Four ways to fix the 'Can't connect to a current Time Machine backup disk' error

After we established the possibilities that may cause your Mac can't connect to a current Time Machine backup disk, you can start to fix this issue with the listed solutions available to us.

Check the Time Machine backup disk in Finder

Finder is the default file manager and graphical user interface shell used on macOS. Like File Explorer on Windows, you can use it to check the connected external hard drives on your Mac and access all the files on external disks, Macintosh HD, or network volumes.

Thus, open Finder in Dock to check whether your Time Machine backup disk is showing up on the list of the Locations tab. If not, your disk could be off, disconnected, or defective.

Reconnect the backup disk

The improperly plugged external storage device could cause the issue of disconnectivity. If you use an external disk as your Time Machine backup disk, it is possible that the disk is disconnected so that your Mac can't connect to your Time Machine backup disk.

So you need to remove the backup disk from your Mac, then replug it to your Mac. Ensure your backup disk is connected to your Mac correctly and turns on with the power source switched on.

Verify the network connectivity of the network backup disk

A network disk is a shared storage device that can be accessed by two or more computers on the same network. You can set up an external disk as a network disk to make a Time Machine backup.

Accordingly, as we mentioned before, one of the reasons that your Mac can't connect to the Time Machine backup disk is the disconnection of your network. This is also the main reason why Time Machine backup fails after upgrading to Sequoia.

If you use a network disk as your Time Machine backup disk, make sure your Mac has a stable and intact network connection to verify backups in Disk Utility.

Allow access to the Time Machine backup

The main reason that causes your Mac can't connect to a current Time Machine backup disk might be the lack of permission to the backup database folder. So you can check whether your Mac is allowed to access the Time Machine backup in Finder.

If you can see a red stop sign in the Backups.backupdb folder and can't open it, it indicates you don't have permission to access the Time Machine backup. Now that you can use Terminal to grant permission to access the Time Machine backup and make your Mac reconnect to your Time Machine backup disk.
