RMAN Incremental Backup Fails> ORA-19504: failed to create file . . .
Hello, have been running successfully for months then in past 2 weeks getting errors below. ADG environment and am backing up Primary database. If I rename the file that already exists and re-run backup it fails on yet another duplicate name. I have even deleted all backups and re-run, it is ok for awhile then I get these errors again. Any help appreciated!
Thank you .... Carol
