Deleting a Replication Source
Delete a system from the list of replication sources if it will no longer send replicated data
to the ETERNUS CS800. After the source system is deleted, the ETERNUS CS800 will no
longer accept replicated data from that system.
To delete a replication source:
1. Under Source System, select one or more sources to delete.
2. Click Delete.
If a source ETERNUS CS800 is deleted from the list, its contribution to the
cumulative totals on the Home page are not removed until you clear Receive
statistics (see
Changing the Maximum Number of Snapshots
During scheduled or manual data replication, the ETERNUS CS800 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 ETERNUS CS800 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:
Under Source System, in the Maximum Snapshots drop-down box, select the number
l
of snapshots to retain for each replicated share or partition.
The default value is 10. The maximum value is 32.
l
Retaining more than the default number of snapshots will use additional disk
space on the target ETERNUS CS800. This can cause the target ETERNUS CS800 to
fill up more quickly.

10.6 PTT Configuration

The PTT page allows you to configure the path to tape (PTT) feature of the ETERNUS CS800.
There are two types of path to tape:
Backup application specific path to tape allows you to move data from the ETERNUS
l
CS800 to physical tape cartridges in an attached physical tape library using an NDMP
(Network Data Management Protocol) connection. The ETERNUS CS800 supports NDMP
V4.
OST path to tape (also called Direct To Tape) allows you to use Symantec NetBackup to
l
copy LSUs from a storage server on the ETERNUS CS800 to a physical tape library.
