An iSCSI initiator application lets you set up a connection from a server to a LUN group (and therefore to individual LUNs). Normally, users would not initiate such a LUN connection; the network administrator would provide access to a LUN group through a server.
The iSCSI targets (that is, the LUNs in the LUN group on the ReadyDATA) present themselves on the client system as virtual block devices and can be treated as locally attached disks. Windows, for instance, can run FAT32 or NTFS on the iSCSI target device, and treat the devices as though they are locally attached.
When they have access to a LUN group, users can employ any backup application to back up local data from their iSCSI-attached device to a LUN.
Note: Unlike snapshots that reside on a share, snapshots that reside on a LUN are not visible to users. For information about how to recover data using a snapshot on a LUN, see the How do I recover data from a snapshot on my ReadyDATA storage system to an iSCSI-attached device? support article.
