Export/Import: traditional backup of oracle database, we can't resume the export/import job if we stop the job in middle. We can't attach any job to running job @ exp/imp. We need not to create a file structure @ oracle level

Datapump: It's introduced from 10g. We can resume the datapump job if we stop the job in middle. We can attach a datapump job to running job. We need create file structure @ oracle level and OS level.

Answer / kranthi shiva

Datapump--it is having byte
it is having parallelism concept
Incremental backups
we can restart the job, kill and resume the job.
Export/Import-- here we cannot resume the job
it is having bit level or block level
it is not having incremental backup
