Deleting a Replication Source
Delete a system from the list of replication sources if it will no longer
send replicated data to the DXi4000. After the source system is deleted,
the DXi4000 will no longer accept replicated data from that system.
To delete a replication source:
1 Select the system in the Source DXis list.
2 Click Delete .
Note: If a source DXi is deleted from the list, its contribution to the
cumulative totals on the Home page are not removed until you
clear Receive statistics (see Replication Performance on
page 111).
Maximum Received Snapshots
During scheduled or manual data replication, the DXi4000 receives a
snapshot from the source system. A snapshot contains all of the data
necessary to fully recover or failback a NAS share to the point in time
when the snapshot was saved.
The DXi4000 can retain up to 24 snapshots for each replicated share.
Once the maximum number of snapshots have been saved, the oldest
snapshot is deleted to make room for each new snapshot that is
received.
To configure the maximum number of received snapshots:
1 In the Maximum Snapshots Per Share drop-down box, select the
number of snapshots to retain for each replicated share.
The default value is 10. The maximum value is 24.
