I’m a new user of a WD EX2 Ultra. I setup a Time Machine share, configure it in the NAS Settings, tell my Big Sur laptop to backup there, and it runs for 100 GB then stops. When I try to tell the backup to recommence, Time Machine reports “Looking for backup disk…” and never finds it. I get an error to try again when the NAS is available.
If I go into “select disk,” my Time Machine share shows up twice, once with “_smb_tcp” appended to the device name, and the user/pass prepended.
I’ve tried this several times, deleting and recreating the share. I’ve tried it logging into the NAS with my username/password, and also with the NAS configured to be public and logging in as Guest. I get the same thing every time.
