They have a sync that actually works pretty well. As the product is still beta you can donate and get access to the sync service.

I first tried zerotier but ran into some weird issue...don't recall what it is now....and then tried tailscale and was up and running in like 15 mins. But I see others have had the absolutely opposite experience from mine where tailscale wouldn't work and zerotier would. I think they're both great products.
I personally never bother with disk image or backing up the OS for my own stuff. I find that usually by the time I think its time to restore a bunch of data my Linux install is full of kludge and crap so easier just to reinstall the OS and then restore the configs and data from backup. That is also when I'll usually look at playing with another distro. Keeps me learning new things.
Now things like VMs are a different matter and I'll usually back them up completely.
Always always always have 3 places where you store your data. Your main data store. Another storage location and then one offsite. And like others have said...check your backups occasionally to make sure you can successfully restore from them.
Thats funny. They have 4th of July sale but the black friday prices are better.
I'll second DuckDNS. Works great. Configured on my firewall to automatically update.
They're owned by Microsoft?
Like everybody else here said...audiobookshelf is da bomb. I had an audible subscription for a while and found myself without the time to really listen to enough audiobooks to make it worthwhile so I cancelled. I know I could still access the audiobooks I purchased but I'm always concerned with these companies suddenly having a disagreement with a publisher and nuking a whole pile of media I paid for so I figured out how to download my purchased audiobooks locally to be listened to via audiobookshelf. Worked great.
If you're looking at trying something different give XCP-NG a try. Its a fork of XenServer. Great piece of software. Nothing wrong with Proxmox either.
You could also look at Mikrotik. They have some amazing hardware with every bell and whistle you could ever want
I look forward to Grumpy Old Geeks Podcast every week. Two old timers from the tech industry. tagline for the show is "What went wrong on the internet and whose to blame."
