I've been trying to back up my hard drive to my external hard drive via Time Machine. I keep getting the error message "Backup Disk Not Available." I haven't been able to back up in three weeks. I'm running Monterey OS 12.5. Any help is much appreciated.
MacBook Pro 13″, macOS 10.15
If it's a new drive, it's likely formatted NTFS; a Windows format. Using Disk utility, erase and format the drive with an Apple format.

Have you been able to back up before with this drive?
