When replication is enabled and configured, two copies of the data
exist, the original on the source system and a copy on the target system.
If the data on the source is destroyed or corrupted, the replicated copy
on the target system can be accessed through the Recover process or
through the Failback and Recover process (for more detailed
information on data recovery, see
page 185).
This section is divided into the following sections:
• Recovery Processes
• Recovery Requirements
• Recovery Features
The differences between these two data recovery processes are
explained in the following sections:
• Recover Process
• Failback and Recover Process
Recover Process
The Recover process is used when the source system where the original
data stored is unavailable or the original data is corrupted. The Recover
process takes the metadata on the target system and creates a copy of
this data in a new NAS share. This new NAS share will now be accessible
for use on the Target system.
