Run this if you'd like to import your media_store files from a previous installation of Synapse.
Before doing the actual data restore, you need to upload your media store directory to the server (any path is okay).
If you are Storing Matrix media files on Amazon S3 (optional), restoring with this tool is not possible right now.
As an alternative, you can perform a manual restore using the AWS CLI tool (e.g. aws s3 sync /path/to/server/media_store/. s3://name-of-bucket/)
Note for Mac users: Due to case-sensitivity issues on certain Mac filesystems (HFS or HFS+), filename corruption may occur if you copy a media_store directory to your Mac. If you're transferring a media_store directory between 2 servers, make sure you do it directly (from server to server with a tool such as rsync), and not by downloading the files to your Mac.
Run this command (make sure to replace <server-path-to-media_store> with a path on your server):
ansible-playbook -i inventory/hosts setup.yml --extra-vars='server_path_media_store=<server-path-to-media_store>' --tags=import-synapse-media-store
Note: <server-path-to-media_store> must be a file path to a media_store directory on the server (not on your local machine!).
