Database
Contact your DBA and use a backup utility such as RMAN to perform nightly hot

Another crude way to take a backup of your database is to use the Oracle Data
Pump utility commands such as
expdp
that can be used to export the database
schema and the
impdp
command that is used for importing the dump file to the
database. Because these are the low level database methods, this approach is
more suitable when performing an initial data migration to a fresh installation or
cloning an environment that does not yet contain any business data.
