If you think it's just adding up similar tools, you're pretty wrong. I've only used kopia briefly and it had a bug where I couldn't simply read files from its GUI, so I'd take it it's still doing basic implementations but all the tools you mentioned have varying degree of reliability and performance as well. You can easily Google around and see how restic takes huge memory and is slow to restore on larger repo, duplicity being unreliable and you'll find less of those reports for borg which I believe is the only open source tool of the kind that is reliable and doesn't stall on restoration. I want to use multiple implementations for doing a backup towards multiple remote targets in case one implementation has a corruption bug but so far my research only shows it's better to just use borg twice to different remote targets than use another implementation that could be unreliable. duplicacy also takes lots of memory to the point of freezing up a machine with 2GB+ free ram while taking medium sized repo that is only in the range of 50GB with many small files. (Not to mention I don't like its per machine license which can be costly if you handle many small servers.) Backup tools are something that is so sensitive about its reliability. It must be working from the beginning as it's too late when your backup data was corrupt but you only realize that when your original data is already inaccessible as not many people do backup data integrity check frequently. Reading on its feature list doesn't mean much but do yourself a favor and check for GitHub issues, check the forum for bug reports and maybe even Reddit and figure if they're fighting primitive bugs or not. You should rely on a solid tool than just one of the remote backup tool, like using rsnapshot locally first. It uses rsync and hard links, which is quite hard to break. Here are a few reports on instability for a few tools. 1. https://forum.rclone.org/t/rclone-as-destination-for-borgbackup/12717/9 https://forum.rclone.org/t/rclone-as-destination-for-borgbac... 2. https://www.reddit.com/r/unRAID/comments/eg0zpe/duplicati_seems_too_fragile_for_realworld_use/ https://www.reddit.com/r/unRAID/comments/eg0zpe/duplicati_se... 3. https://forum.duplicati.com/t/is-duplicati-2-ready-for-production/4714/6 https://forum.duplicati.com/t/is-duplicati-2-ready-for-produ...
