File Backup for Oracle Database Files

We backup the Oracle database files (on the OS - Windows/Linux) presenting them through file system through NetBackup. We have Oracle native datapump backups also run.

The file system size with database files are huge. And we are not sure, if the flat file system restoration would work for the Database. If this will not work, then we will go with the datapump backups alone ignoring the file system level backup.

Can you please clarify on this?
