My iPad storage is filling up quickly! And the only cloud storage option Illustail offers in 2023 is Dropbox. And the Dropbox free version is only 4.75 GB, which is not enough at all~~

Isn't it a pity that I have a huge Synology NAS but can't use it!?
So this article briefly describes how to use the built-in kit of Synology NAS, no need to type commands, a fool can set it up!


  1. Go to the package center of Synology NAS to install Cloud Sync.
  2. Enable Cloud Sync and add Dropbox backup job.
  3. Make detailed settings.
    • Connection Name is easy to identify by itself;
    • Local path Set the NAS destination folder you want to save;
    • Remote path Set the folder on Dropbox that you want Illustail to upload.
    • Sync direction is set to Download remote changes only.
    • Check Don't remove files in the destination folder when they are removed in the source folder.
