Unitrends has three modes of deduplication.
- No Deduplication (Compression and Hashing Only)
- Post Process Deduplication (Compression First, Deduplication Later)
- Advanced Adaptive Deduplication (Deduplication on Arrival and Synthesis)
Unitrends recommends #3 as long as the hardware can handle it.
To set the deduplication level, select the settings icon in the top-right corner, click DEDUPLICATION SETTINGS and select Level 3 (Optimized for retention).
