Issue Description
Why is the deduplication ratio lower in Oracle than in other applications?

Solution
Product and version information:

VTL3500 V100R002
VTL6000 V100R003C02
VTL6900 V100R005

Deduplication ratio depends on backup times and backup data type. The more times data is backed up for, the higher is the deduplication ratio. Oracle has less duplicate data, as a result, the deduplication ratio is lower.
