protection.

snapshot
A snapshot is a common industry term that defines the ability to capture and store the state of a disk volume at a
given point, while applications are running. The snapshot is critical if system recovery is needed due to an outage
or system failure. Rapid Recovery snapshots are application aware, which means that all open transactions and
rolling transaction logs are completed and caches are flushed prior to creating the snapshot. Rapid Recovery
uses Microsoft Volume Shadow Services (VSS) to facilitate application crash consistent snapshots.

database. Differential backups are typically faster to create than full database backups, and reduce the number of
transaction logs required to recover the database.

Transport Layer Security
Transport Layer Security (TLS) is a modern cryptographic network protocol designed to ensure communication
security over the Internet. This protocol, defined by the Internet Engineering Task Force, is the successor to
Secure Sockets Layer (SSL). The SSL term is still generally used, and the protocols are interoperable (a TLS
client can downgrade to communicate to an SSL server).
