Is there backup repair function in the backup?
I mean that can a repair data be added to archive for the case if it will be insignificantly corrupted? Then when you verify the backup and find it’s corrupted, you just repair it using the repair data in the backup.
Or maybe there exist other ways to repair backup if it is corrupted?
No, there isn’t a way to recover a corrupted backup.
If a backup gets corrupted, the only thing that can be done is to recover as much data as possible from it (data that is stored in non-corrupted areas of the backup).
Thank you for your answer.
This is a necessary option worth paying attention.
It deserves to be included into the wish list.
