Answer 1

To back up database in archive mode is just keeping the tablepsaces in backup mode & copy the tablespaces in operating system level.
Usually in production environment we use backup utility by name Netbackup or BackupExec from Veritas (veritas.com),where we backup all the directories of datafiles which comprises the database.
If you do not have any of these tools you need to write scripts to take the backup manually.
see the sample shell script i wrote to take the backup of database.This script is for cold backu ( noarchive log mode).You can cusomise ths script according to your environment & can be used for Hot backup.
