I’d like to sync my markdown notes between devices (laptop and phone), which service is better: Nextcloud or Syncthing? Any other important idea I should know?, like latency times, or maximum number of synced devices, what if I edit the same note from both places without internet and then both get connected to a network… For example, I know Nextcloud let me have a history of the notes.
Backups means you have history snapshotted in time.
Nextcloud does have done simple file versioning and a “trash” for deleted files, so you could get some simple protection from mistaken deleted files. But it’s more “best effort” than “designed for backups”.
