What is the difference between Snapshot and SnapMirror?
the diffrence between snapvault and snapmirror is almost the same both using snapshot technology, but snapmirror is replication from primary controller and secondary controller and snap mirror use the snap update to compare the snapshot between secondary and the primaryif there are any changes at the block then …
How does SnapMirror work in NetApp?
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 SnapMirror in NetApp cluster mode?
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 can provide users immediate access to mirrored data in case the source goes down.
What is SnapManager in NetApp?
NetApp® SnapManager® automates and simplifies the complex and time-consuming processes associated with the backup, recovery and cloning of databases. SnapManager uses NetApp ONTAP® SnapMirror technology to create copies of backups on another volume and ONTAP SnapVault® technology to archive backups to disk.
What is SnapVault volume?
A SnapVault backup is a collection of Snapshot copies on a FlexVol volume that you can restore data from if the primary data is not usable. A volume to which data is backed up from a primary volume. Such a volume can be a secondary or tertiary (and onward) destination in a cascade or fanout backup configuration.
What is NetApp Snapshot?
A Snapshot copy is a point-in-time file system image. A NetApp Snapshot copy simply manipulates block pointers, creating a “frozen” read-only view of a WAFL volume that lets applications access older versions of files, directory hierarchies, and/or LUNs (logical unit numbers) without special programming.
What is a FlexClone?
A FlexClone volume is a fully functional FlexVol volume similar to its parent. A FlexClone volume is always created in the same aggregate as its parent. A FlexClone volume is always created in the same Storage Virtual Machine (SVM) as its parent. An Infinite Volume cannot be used as the parent of a FlexClone volume.
What port does SnapMirror use?
port 10566
SnapMirror source binds on port 10566.
What is FlexCache in NetApp?
FlexCache is a remote caching capability that simplifies file distribution, reduces WAN latency, and lowers WAN bandwidth costs. It enables distributed product development across multiple sites, as well as branch office access to corporate datasets.
What is SnapMirror resync in NetApp?
The snapmirror resync command enables you to reestablish a broken SnapMirror relationship without a lengthy baseline transfer. Resynchronization of FlexVol volumes. If there are any changes on the destination system that you need to replicate to the source, you can use qtree SnapMirror to resynchronize data.
What is SnapDrive in NetApp?
SnapDrive helps you automate storage provisioning tasks and manage data in SAN and SMB 3.0 Windows environments. You can run SnapDrive software on Windows hosts in either a physical or a virtual environment. It enables online storage configuration, LUN expansion, and streamlined management.
What is the difference between 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…
How does SnapVault take a snapshot of the data?
SnapVault will create a full copy of the source data at the secondary site and take a Snapshot upon completion. According to a schedule set by the operator, SnapVault will create incremental Snapshots of the primary site’s data at the secondary site.
Why does SnapMirror store only snapshot copies of data?
SnapMirror stores only the Snapshot copies that reside in primary storage, because, in the event of a disaster, you must be able to fail over to the most recent version of primary data you know to be good. Your organization, for example, might mirror hourly copies…
What do you need to know about SnapMirror?
With SnapMirror, the user establishes a pairing between a read-write accessible production volume at the primary site and a read-only mirror volume from a secondary site. A SnapMirror pair can operate in one of three modes: Synchronous, Semi-Synchronous, or Asyncronous.
