You can use System Manager to create and manage vault relationships by using the vault policy.
Creating a vault relationship from a destination SVM
You can use System Manager to create a vault relationship from the destination storage virtual machine (SVM), and to assign a vault policy to create a backup vault. In the event of data loss or corruption on a system, backed-up data can be restored from the backup vault destination.
Deleting vault relationships
You can use System Manager to end a vault relationship between a source and destination volume, and release the Snapshot copies from the source.
Editing vault relationships
You can use System Manager to edit a vault relationship either by selecting an existing policy or schedule in the cluster, or by creating a new policy or schedule. However, you cannot edit the parameters of an existing policy or schedule.
Initializing a vault relationship
You can use System Manager to initialize a vault relationship if you have not already initialized it while creating the relationship. A baseline transfer of data is initiated from the source FlexVol volume to the destination FlexVol volume.
Updating a vault relationship
You can use System Manager to manually initiate an unscheduled incremental update. You might require a manual update to prevent data loss due to an upcoming power outage, scheduled maintenance, or data migration.
Quiescing a vault relationship
You can use System Manager to disable data transfers to the destination FlexVol volume by quiescing the vault relationship.
Resuming a vault relationship
You can resume a quiesced vault relationship by using System Manager. When you resume the relationship, normal data transfer to the destination FlexVol volume is resumed and all vault activities are restarted.
Restoring a volume in a vault relationship
You can use System Manager to restore Snapshot copies to a source or other volumes if the source data is corrupted and is no longer usable. You can replace the original data with the Snapshot copies in the destination volume.
What a SnapVault backup is
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. Snapshot copies are created based on a Snapshot policy. The SnapVault backup backs up Snapshot copies based on its schedule and SnapVault policy rules.
How a SnapVault backup works
Backing up volumes to a SnapVault backup involves starting the baseline transfers, making scheduled incremental transfers, and restoring data upon request.
How SnapVault backups work with data compression
SnapVault relationships preserve storage efficiency when replicating data from the source to the SnapVault secondary volume except when additional data compression is enabled.
SnapVault backup limitations
When planning SnapVault relationships, you must keep in mind what is supported and what is not supported.
Data protection for SVM namespace and root information
Backups to secondary volumes in SnapVault relationships between FlexVol volumes replicate only volume data, not the storage virtual machine (SVM) namespace or root information.
