Hi,

Backup and Recovery is Very important part of database.
it will depand on Database.

Two types of backup method.
1.RMAN ( server managed )
2.User Managed

-----------------------------------
Two types of backup
1.Cold Backup

If your able to shutdown database complete ( downtime) then you can take complete database backup with all database files , password files, server parameter files.

In Cold backup your not able to perform point in time recovery.
----------------------------------------------------------
2.Hotbackup

If you have no downtime ( your not able to shutdown your database) database running 24x7 then you have to choose hotbackup method.

-----------------------------------
Database running in two mode.
1.Archive log
In archive log mode your able to perform point in time recovery through .arc files.

2.No Archive log mode.
Point in time recovery not possible.
---------------------------------------------------------

You have to start reading the documentation.
Get a complete picture, test and learn and then do it in real time.
If you cannot differentiate between hot/cold backup you are not supposed to it. THis is just a forum. We can help with specific issues but cannot teach you.

Alter tablespace users begin backup
copy datafiles
Alter tablespace users end backup
You cann't take hot backup because your database running in NO ARCHIVE LOG MODE.

you have to take cold backup.
see my previous post example in cold backup through USER MANAGED METHED.
