Why can’t I add a network location to Time Machine on my Mac?
I’ve been trying to set up my Mac to back up to a network location using Time Machine, but I keep running into issues. I’ve followed multiple guides and checked different settings, but the option to select a network drive just doesn’t seem to work. When I navigate through the Time Machine preferences and attempt to add a network location, it either doesn’t appear or I get an error message. I’ve ensured that my network drive is properly connected and accessible from my Mac outside of Time Machine. I can read and write files without any issues, so I’m confused about why Time Machine isn’t allowing me to use it as a backup destination. Additionally, I’ve confirmed that my Mac and the network drive are on the same network, and I’ve tried restarting both devices multiple times. Despite all of these steps, Time Machine simply refuses to recognize the network location as a valid backup destination. This issue is becoming quite frustrating as I need a reliable backup solution that involves network storage.

It could be that your network drive uses a different protocol. Make sure it supports either AFP (Apple Filing Protocol) or SMB (Server Message Block). Time Machine has issues with other protocols. Try switching the protocol of your network-attached storage (NAS) to one of these in its settings, and it might start to work.
I’ve faced the same problem. Adjusting router settings resolved it for me. Log into your router’s admin page, locate the Quality of Service (QoS) settings, and either disable them or prioritize your network drive’s IP. After saving and restarting your router, attempt to add the network location again. This can often resolve such connectivity issues.
Try adding the network drive manually through Finder first. Open Finder, navigate to Go > Connect to Server, and type in the network address, like smb://your-server-address. After connecting and mounting the drive, go back to Time Machine preferences and try adding the location again. This method has helped me several times.
Disabling and re-enabling the ‘Back Up Automatically’ option in Time Machine might do the trick. Uncheck ‘Back Up Automatically’ in Time Machine preferences, select your network location again, and then re-enable the automatic backups. This step has helped reset and recognize the backup disk for many users.
Sometimes connectivity is the culprit. To ensure consistent connection, open Finder, browse to your network drive, right-click, and select ‘Make Alias’ to create a shortcut. Place this alias on your desktop and ensure it’s connected before initiating the Time Machine backup. This method has made my backups more reliable.
Permissions on the network drive might be causing the problem. Check if the user account on the network drive has appropriate read/write permissions. Access the NAS settings, verify, and adjust the permissions accordingly. Once the permissions were properly set, my Mac detected the drive without any issues.
Here’s a solution that worked for me: Check your Mac’s firewall settings. Open System Preferences, go to Security & Privacy, and then the Firewall tab. Click the lock to make changes and turn off the firewall temporarily. If this helps, turn the firewall back on and add Time Machine to the list of allowed apps. Sometimes, network backups can be blocked by firewall settings.
Make sure your network login credentials are saved in your macOS Keychain. Open Keychain Access from Utilities, add a new password item for the network drive with its address and credentials, and save it. Connecting through Finder and then retrying Time Machine might work as saving these credentials ensures proper access.
