I assume that means forms has to be involved.
I ask because doing backups via forms is not normal, most companies just take nightly backups of the DB using the rman, run from a scheduler (db or cron).
There's no easy way to do it from forms as that's just not how it's done.
So are you absolutely sure that forms has to be involved or has your client just asked for this because they don't really understand what's involved in backing up a database?

You can take backup through push button or menu but you cant do it restore for some data merging and data corruption problem.
Taking a backup by press button or menu is below and understand it step by step.
1. First of all create a push button or menu (Name = Take Backup or any name u want)
2. Copy the below trigger code in push button or menu
begin
host('exp You_User_Name/Your_password@TNS_name file=D:\backups\backup_'||to_char(sysdate,'ddmmrr_hhmiss_am')||'.dmp');
----(D:\backup is file path where backup file saved after creating and to_char(sysdate,'ddmmrr_hhmiss_am' is a automatic creating file name with present sysdate and time.)
if form_success then
message('Backup Created successfully.')
message('Backup Created successfully.')
else
message('Some error Occurred while performing backup action');
end if;
end;

An export is just a logical backup, not a real backup. OP hasn't really said what they mean by backup. For example, table, schema or entire database.

You have several problems. The major one is that you don't know what you are doing. Another one is that you don't know how you'd do that. Then, you are assigned a task to do something you don't know with a tool that is probably the wrong choice. Smells like a BIG failure.
Maybe you should take step by step and focus on one problem at a time, think it over, read documentation, meet the enemy.
As your client told you to implement "backup" (did you ask them what they mean by saying that? What kind of a backup? Backup what exactly?) into your Forms application, I'm not sure they know what they are talking about or you didn't understand the requirement.
Is it to backup only some data from several tables (for example, INSERT them into another table and UPDATE the source table if something goes wrong)?
Is it a logical backup (export); you can use HOST built-in and run EXP (or EXPDP), but you most probably won't import that back easily because of existing objects, data stored within these objects, whether some of them have to be restored (or all of them), how will referential integrity constraints affect that process etc. Generally speaking, not a straightforward task.
Is it a RMAN backup? I know nothing about it, I'm not a DBA and I don't know what it involves. Lucky me, I don't have to implement it into a Forms application so I won't read any documentation at the moment, but you probably should.
So, go back to your client and do the first step. You and they must understand each other VERY well before you move on to the next step.

If they want to be able to completely restore data in the event of hardware failure etc then they definitely do not want inserts/updates. They want RMAN.
I strongly suggest you go and read the documentation on it and learn what it does.
Or go and hire a DBA who knows how to use it.

i have mentioned already in my post. Restore command is not comfortable from Button or Menu. because its merging or loss your data, So every Developer manage it manually. In addition when you restore data it required a File name (which one u want to restore) here is a main fault to manage restore automatically because you can not give any file name automatically when user pressed Restore Button. So that its main problem and not manageable.
