What is a SnapMirror?
SnapMirror is a feature of Data ONTAP that enables you to replicate data. SnapMirror enables you to copy data from specified source volumes or qtrees to specified destination volumes or qtrees, respectively. You need a separate license to use SnapMirror.
How do you get a SnapMirror relationship?
- Verify the cluster peer relationship and SVM peer relationship.
- Create the SnapMirror relationship (Beginning with ONTAP 9.3)
- Create the SnapMirror relationship (ONTAP 9.2 or earlier)
- Set up the destination SVM for data access.
- Monitor the status of SnapMirror data transfers.
What is the difference between SnapVault and SnapMirror?
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.
How does SnapMirror work 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 update?
The snapmirror update command updates the destination volume or non-Data ONTAP endpoint of a SnapMirror relationship. The snapmirror update command behaves differently for data protection (DP), extended data protection (XDP) and load-sharing (LS) relationships.
How does SnapVault work in NetApp?
SnapVault Snapshot copies capture the state of primary qtree data on each primary system. This data is transferred to secondary qtrees on the SnapVault secondary system. The secondary system creates and maintains versions of Snapshot copies of the combined data for long-term storage and possible restore operations.
How do I create a SnapMirror schedule?
Steps
- From the SnapMirror tab or SnapVault tab of the Configure Protection dialog box, click the Create Schedule link in the Relationship Settings area. The Create Schedule dialog box is displayed.
- In the Schedule Name field, type the name you want to give to the schedule.
- Select one of the following:
- Click Create.
How do I change my SnapMirror schedule?
Change the schedule for a mirror relationship by using the snapmirror modify -schedule command. This command must be used from the destination SVM.
What is XDP SnapMirror?
Starting with ONTAP 9.5, SnapMirror extended data protection (XDP) mode replaces SnapMirror data protection (DP) mode as the SnapMirror default.
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.
How do I update Snapmirror on Netapp?
Use the snapmirror update-ls-set command to update a set of load-sharing mirrors. For extended data protection (XDP) relationships with a snapmirror policy of type async-mirror , a snapmirror update always creates a new Snapshot copy on the source volume.
