EMC SnapView
EMC® SnapView™ software helps make applications and data accessible when and where you need them by
creating mountable snapshots or full-copy clones of production data on your CLARiiON® array. The process is
transparent to the primary server, and the resulting data copy is available to any secondary server with
appropriate access privilege. EMC SnapView software is designed to:
• Improve data recovery and application consistency
• Minimize recovery time by creating frequent point-in-time images
• Integrate with Microsoft® Exchange®, SQL Server™, and Oracle® environments
• Be easily managed with EMC Navisphere® Management Suite
Better backups: It's all about information access
In the global economy, information must be accessible all the time. If your data is unavailable, it’s not working
for you, processing transactions and serving your customers, that’s money lost. SnapView software can help
you back up faster and more flexibly, so you can be up and serving customers for more hours of the day. Reduce
backup windows to just seconds using snapshot copies and keep applications online and productive. You can
also backup more frequently for daily disaster protection.

Faster application development, reliable testing and more
EMC® SnapView™ lets you create multiple copies of production data. The same local copy of data that can be
presented to a backup utility for processing can also be presented, readable and writable, to development hosts
for rapid application development and testing. SnapView can help you reduce development time and enhance
reliability by testing applications with current data. With multiple data copies, you can run testing, decision
support, debugging or routine maintenance in parallel.
How SnapView works
SnapView lets system administrators create, in background mode, a mountable snapshot or full-copy clone/BCV
of production data. The process, handled on the Dell/EMC array, is transparent to the primary server, yet the
resulting data is available to any secondary server with the appropriate access privileges.
When you start a SnapView snapshot session, the snapshot becomes active and I/O to the source LUN
continues. When the production server issues a write to any data in the source LUN being snapped, SnapView
implements a copy-on-first-write algorithm to copy the original block into a private area on the array before
modifying the original data. This private area is called the SnapView Save Area. For any changed block, the copy
happens only once, the first time the block is modified.
A snapshot is composed of all the unchanged blocks in the source LUN, plus the blocks that have been written
into the SnapView Save Area. The SnapView Save Area contains only the original data blocks written to it when
those blocks were about to be changed in the source LUN. Thus, the storage capacity required to implement
SnapView is merely a fraction of the size of the source LUN.
The snapshot process allows I/O to continue to the production file system with no disruption in service, while
other applications and servers have complete access to the snapshot of the data, if permissions allow. The
resulting snapshot is fully readable and writable by a secondary server. SnapView also supports a feature called
snapshot rollback. Snapshot rollback enables you to restore snapshots directly to production volumes.

Alternatively, you can use SnapView™ to create a full-image copy of your volume and present it to a secondary
server as a unique LUN. This full-image copy is called a business continuance volume (BCV) or clone. SnapView
can track all changed blocks and incrementally re-establish the BCV—copying only changed tracks to the
BCV—to bring it back into sync with the original. You can also incrementally restore the image from the BCV
back to the original volume.
Clones/BCVs differ from snapshots in that they are physically separate copies of your data—no portion is
shared between the original and the clone/BCV volumes. Physical or logical loss of data on the original will not
affect the data contained in the clone/BCV, or vice versa.
SnapView can manage up to eight clones/BCVs and eight snapshot copies of a volume. In addition, SnapView
allows you to have up to eight snapshots of each clone/BCV you’ve made. This greatly expands the number of
data replicas you can generate and use—for backups, application development, testing, decision support—
whatever you need the data for.
