Failback and Recover Process
The
Failback
and
Recover
process is used when the source system has
been replaced or the original data on the source system has been
corrupted or destroyed. This process takes the data from the target
system and copies it back to the source system. This data once copied to
the source system must be recovered before it can be accessible.
Recovery Requirements
The following items are required for recovering data:
• CIFS NAS shares can only be recovered to identical CIFS shares.
• NFS NAS shares can only be recovered to identical NFS shares.
Recovery Features
Up to 24 replicated versions of a NAS share can exist on the target
system.
• The 24 versions represent the 24 most recent replications.
• You can selectively delete versions to keep some longer than the
default 24 replications.
• You can failback and recover any one of those 24 versions.
Note:
Replication of VTL partitions to DXi4500 is not supported.
Network Segmentation
Network segmentation provides the ability to split your network into
subnetworks or segments. There are two main purposes for segmenting
your network:
•
Separate Physical Interfaces
: if your network is physically
partitioned with no connectivity between the partitions, the
DXi4500 needs the ability to communicate with each partition
individually.
