I’ve got a Synology DiskStation DS416 NAS on our home network. I use Crashplan for backing up to the cloud. And except for one MacBook Pro running OS X, all our machines are running Windows 10. This post is to share some of the key parts of the configuration to make it all work. (After having to go through this myself a few times over the years, and forgetting some part of it, I’m writing this for my future self as much as anyone else.)
I run Crashplan on my primary desktop PC. While I’ve seen it’s possible to run Crashplan headless directly on the NAS, I’ve just stuck to running it on my PC and expose the shares on the NAS to Crashplan by creating directory symbolic links:
mklink /d music \\mynas\shares\music
To get Crashplan to see those shares though, you have to install it in Per User mode. If you installed it for Everyone already, you’re going to need to uninstall and reinstall it in single user mode. Until you do this, Crashplan will show your data as “MISSING.” This was the part that I just wasted an hour on after doing a clean install of Windows on my main PC and having it reconnect to Crashplan.
The other bit I just learned about is Windows’s Credential Manager. I’ve never had a need to use it, but it allowed me to specify a NAS account to use whenever I use the symlinks I created. To do that, you just open up Credential Manager on the PC, click on ‘Windows Credentials’, click ‘Add a Windows credential’, and provide your NAS’ name (e.g., ‘\mynas’), user name, and password. Reboot and you should be accessing the NAS shares now with the desired access levels.
