JS UI would be required and both your ZMEEUZB1 and Gen5+ Z-Wave SDK versions will need to be at least v6.81. For Gen5+ that would be their firmware v1.02 (1.2), not sure for Z-wave.me.
Switching to Z-Wave JS UI is arguably easier to do than create an SI Labs account, login and agree to their TOS, and download Simplicity Studio.
Although, I’d be hesitant to advise switching to the Z-Wave JS UI add-on at this very moment because it is currently almost a month out of date of upstream, and is missing some possibly important driver fixes, compared to the Z-Wave JS add-on. These fixes aren’t needed for everyone though, just depends on the network.
