Recovering a Datastore From a Storage Center Snapshot
Use the Storage Center Snapshot Recovery wizard to recover data from a Storage Center snapshot. The wizard allows you to
select the snapshot from which you want to recover data and then exposes and maps the snapshot to allow you to copy data
for recovery.
Prerequisites
A snapshot of the datastore must exist.
Steps
1. Select the datastore for which you want to recover data.
2. Select Actions > All Dell Storage Actions > Snapshot > Recover Datastore from Snapshot.
The Storage Center Snapshot Recovery wizard starts.
3. Select a snapshot from which to recover data.
NOTE: Only one snapshot per volume can be selected.
4. Click Next.
The Host Selection page opens.
5. Select the host for accessing the recovered datastore.
6. Click Next.
The Datastore Name page opens.
7. Specify a name and location for the recovered datastore.
8. Click Next.
The Mapping LUN page opens.
9. Select the LUN for mapping the recovered datastore.
10. Click Next.
The Ready to Complete page opens.

Create and Manage Replications and Live Volumes
Use the plugin to add and manage replications and Live Volumes to VMFS datastores on Dell storage. You can use the plugin
convert a replication to a Live Volume and vice versa.
The Dell Storage vSphere Client Plugin supports two basic models for migrating data between Storage Centers:
● Replications
● Live Volumes
A replication copies volume data from one Storage Center to another Storage Center to safeguard data. A Live Volume is a
replicating volume that can be mapped and active on a source and destination Storage Center at the same time.
Replications can be synchronous or asynchronous:
● Asynchronous replication—Copies snapshots from the source volume to the destination volume. If the local Storage Center
or site fails before the write is delivered, it is possible that writes will not be delivered to the destination volume
● Synchronous replications—Keeps the source and destination volume fully synchronized at all times by making sure that each
write is successfully written to both the source volume and the destination volume before responding to the server.
Synchronous replications can be further defined by the mode:
● High Availability Mode—Accepts IO requests to the source volume when the destination volume is unavailable (or when
latency is too high) to avoid interrupting service. However, if writes are accepted to the source volume, the destination
volume data becomes stale.
