Prerequisites
A replication peer configuration with a remote cluster where resides a snapshot that you want to clone.
Cloning a Remote Snapshot in VAST Web UI
From the left navigation menu, select Data Protection and then Global Snapshot Clones.
Click Create Global Snapshot Clone.
Complete the fields:
Name
Enter a name for the snapshot clone.
Background sync
Enabling this setting causes the snapshot data to be copied from the source to the destination after the clone is created. During the copying stage, read requests are directed to the source if the requested data is not yet copied. When the copying is complete, the clone becomes a local directory.
If this setting is disabled, the snapshot data is not copied to the destination except when there is a request to read data.
Target tenant
The tenant on the local cluster to which you want to clone the snapshot.
Target Path
The local path on the target tenant to create, where you want the clone to reside. An existing path is not valid.
Source cluster
Select a replication peer from which you want to clone a snapshot.
Source tenant
Select the tenant on the source cluster where the path that you want to clone resides.
Source path
After selecting the source cluster, select a path on the source cluster that you want to clone. The dropdown offers you a selection of paths that are protected by protected paths or by manual snapshots.
Source snapshot
After selecting the source path, select the specific snapshot to clone. The dropdown shows you all available snapshots for the selected source path.
Click Create.
The global snapshot clone is completed within a short time and becomes instantly available on the destination.
The clone is manageable as a Global Snapshot Clone from the Global Snapshot Clones tab, and you can do the following actions:
Pause and resume the clone (while it is in progress).
Stop the clone, while it is still in progress.
Remove the clone, when it is finished.
Cloning a Remote Snapshot in VAST CLI
Use replicationpeer list to list remote replication peers.
Use cluster list-tenants-remote to list tenants on a remote peer.
Use cluster list-clone-snapshoted-paths-remote to list paths with snapshots on the remote peer.
Use cluster list-snapshoted-paths-remote to list snapshots per path on remote peer.
Use the globalsnapshotclone create command to create a clone of a given snapshot.
