@mathew @mastodonmigration oh, please be very careful with syncthing. Make backups on both sides of the sync folder pair before setting up the sync or you might easily loose data. It works very well and is snappy, but you can just as snappily delete many files at once, if you're not careful during setup, not understanding how it works.

Example: if you want to sync some file directory to an empty directory another device, be sure to start on the device with the files. Don't start from the empty directory.
Also, don't sync two directories with each containig different files. Only one set of the files will be retained and all the other files will be deleted.
Always start from the place containig files and always sync to an initially empty directory. You can add files on either side after sync is set up, the initial sync is completed, and the system is idle.
