Instant Recovery Using Hp Storageworks Eva Smis-S Agent - HP Data Protector A.06.11 Integration Manual

• By selecting the Restore using Microsoft Virtual Disk Service option, you can
restore your data without using HP StorageWorks EVA SMIS-S Agent or HP
StorageWorks XP Agent.
Disadvantages
• It is not possible to perform another instant recovery using the same replica.
• This method of instant recovery changes the physical location of the application
data, since, after instant recovery, a replica becomes the source volume. The
application starts running on the physical disks that were used for backup. If the
selected replica and its source volume belong to separate disk groups, the two
disk groups are also switched during instant recovery.
To use this method of instant recovery, in the Data Protector GUI, select the Restore
using Microsoft Virtual Disk Service option.

Instant recovery using HP StorageWorks EVA SMIS-S Agent

Depending on the instant recovery options you select in the Data Protector GUI,
instant recovery can be performed in three different ways.
Switch of disks
For description on this method, see
To use this method of instant recovery, in the Data Protector GUI, select the Restore
using HP StorageWorks EVA and Switch to the replica options.
Copy of replica data with the source volume retained
With this method, a new copy from a replica is created in the same disk group in
which the source volumes reside. When the copy is finished, a switch of disks between
the source and the new copy is performed. The old source volumes are retained.
If the restore session fails or is aborted, the VSS integration reverts the application
and backup environment back to the state in which they were before the instant
recovery.
You can also select to retain the replica and thus enable to perform another restore
from this backup.
Advantages
• The original source volumes are retained after restore.
