What does "Nothing was backed up — the set has no readable sources" mean?
Short answer: None of the set's folders could be read — moved, on a disconnected drive, or blocked by macOS. Check the folders exist, connect the drive, grant Full Disk Access, then retry.
None of the folders in this backup set could be read — they were moved, renamed or deleted, sit on a drive that isn't connected, or macOS blocked access to them.
### What to do 1. Open the backup set and check its folders still exist. 2. Connect any drive they live on. 3. Make sure Storage Studio has Full Disk Access for protected folders like Documents and Desktop. 4. Run the backup again.
