Hi,

As the title suggests: what are alternatives to syncthing that are basically fire and forget, works on multiple device types, and just focuses on file syncing?

I've had over the months the weirdest problems with syncthing, and lately I noticed some of my photos got corrupted, which is an absolute no no for me. I use syncthing currently as a easy automatic backup of documents, photos and other files, between my PCs and my phones (they all send only to the server. Folders are not shared with other devices).

Is Syncthing my ideal backup application?¶

No. Syncthing is not a great backup application because all changes to your files (modifications, deletions, etc.) will be propagated to all your devices. You can enable versioning, but we encourage you to use other tools to keep your data safe from your (or our) mistakes.

Sync is sync. Sync is NOT backup.

This is why you should have file history versioning on. With backup this is a most.

Would syncing your backup directory work? Like take snapshots of your system, dump the snapshots all in a single directory, and sync it to an off-site location?

[–] milicent_bystandr@lemm.ee 1 points 4 days ago

Kind of. That improves your backup safety, but doesn't mitigate all the risks. E.g. if you accidentally delete everything from your backup directory, then all those deletions also happen on the sync'd one.

No, re-read above.
