SnapServer Snapshot Highlights: |

Snapshot technology from Overland Storage enables IT administrators to take instant, disk-based point-in-time images of any SnapServer storage volume on the network. SnapServer solutions support snapshots of iSCSI volumes and the included VSS provider ensures application consistency on a Windows platform. Utilizing snapshots with VSS compliant backup applications increases backup efficiencies and reduce backup windows. IT administrators can take immediate or scheduled images of a file system without disrupting users. Countless recovery points ensure recovery point and recovery time objectives are met Unlike conventional snapshots, which typically allow a maximum of a few hundred recovery points, SnapServer replicas are designed to handle up to hundreds of thousands of recovery points ensuring that businesses can maintain data access even in the event of a disaster. |
Customer Needs Snapshots provide automated virtual point-in-time backup data with minimal storage usage. Benefits Reduces administrative intervention required to restore individual end user files Increases application availability Reduces space usage required for backups |
Momentarily pauses live volume activity to capture the most complete snapshot, while maintaining read/write access Can accommodate multiple concurrent snapshots Read-only access allows users to recover files without modifying the snapshot Reduces costs while enhancing data availability Integrated into GuardianOS and SnapServer Manager |
Included with Snap Server NAS 650, 620 and 520; optional for Snap Server NAS 410, 210, and 110. |
Instant virtual volume - The snapshot instantly captures a copy of the live volume. Point-in-time image - The snapshot is a virtual image of the live volume as it appeared at the point-in-time when the snapshot was captured. It creates a nearly instant map of pointers to the actual blocks of data found in the live volume. Disk-based storage - The snapshot images are stored entirely on disk. Blocks of data that have not changed since the completion of the snapshot remain in the live volume, while the original contents of data blocks that have changed are stored in designated "snapshot" spaces. Sustained client access to the live volume - With the exception of a momentary pause as the live volume is frozen and captured in the snapshot image, network clients maintain read/write access. Read-only access to the snapshot volume - Users have read-only access to the individual snapshot volumes. Since these snapshot images are true point-in-time copies of live volumes, users cannot manually modify them, protecting the snapshot from inadvertent user error. Performance maintained during concurrent snapshots - The GuardianOS server can accommodate multiple concurrent snapshots per unit while continuing to maintain optimal performance. |
