9.1.2. Snapshots
To facilitate backup and recovery operations, you can schedule and create
snapshots of iSCSI virtual disks. A snapshot is a point-in-time, read-only
copy of an iSCSI virtual disk. Snapshots are typically used as interim copies
of data that has been modified since the most recent backup. Snapshots
offer the following advantages:
• Snapshots can be scheduled to be created automatically.
• Snapshots are space-efficient because they are differential copies.
• It is not necessary to close files or stop programs when creating
snapshots, so application servers
• can continue servicing clients without disruption.
• Each snapshot is typically created in less than one minute—
regardless of the amount of data.
• Snapshots are useful for fast system recovery of files and volumes,
in case of accidental data
• deletion by a user, overwritten data, or data corruption resulting from
a malicious program.
• Snapshots can be mounted locally or exported to facilitate backup
and recovery operations.
9.1.3. Wizards
To support creation and management of iSCSI targets, virtual disks, and
snapshots, the iSCSI Software Target snap-in provides several wizards.
9.1.4. Create iSCSI Target Wizard
This section describes how to create an iSCSI Target using the Create iSCSI
Target Wizard.
1. Log on to the storage server using an account with administrative
privileges.
2. Open the Microsoft iSCSI Software Target MMC snap-in by clicking
Start > Programs > Administrative Tools > Microsoft iSCSI
Software Target.
3. Click the iSCSI Targets node. On the details view (right pane), right-
click and select Create iSCSI Target.
4. Click Next on the Welcome page of the wizard.
5. On the iSCSI Target Identification page, type a name and
description for the iSCSI Target and then click Next.
6. On the iSCSI Initiators Identifiers page, type the iSCSI Qualified
Name (IQN) of the iSCSI initiator requesting access to the iSCSI
Target in the IQN identifier field. The IQN is found on the General
tab of the Microsoft iSCSI Initiator interface.
