backup set

A SnapManager backup set, often referred to as a backup set, is the complete set of data required to form a restorable backup or archive: all Exchange data Snapshot copies, all transaction log Snapshot copies, and the SnapInfo directory.

Exchange

In this guide, the term Exchange is used to describe Microsoft Exchange 2000 or Microsoft Exchange 2003. Information about a particular version of Exchange will be labeled with the Exchange version number or numbers.

Exchange environment

The Exchange organization and the supporting Windows server environment.

Exchange organization

The entire Exchange deployment (all of the Exchange servers).

file system

The native Windows file system supported by SnapManager using NTFS.

LUN (Logical Unit Number)

A logical unit of storage that can be managed by SnapDrive in a SAN environment. Within the Windows operating system, LUNs appear as locally attached disks. The terms "LUN" and "virtual disk" are synonymous; this document uses the term "LUN".

SFSR

Single File Snap Restore. An SFSR reverts a single file to the version of that file contained in a particular Snapshot copy. After a file has been restored using SFSR, all user-visible information (data and file attributes) for that file in the active file system are identical to the state contained in the Snapshot copy. SnapManager uses SFSR to restore a LUN to its state when a SnapManager backup was taken.

Snapshot copy

An online, read-only copy of a volume. For more information about Snapshot copies, see SnapManager and Snapshot copies.

storage group

This Microsoft concept refers to a group of one to five databases (information stores) and an associated set of transaction log files, all of which are mounted on the same Exchange server.

storage group set

One or more Exchange storage groups that belong to the same Exchange server and are stored on the same storage system volume.

Storage groups in the same storage group set are displayed in the same color and are all automatically preselected when one is selected to be backed up.

storage system

Any NetAppstorage product that supports FCP (Fibre Channel Protocol) and iSCSI (SCSI over IP).

This guide refers to all NetApp storage products (filers, IBM N series storage systems, and NearStore systems) as storage systems. In other documentation, the terms filer and appliance have also been used to refer to storage systems.

virtual disk (LUN)

A logical unit of storage that can be managed by SnapDrive in a SAN environment. Within the Windows operating system, LUNs appear as locally attached disks.

volume

A logical unit of data storage on a storage system.

Windows Server environment

A group of Windows servers providing basic services such as Active Directory, DNS, DHCP, and so on. Sometimes also referred to as a Windows environment.
