"I'll take a bit of kibble and EAT IT!!"
Do you run an antivirus or just the built-in? Windows Defender, after an update, has been known to peer at Jellyfin and say "Absolutely Not".
If you are all linux, perhaps you'd like Borg. It's pretty easy to set up, and perhaps it offers the de-duplication you crave. It's also got some GUIs you can run, if you are into that kind of thing. If you don't feel inclined to use any backup software, then using rsync over ssh (scp, yes) instead of SFTP is a solid way to go.
I personally run a ProxMox cluster. I run both Windows and Linux servers. I perform local full-VM backups using the hypervisor to a USB disk. That gives me a fast way to restore VMs if I need to. I also run Veeam, which handles the offsite copy and provides granular file restores. It's nice because the community edition supports hardened disk immutability, which can help prevent ransomware attacks and Unfortunate Incidents. That just runs over SSH, and installs a Veeam agent/repo on the remote linux box.
It's not quite as full featured as Evernote, but I like Joplin. It can sync using Nextcloud, OneDrive, WebDAV, and other services. It's end to end encrypted and works well on Android!
Talk about a massive wave. You got it, a wave period of decades. Space is big, mind-bogglingly big....
Whoa! This truly whips the llama's ass! Winamp forever!
I....I got rejected, but it's okay! I rolled my own instance and subscribed anyway!
Yeah, you should probably pluck it and plant it. It'll help focus energy to the roots and leaves.
I've just thrown in. I hope to see this community thrive and bring others up with it!
Which is somewhat BS, since we have a perfectly good Olympic Peninsula here in Washington State that it was certainly named after.
