I can resume this post and say DBAs have three basic tasks: backup, BACKUP, BACKUP!!. Although data integrity is clearly the first job, if the data isn’t good doesnt matter if the database is available or database perfomance is fast.
So first and principal task is Establish and maintain backup and recovery policies and procedures

DBA market can be divided into two groups – juniors and seniors.

sometimes take juniors and train them.
