bACkup to iSCSi
An iSCSI backup will create a complete copy of the logical drive,
including the RAID configuration. Data can be restored to a DataGuard
Appliance from an iSCSI backup without creating a new logical drive
and file system.
To recreate a logical drive and data, the DataGuard Appliance must
have the same number of unconfigured hard disks available as were
present when the iSCSI backup was created. The DataGuard Appliance
must also be configured as an iSCSI initiator for the device that it will
use for iSCSI Backup.
To configure the NAS as an iSCSI initiator, see “iSCSI Initiator” on page
78. To review the process used to restore a logical drive from the
iSCSI target, see “iSCSI Restore LD Process” on page 73.
To create an iSCSI Backup of a logical drive, follow these steps:
From the NAS tab, click the Backup menu item, then click the Backup
to iSCSI folder tab.
1. Click the Create button to open the Create iSCSI Backup menu.
2. Enter the IP address of an iSCSI device configured for use by the
DataGuard Appliance; it is also possible to change the port here.
Click the Next button.
3. The new menu lists the IP address and port you entered for
the iSCSI device. The iSCSI name (IQN) appears here. If CHAP
authentication is used, enable it by checking the CHAP option box,
then type the User Name and Password used for CHAP. Click the
Next button.
4. In the new menu, information entered previously is listed including
the IQN and CHAP status (ON or OFF). If multiple LUN are
mapped for use on the iSCSI devices, choose the one to use for
the configured backup. It is a good idea to enable a Snapshot to
be saved to the iSCSI, especially if a write activity will take while
the backup is in progress. Check the Snapshot box to enable a
Snapshot backup to iSCSI.
5. Select one of the schedule types you want for the backup solution.
6. When done, click the Run button to begin backing up immediately.
Click Save to save the schedule and account settings.
