what is Incremental Backup and how do we do it, not using RMAN, general backup script.
If the database is not in archivelog mode, can we do incremental backup.
Thanks
Toshi

It is not possible.
Even if it would be possible, since the database is in noarchivelog mode, it would make absolutely NO sense.

>> what is Incremental Backup
A backup of whatever changed , after the last backup.
RMAN does it in the lowest granularity. Blocks.
quoting documentation

An incremental backup reads the entire file and then backs up only those data blocks that have changed since a previous backup. You can use RMAN to create incremental backups of datafiles, tablespaces, or the whole database. Note that RMAN can include a control file in an incremental backup set, but the control file is always included in its entirety--no blocks are skipped.
