I am not entirely sure what Dropbox does (especially the communication with its server: it is encrypted using SSL, I think.), but as someone mentioned that there are peer-discovery and communication.

LAN Sync #FeatureRequest owncloud/core#26752.

Would it be possible to consider this feature? Thank you!įor reference, other links where this feature is requested: And a lot of discussions have already started, both on owncloud and Nextcloud, but it looks like there's no activity anymore for years ( nextcloud/server#7092, nextcloud/server#8331, owncloud/client#230). It is a cool and efficient existing Dropbox feature ( ). In order to optimize this, we'd like to have the ability to sync over a LAN both with the server if it's on the LAN, and especially with other clients on the same LAN, who have already synced. In addition, in a climate change perspective, it would be useful to limit bandwidth usage over large distances to save energy.

I'm in Africa and we have both a slow and expensive bandwidth (illimited plans are very rare).
