    I am wondering how to setup an external hdd to backup to a nas?

    I have narrowed it down to a Synology DS1515+ with HGST 3tb hdds for the NAS

    The external hdd I was thinking of a Drobo 5DT 15TB OR G-SPEED STUDIO 12TB which are both DAS.

    Id like to work on video editing directly on the external hdd but somehow set daily for it to be backed up to the NAS.

    I think the only way to do it is to plug it in to the nas and manually copy the files. Nas>external works automatically, not the other way around.

    You can use software like Carbon Copy Cloner to schedule the copying of files over to the NAS from the external hdd.

    In a little world of my own
    Synology includes backup software that you can use (Time Backup), or you could use cloud station and mount the cloud station to the external drive. Then you work on the local copy and it will sync it to the NAS realtime. That may cause conflicts though depending on size of files and time to sync so may not be ideal.

    I also use rsync on the Synology to sync the Synology to a TerraStation NAS as a backup. That may work in a similar fashion. It is fast and efficient.
