I have tried to set up, run full backup and then continue running backups at least 3 times for my mabook air and everytime the first backup completes successfully, but then for subsequent backups I get the sparsbindle cannot be accessed error.
I have rund disk utility on the bundle, it’s fine, checked i’m on latest firmware, I am, checked setup and disc permissions, all fine.
Can someone please help or is the duo just not compaptible with time machine (as it is advertised it is?)
