Deleting a Replication Source
Delete a system from the list of replication sources if it will no longer send replicated data to the DXi4700.
After the source system is deleted, the DXi4700 will no longer accept replicated data from that system.
To delete a replication source:
1. Under
Source DXis
, select one or more sources to delete.
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
Replication Performance on page 160
).
Changing the Maximum Number of Snapshots
During scheduled or manual data replication, the DXi4700 receives a snapshot from the source system. A
snapshot contains all of the data necessary to fully recover or failback a NAS share or VTL partition to the
point in time when the snapshot was saved.
The DXi4700 can retain up to 32 snapshots for each replicated share or partition. 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 change the maximum number of received snapshots:
l
Under
Source DXis
, in the
Maximum Snapshots
drop-down box, select the number of snapshots to
retain for each replicated share or partition.
l
The default value is 10. The maximum value is 32.
Note:
Retaining more than the default number of snapshots will use additional disk space on the target
DXi. This can cause the target DXi to fill up more quickly.
PTT Configuration
The
PTT
page allows you to configure the path to tape (PTT) feature of the DXi4700. There are two types of
path to tape:
l
Backup application specific path to tape allows you to move data from the DXi to physical tape cartridges
in an attached physical tape library using an NDMP (Network Data Management Protocol) connection.
The DXi supports NDMP V4.
l
OST path to tape (also called Direct To Tape) allows you to use Veritas NetBackup to copy LSUs from a
storage server on the DXi to a physical tape library.
