I'm working with Windows NT and MS SQL, but some important data in our organization are on Oracle 7.3 which run on the UNIX box. After the last crash of Oracle server when we lost a whole day's work I have a quarrel with our administrator. He explained that on UNIX there isn't a way to schedule the command execution at later time, but during the working hours he doesn't have a time to run the log backup of database. Living all my life in Windows world I don't believe him.
So my question: is there a way to make schedule of running log backup automaticaly either by UNIX or Oracle means?
If yes then how, if no then why you're using them (UNIX and Oracle).
