Hi -- I am running windows server 2012 and would like to backup my users tables and record data. Is there a folder that I need to backup in case I need to recover it at some point?
I probably can create a schedule to run the backup (like with robo copy, etc) but just need to know exact files/folders to backup in case of a disaster, etc.

Thanks much for any help on this!

to maintain data integrity, you can't use OS file copies
You need to use either expdp or RMAN
(or you can write your own tool to dump the data as pure character data to OS file)

The physical structure of an Oracle database is far more complex than your question assumes. You can't back up a table by simply copying a file or a folder. Hence, BlackSwan's comment about using the proper Oracle-supplied utilities.

There is a document called "Oracle Database 2 Day DBA" . I think it is a great beginner document.

http://docs.oracle.com/database/121/nav/portal_booklist.htm

Check it out....look at http://docs.oracle.com/database/121/ADMQS/backrest.htm#i1004902 particularlly.

After looking through it let us know if you have specific questions or need more clarification.

Regards
Tim
