ORA-19675: file [string] was modified during proxy copy
Cause: A proxy backup of the specified file failed because the file was brought on-line or otherwise modified while the proxy backup was in progress. This file was off-line or read-only when the backup began, so the file was not put into hot-backup mode, therefore no modifications are permitted while the backup is in progress.
Action: Take another backup of this file.
Error Type: ORA
