Thank you! I do love rclone a great deal, and need to start using it more. I mostly use rsync right now because I've got some Contabo storage instances and ssh is already set up, so it's nice and easy, and I've already got the rsync commands burned into memory from decades of use :-) I also typically rsync with the same command to an external hard drive for an on-site backup.
Great tips! I'll definitely be using your tar command
Oh, that reminds me. When I had an Android (I already regret my iPhone) I used termux to write a very basic script to rsync data to machines and do so based on if connected to WiFi (with whitelisted SSIDs). Pretty easy to write and then schedule a cron job. Can be nice to put that onto other peoples devices and give them automated backups. Makes it FAR easier to do the 321 backup strategy. Also pretty easy to build a tracking app for a lost phone that way (like if haven't connected to home WiFi in x days send you an email). Both work really well when also using tailscale.
