Help!! Error during backup

Question

Hello, can anyone point me to the right direction...I was trying to backup my database because I know that there is something wrong with my Oracle 10g Express and I need to reinstall it.
During the backup process this is whats happening:
Warning: Log archiving (ARCHIVELOG mode) is currently disabled. If
you restore the database from this backup, any transactions that take
place between this backup and the next backup will be lost. It is
recommended that you enable ARCHIVELOG mode before proceeding so
that all transactions can be recovered upon restore. See the section
'Enabling ARCHIVELOG Mode...' in the online help for instructions.
Backup with log archiving disabled will shut down and restart the
database. Are you sure [Y/N]? y
Backup in progress...

Bawasi,

You should make a backup before something went wrong... What's wrong with your database?
