after update macOs to 12.7.5 I always get Time Machine error: an error occurred while preparing the backup.
On 21/05/24 I updated macOs to 12.7.5. Since then Time Machine does not backup anymore, the latest backup is 20/05/24 on the backup disk and 15/05/25 on Time Capsule.
I have a Time Capsule (2T with 1,03T available) and a backup disk (2T with 1,16T available) , with both it starts finding changes.
On Time Capsule after 128.766 changes detected it stops and starts cleaning up.
On backup disk after 97.000 changes detected it stops and starts cleaning up.
I hade the same results starting on "safe mode".
How should proceed to resume correct backup?
Thank you
