Integrated Snapshots and Replication
Robust business continuity made simple and efficient
TrueNAS offers a simple-to-use, automated file version retention and restoration system that provides unlimited and instant snapshots without intervention by administrators. With a comprehensive snapshot schedule, data is automatically protected locally against unintentional alteration and replicated remotely to another TrueNAS storage array for redundancy and/or disaster recovery.
TrueNAS does not require that you dedicate a portion of your usable space for snapshot or clone data -- the entire pool can be used as a space for snapshots and clones. Operations occur instantaneously, and the initial snapshot or clone uses no space. It is only when that data changes that space is used for the original or changed data. This makes snapshots and clones incredibly space-efficient. When you combine VM provisioning with storage optimization, TrueNAS ensures that VMs occupy minimal space, increasing IOPS and reducing latency.
In order to create a highly available fault-tolerant solution for backups or disaster-recovery, snapshots can be automatically replicated to another TrueNAS, either locally or remotely, making TrueNAS replication a core component in your physical or virtual server disaster-recovery plan. The replication schedule is completely configurable so the filesystem changes can move across the network or Internet at convenient intervals. Since TrueNAS snapshot replication only sends across the new or changed data, network traffic is kept to a minimum.
