Continuous Data ProteCtion with unlimiteD snaPshots
A data snapshot is simply a point-in-time image of your stored files. Snapshot technologies are useful for creating copies of
large data volumes without the need to actually move all the data or consume large amounts of space.
When data is generated by multi-tasking, multi-users, or within virtualized environments, it is changing at a rapid pace. In
these cases, traditional backup techniques always lag behind the actual data changes. This means that traditional backups
can’t suciently provide adequate protection as changes are happening and in many cases they can’t even meet the out-
dated 24-hour protection that was once considered standard practice.
To solve this problem, enterprise backup solutions perform backups using instant snapshots to create read-only copies the
data frozen at a point in time. This then allows applications to continue writing their data, while retaining a synthetic full
copy of data for safe keeping.
Snapshots have long been the data protection solution utilized by enterprise and government agencies. Large storage
vendors such as EMC, NetApp, and IBM have pioneered the big business adoption of snapshot technology. However, each
vendor has implemented the snapshot concept in slightly dierent ways. Of these, pointer-based snapshot techniques
have been most successful at providing protection of mission-critical data.
In 2012, NETGEAR® ReadyDATA™ brought enterprise-class pointer-based snapshot technology to small and medium
businesses at a price of less than $10k. In 2013, NETGEAR ReadyNAS® is bringing snapshot technology to everyone,
starting at just $200.
