Here is what I do: Level 1 protection: Offline (only on when adding/updating) harddrive. USB Hard disk (non ssd) for example will do. Level 2 protection: Always on Synology NAS at home with Raid 1 between 2 drives Level 3 protection: Google Drive plan with 100Tb. You work only in the level 2, always available in you network You can automate between Level 1 and 2 if you connect the external hd to the nas and click the button to sync the photos. You can automate between level 2 and 3 with synology software alone (in the package manager) I hope this simplifies your life.
