An item on my todo list reads "Setup a backup system using Borg". I didn't know about Rclone but it seems very good, so now I want to rename my todo list item as "Setup a backup system using
Rclone". How would you compare these 2 solutions?
The simplest thing you can probably do is use rclone to copy your most important files to a B2 bucket. Enable Object-lock on the B2 bucket to ensure no deletion just to be safe. You can then run rclone on server and from your devices with cron jobs to archive your important stuff. This is not a proper backup as I said, if you rename files or delete unwanted stuff it wont leave on the backup bucket but it's usable for stuff like photos and the like, anything you don't want to lose.
(I lied, simplest thing is actually probably just copying to an external hard drive, but I find having rclone cron jobs much more practical)
