Amazon S3

To connect your Amazon S3 buckets to Nextcloud, you will need:

  • S3 access key

  • S3 secret key

  • Bucket name

In the Folder name field enter a local folder name for your S3 mountpoint. If this does not exist it will be created.

In the Available for field enter the users or groups who have permission to access your S3 mount.

The Enable SSL checkbox enables HTTPS connections; using HTTPS is always highly-recommended.

Optionally, you can override the hostname, port and region of your S3 server, which is required for non-Amazon servers such as Ceph Object Gateway.

Enable path style is usually not required (and is, in fact, incompatible with newer Amazon datacenters), but can be used with non-Amazon servers where the DNS infrastructure cannot be controlled. Ordinarily, requests will be made with http://bucket.hostname.domain/, but with path style enabled, requests are made with http://hostname.domain/bucket instead.

Legacy authentication is only required for S3 servers that only implement version 2 authentication, by default version 4 authentication will be used.

See Configuring External Storage (GUI) for additional mount options and information.

See External Storage authentication mechanisms for more information on authentication schemes.
