TM Sparse bundle version: After failed verification all history is lost and a new backup created. If the history is valuable then editing of the sparse bundle may be warranted. I understand it is possible but it is not simple. I didn’t save the corrupted file. TM Backups.backupdb version: Data looks as if it could be easily edited to remove single or multiple days. I did not investigate the process for doing this.
