❌ Not the solution anymore, use the GIT project for a fast, reliable and easy back-up, automated if you want: 
Creating  a little noise in the Apple Script/Back-ups discussion. First of all, thx EVERYONE for thinking along, reading along, trying stuff and suggesting new idea's, other methods and spark creativity!
My original question was: How to make proper and automated back-ups of Evernote v10 data [on Windows]? [SOLVED]
Here are my final measurements/results from my new-Backupery tests, with the non-legacy version of the app, not relying on a local installation of Evernote anymore, using the Evernote API and doing a fresh download of your data, instead of using local data cached on your computer as the old Backupery did:
My final conclusion: Backupery new version (published april 2023) is suitable for back-ups of my Evernote data [on Windows], of a little of 10+ GB of ENEX resulting file,15.000 notes. I'll get back if the restore test fails. The speed is too low. I believe because of slow API answers from Evernote servers itself, though I am not 100% sure. I tested on quite fast laptops and with WIFI or with wired Internet.    Backupery can be found here: https://www.backupery.com/products/backupery-for-evernote/   It meets my criteria of a good back-up from my point of view and I can herewith check all of the following boxes, when Backupery is used in an automated script, and movement of resulting encrypted (via GPG in a timed batch file) files to Synology Cloud C2 back-up chain and Dropbox:  (1) []local  (2)[]off-site (3) []offline (4) []duplicate (5) []encrypted (6) []AVG-proof (7) []restored+verified+interval (8) []retention+timeframe (no unique filenames) (9) []full must-have+frequency (10) []incremental if needed as add-on (11) []recovery duration In addition to that it is easy and trustworthy to set up, rely on as little human actions and reminders as needed. 
This conclusion results from the following report:
Newer machine on wired Internet:
On a newer laptop with wired 1gbit wired Internet (a 2023-03 Microsoft Surface Pro 9 i7 | 32GB |1TB) with Backupery NEW  it needed 1,68 seconds per note which for my 15.000 notes resulted in 10,33GB ENEX files and 5,35GB HTML (that option was enabled) it took 6,9 hours to complete *) note that I use comma for decimals and point for thousands 😉   Older machine on WIFI Internet: On an older (but good) laptop with WIFI Internet (a 2019-01 Asus RX362F i7, WIFI then 1gbit glassfiber) with  Backupery NEW it needed 2,95 seconds per note which for my 15.000 notes resulted in 10,33GB ENEX and 5,35GB of HTML files (that option was enabled) it took 12,3 hours to complete conclusion: my older laptop via WIFI takes 175% of the time compared to my faster wired Internet laptop. *) alternative setup measurement: older machine ENEX per notebook, without HTML via WIFI: 1,4 seconds per note, 5,9 hours total   I also tried: *) alternative setup measurement: older machine ENEX per notebook, without HTML with seperate ENEX per note  «⚠️🟡 CHECK started: 20230513 1423~?~ gestart   However, that job stopped with an errormessage: Evernote usage has been temporarily exceeded. Your data will be received in 37 minutes.   I guess I have been making too many API calls/back-ups past 24 hours. 😉

Same here. I work like a Ninja in the legacy Evernote, changing hundreds of Evernotes during a day, in groups, one by one, changing tags VERY fast, organisering and while managing my company. I switched back to legacy very fast. See also: 
Tip: I never used the insert date/time of Evernote, I have always used PhraseExpress to do this and it's more customizable and wonderful. I use qqd for the date, e.g. 20210307  and qqt to also add the time. This besides MANY more shortcuts to insert all kinds of text/structures.
