I own and EX 4100 and I’m thinking of adding a PR 4100 to my network. I will want to back up the PR4100 to the EX 4100. Will I need special software to be able to do that?

Yes you can with Remote Backup App. You need to add it, it’s not automatically installed. I am currently backing up PR4100 to a DL2100 locally on my network.
But I intend to take the DL2100 to a family members house and keep it as off-site backups.
If doing it to another location, you need to port forward on the remote router to your drive. You need to set up the remote drive with a static IP on the remote network.
You will also need to know the IP address of the other location and it may change from time to time. They can use whatsmyipaddress.com to find out what it is.
When you setup the job, you need to use the IP address of the modem/remote router and on that router is where you have to port forward to a static IP on their network to your backup drive.

If you want to backup the PR4100 to the EX4100, you can use a built-in feature called Rsync that is available on both devices. Rsync is a utility for Unix-like systems that syncs files and directories between two locations over network.
Here are basic steps required to set up rsync-based backups:
- First ensure that your PR 4100 has SSH access enabled so it can communicate with your EX 4100 via secure shell (SSH).
- Log in to your EX 4100 using ssh client like Putty or any other capable of running rsync command.
- Install Rsync Server package if not already installed from Synology Package Center .
- Configure an rsync module on the EX 4100 by adding folders/drives which require backing up.
- Configure corresponding rsync task(s) on PR 4100 specifying source/destination paths, schedule etc as per requirement
- Run backup job manually first time around and then monitor logs for errors /warnings.
With proper configuration , You should be able to achieve back-up functionality easily without need for any special software beyond what’s included out-of-box .
