I think the best solution is to use this extension https://github.com/yii2tech/file-storage, because has a lot of support

[[\yii2tech\filestorage\local\Storage]] - stores files on the OS local file system.
[[\yii2tech\filestorage\sftp\Storage]] - stores files using SSH2 SFTP.
[[\yii2tech\filestorage\amazon\Storage]] - stores files using Amazon simple storage service (S3).
[[\yii2tech\filestorage\mongodb\Storage]] - stores files using MongoDB GridFS.
[[\yii2tech\filestorage\hub\Storage]] - allows combination of different file storages.
