What is SnapMirror and SnapVault?
SnapMirror is disaster recovery technology, designed for failover from primary storage to secondary storage at a geographically remote site. SnapVault is archiving technology, designed for disk-to-disk Snapshot copy replication for standards compliance and other governance-related purposes.
What is SnapMirror replication?
SnapMirror is a feature of Data ONTAP that enables you to replicate data. SnapMirror enables you to replicate data from specified source volumes or qtrees to specified destination volumes or qtrees, respectively. You need a separate license to use SnapMirror.
Does SnapMirror use NDMP?
At the start of a SnapMirror to Tape copy operation, the file server generates a snapshot of the file system. NetApp provides an NDMP environment variable to control whether this snapshot is removed at the end of the SnapMirror to Tape operation.
What is Snapshot and SnapMirror?
SnapMirror replicates data from a source volume or qtree to a partner destination volume or qtree, respectively, by using Snapshot copies. Before using SnapMirror to copy data, you need to establish a relationship between the source and the destination.
What is a SnapVault?
SnapVault is a disk-based storage backup feature of Data ONTAP. SnapVault enables data stored on multiple storage systems to be backed up to a central, secondary storage system quickly and efficiently as read-only Snapshot copies.
What is SnapVault in NetApp?
with NetApp SnapVault SnapVault helps you respond with replication-based disk-to-disk backup. With SnapVault, your backups finish in minutes instead of hours or days. You can keep weeks, months, or years of backups online, all while your disk capacity requirements are reduced up to 90% in virtualized environments.
What is DP and XDP in NetApp?
“DP” are block-based and uses BRE (Block Replication Engine) “All the rest of it”, (file-based) i.e XDP, SnapVault and version independent SnapMirror uses LRE (Logical Replication Engine) BRE (suited for disaster type of scenario) = Tracks each “block” and is unaware of file-system structure.
What protocol does SnapMirror use?
Supported features. In ONTAP 9.5 and later, SnapMirror Synchronous technology supports the NFSv3, FC, and iSCSI protocols over all networks for which the latency does not exceed 10ms.
What is FlexClone in NetApp?
FlexClone technology creates exact, virtual copies of data volumes, files, and LUNs without additional storage space. NetApp® FlexClone® technology instantly replicates data volumes and datasets as transparent, virtual copies—true clones—without compromising performance or demanding additional storage space.
How do you set up SnapVault?
To configure a SnapVault secondary storage system, you need to log in to the secondary system’s console and enable the SnapVault license. You can configure a schedule for Snapshot copies on both the primary and the SnapVault secondary storage systems. You can set the schedules to an hourly, weekly, or nightly basis.
