Snap EDR
A SnapExtension that copies the contents of a share from one SnapServer to another share
on one or more SnapServers. Snap EDR is designed to work with SnapServers and other
SnapServer Storage Solutions.
Snapback
The process of restoring a logical drive from a selected snapshot. This process takes place
internally in the RAID controller firmware and needs no support from any backup utility.
SnapDRImage
The SnapServer disaster recovery image that saves server-specific settings such as server
name, network, RAID, volume and share configuration, local user and group lists, and
snapshot schedules.
SnapExtension
A Java application that extends a SnapServer's functionality. SnapExtensions are produced
both by SnapServer and third-party vendors.
SnapServer Manager
The SnapServer Manager (SSM) is a Java-based utility for discovering and monitoring
SnapServers.
Snapshot
A method for producing a point-in-time image of a logical drive that results in a consistent,
stable, point-in-time image of a volume (filesystem) used for backup purposes. In the
process of initiating a snapshot, no data is actually copied from the snapshot logical drive.
However as new writes are made to a snapshot logical drive, existing data blocks are copied
to the ODA
Snapshot LUN
A special LUN created from a combination of the snapshot logical drives' data and the data
contained in the ODA.
Snapshot Number
Identifier that references one of several snapshots of the same logical drive.
Snapshot Pool
Disk space reserved within a RAID for the storage of snapshot data. In the default storage
configuration of many SnapServers, twenty percent of the RAID capacity is allocated to the
snapshot pool.
Snapshot Share
A virtual folder that allows access to all current snapshots at the same directory level as the
original share on which it is based.
SNMP
Short for Simple Network Management Protocol. A system to monitor and manage network
devices such as computers, routers, bridges, and hubs. SNMP views a network as a
collection of cooperating, communicating devices, consisting of managers and agents.
