WHAT WE TESTED
Compellent
Storage Center with Data Instant Replay, Server
Instant Replay, and Remote Instant Replay
SAN software certified for ESX Server

Replays utilize far less storage space
than snapshots by preserving only pointers to blocks that have changed

Thin Replication Improves both RPO and
RTO in Disaster Recovery:
