This reminds me of my posts on reddit 3 months prior, it all started with Noob here🤣, so even I am a noob. Or you can say you are on Lemmy and not reddit, so I wont call you or myself a noob anymore, as noobs are still on reddit😉.But we all learn bits with time. I read those posts too, but gave it a shot anyway and its been 4 months of using Duplicati, still running without any issues.

I do randomly test it as well, but copy/pasting my stuff and then deleting it from original location, and use Duplicati to restore and works well everytime. I did those tests every 7days for 1st month, but after that it has been 3 months where I do similar tests randomly either 20 days or monthly. And still doing good.

Key part to remember while Duplicati is Versioning, I keep atleast 5 versions of backup (daily backups), and the things I backup are mainly Photos or password manager data. So even if I get a corrupted back up and even lose my system. I'll still have the 4 other backups which ain't very old, as its daily backups with 5 versions so, 1 backup per day for last 5 days. So 90% chances are I won't lose the data, but in case even if I do it would negligible.
