Smart Agents are loaded onto all protected servers – physical and virtual. Designed for
both physical and virtual environments, Smart Agents consume no more than 1%-2% of

Deduplication and
Compression
Integrated global deduplication and compression reduces the size of incremental
snapshots as they are ingested, greatly reducing backup storage requirements3

79. @Dell_Storage Evento Dell - Omega
How AppAssure works – Disaster Recovery
22
Backup images of both the protected data and the application stack are stored on the
Core. Deduped and compressed backup images can then be efficiently replicated to a
disaster recovery location – virtual, physical or the cloud.4
