Managing Replication Sources
Replication sources send replicated data to the Q-Cloud Protect appliance.
You can perform the following tasks to manage the cloud appliance's allowed replication sources:
- From the Configuration, menu select Replication to display the Replication Target and Source Systems page.
- Review the following information in the Source Systems list:
The IP address of the source system that is allowed to send data to the cloud appliance.
Actual Data Received
The amount of data actually received over the network during replication.
Average Receive Rate
The average receive rate in MB/s of data received over the network during replication.
actual size of data sent over the network amount of time required to complete replication
Note: The statistics in the Source Systems list are for each source, rather than a cumulative total for all sources as is displayed on the Home page.
Additional Navigation Tips
You can customize the appearance of the Source Systems list in the following ways:
- To collapse or expand the list, click the top banner row of the list.
- To sort the rows in the table by column, click the arrow to the right of a column heading and select Sort Ascending or Sort Descending.
- To show or hide a column, click the arrow to the right of a column heading, and then click Columns. Select the check box to show a column, or clear the check box to hide a column.
Add a system to the list of replication sources to allow it to send replicated data to the cloud appliance.
You must add a source system to the list of allowed replication sources on the cloud appliance before you configure the source system to send replicated data to the target. The cloud appliance can receive replicated data from 1 source system.
- For more information about working with received snapshots, see Manage Incoming Replication Activities for NAS Shares or Manage Incoming Replication Activities for VTL Partitions.
- It is typical for the target system to require additional storage space for replicated data initially because it does not delete out-of-date data until replication is complete. For optimal performance, we recommend keeping the amount of free storage space on the cloud appliance at 20% or more. See Reviewing Storage Statistics.
Add a replication source
- From the Source System list, select the source system to delete.
- Click Delete.
Note: When a source system is deleted from the list, its contribution to the cumulative totals on the Home page are not removed until you clear Receive statistics. See Controlling Replication Traffic and Statistics.
During scheduled or manual data replication, the cloud appliance receives a snapshot from the source system. A snapshot contains all data necessary to fully recover or failback a NAS share or VTL partition to the point in time when the snapshot was saved.
The cloud appliance can retain up to 32 snapshots for each replicated share or partition. When the maximum number of snapshots have been saved, the oldest snapshot is deleted to make room for each new snapshot that is received.
From the Source Systems list, select the number of snapshots to retain for each replication share or partition in the Maximum Snapshots drop-down list.
The default value is 10. The maximum value is 32.
Note: Retaining more than the default number of snapshots will use additional storage space on the cloud appliance, which will cause it fill up more quickly.
