Synology recently made their C2 Backup service available worldwide. The C2 backup service requires Hyper Backup, so it is only those of us with a Synology NAS. It backs up the data to a data center in Germany. C2 Backup is a subscription-based service, although you start with a 30-day free trial. I provided a detailed overview of the service here.
If you’ve ever used Hyper Backup, you are familiar with the C2 Backup setup and how it will work. There are limitations around scheduling and versions, depending on the plan you choose.
If you don’t already have the Hyper Backup package installed, install it then click the icon in the Synology main menu to start it.
Once Hyper Backup loads, click the “+” in the lower left to create a new backup task. Then select Data backup task from the backup menu.
Select Synology C2 cloud backup as the backup destination.
At this point, you will need to sign-in to a Synology account. These procedures will show the process if you already have an account. If you don’t have an account, you can select Register a Synology account from the login screen.
Since you’ve never used Synology C2 backup, you will receive a prompt for a free trial. The only option is to take it. You will be prompted for a credit card and to select a plan. You must cancel before the 30 days is up if you don’t want your credit card charged.
Select the plan you want to use.
Enter your credit card information.
Confirm your choices.
Now give Hyper Backup the authority to access your Synology account.
The default settings are shown. Feel free to change them to suit your needs.
I like to use client-side encryption for anything going to the cloud, so I enabled it and entered a password. Optional, but recommended. Be sure to remember the password and save the key file that is generated.
Now we get into to meat of the backup configuration. You’ll be prompted to select a directory to contain the backup. This is a directory created in the C2 cloud. The default is unique to the destination (if you have already done backups, it won’t repeat a directory name) and I typically accept it. If you plan to do multiple backups to the C2 cloud, you may want to write down the destination for each backup.
All your shares will be listed. Check the ones that you want to back up. Initially, I recommend starting with one small share just to see how things work. The lock next to a share name indicates it’s an encrypted share and the status, mounted (unlocked) or not mounted (locked). Encrypted share must be unlocked (mounted) at the time the backup runs to back them up. Hyper Backup cannot unlock a locked (unmounted) share during backup. I often put encrypted shares in a separate backup task just to keep things orderly.
Next, you’ll pick the applications to back up. If the application says Yes in the “Disabled” column, the application will be shut down while it is backed up. The app is only shutdown while it is actually being backed up, not the whole time the backup task is running. If there’s a share listed in the “Shared Folder” column, then that share will be added to the shares selected for backup even if you didn’t pick it on the previous screen. Note: while needed shares are automatically selected for backup, unselecting the app will not unselect the share, even if it was a misclick that you immediately fixed before leaving this screen.
Finally, you’ll be prompted to tell Hyper Backup to backup immediately or to wait until the scheduled time.
You will return to the main Hyper Backup screen with the new backup task selected. If you selected yes the backup has started, and the status is displayed.
The status will change as the backup progresses.
