True Image 2018 reporting last backup failed
I''ve not backed up in 2 months but wanted to now after Win 10 2004 update. Though I am getting message - "The last backup failed, The backup cannot be started. Plug in the external drive containing the files for the backup," I DO have the external drive plugged in, it does show the right drive letter, I can see the existing files on the Toshiba if I look, AND I can drag and drop a file from my pc to the F drive. Not knowing what it actually is, I tried "validating" which gave me the green light until I tried to back up again..... What do I do now???? Will I have the same problem if I just updated to True Image 2020? IF I started a completely new FULL+ Differentials backup on the same Toshiba F, would that most likely fail too? With 2018 no longer supported is this the proper vanue to get answers?
