There are several ways to backup views and tables in Oracle:

1. Export and Import: You can use the Oracle Data Pump Export and Import utilities to backup views and tables. You can export the views and tables using the EXPDP command and import them using the IMPDP command.
2. RMAN Backup: You can use Oracle Recovery Manager (RMAN) to backup views and tables. RMAN can backup the entire database or individual tables and views.
3. SQL script: You can use SQL scripts to create a backup of the views and tables by selecting the data and inserting it into a backup table. You can also use the CREATE TABLE AS SELECT (CTAS) command to backup the data.
4. Data Pump: Oracle Data Pump utility can also be used to backup views and tables. You can use the expdp and impdp commands to export and import the views and tables.

It is recommended to have a regular backup strategy in place to ensure that your data is protected in case of any unexpected issues or failures.
