When everyone is responsible no one is responsible. The "designated" DBA may also be an end user but one person must be the responsible party.

There are plenty of competent consultants that can VPN in and do the work if it is just about money.

Are they going to verify the backup took place? Are they going to look at the alert log and understand what they are reading?
Are they going to check gv$backup_corruption? Could they possibly restore and recover if they had to?

But ultimately it is about what I said ... if everyone is responsible then no one is. And unless someone is licensing an Oracle database to hold their mother's cookie recipes, granting SYSDBA to end-users is not a winning solution to for anyone other than an attorney.

You may view yourself as a system "user" but to call yourself an "end user" is to torture the phrase.
