Guidelines and prerequisites for replication

Refer to the following important notes and guidelines for understanding and using replication in QoreStor.

  • TCP Port Configuration—If you plan to perform replication operations across a firewall, the replication service requires that the following fixed TCP ports be configured to support replication operations:
    • port 9904
    • port 9911
    • port 9915
    • port 9916
  • DMAs and Domain Relationships — To allow replication storage information to be viewed by a corresponding data management application (DMA), the target QoreStor system must reside in the same domain as the source QoreStor system in the replication relationship.
  • Replication Limits — Refer to the QoreStor Interoperability Guide for details about the supported system limits for replication. For a definition of connections and streams, see Streams and connections.
  • Version Checking — The QoreStor software includes version checking that limits replication only between other QoreStor systems that run the same system software version. If versions are incompatible, the administrator will be notified by an event, and replication will not continue.
  • Storage Capacity and Number of Source Systems — Be aware that the storage capacity of the target QoreStor system is directly affected by the number of source systems writing to its containers, and also by the amount being written by each of these source systems.
  • Bandwidth limiting — Refer to the replication command in the QoreStor Command Line Reference Guide for information regarding limiting bandwidth consumption for replication.
  • MTU Setting — Primary and secondary replication targets should have the same network maximum transmission unit (MTU) setting.

Adding replication relationships

When configuring replication for object containers, replication must be added from the source system. Also once replication is added for Object container, the replica container is not accessible. Once replication is deleted then the replica becomes accessible over S3 to the clients.

NOTE: For DR-to-QoreStor replication, configure replication from QoreStor.

To add a new replication relationship, complete the following steps.

  1. In the navigation menu, click Replications.
  2. Click Add Replication.
  3. To define the Source Container, select the Local or Remote option.
    • If you select Local, select the local container from the drop-down list.
    • If you select Remote, configure the following settings:
      • Username—enter the username for the remote system.
      • Password—enter the password for the remote system.
      • Remote Machine—enter the domain name of the remote system.
      • Click Retrieve Containers.
      • Select Remote Container—Select the remote container from the drop-down list.
  4. For Encryption, select one of the following encryption options to encrypt the data as it is replicated: None, AES 128–bit, or AES 256–bit.
  5. Under Target Container, define the target replica container by configuring the following settings.
    • Username—enter the username for the remote system.

      NOTE: The credentials used need to be either the admin or administrator account.

    • Password—enter the password for the remote system.
    • Remote Machine—enter the domain name of the remote system.
    • Click Retrieve Remote Containers.
    • Select the remote container from the drop-down list.
  6. Click Next.
  7. Review the summary and click Finish.

NOTE: For information about starting and stopping replication, see the topic, Starting and stopping replication. For information about scheduling system operations such as replication, see Understanding system operation scheduling.

Configuring replication schedules

By default, replication of any newly written files in the replicated container will occur when QoreStor detects three (3) minutes of idle time. If you wish to constrain replication activities to a specific schedule, you can configure replication schedules on a weekly basis for individual replication-enabled source containers.

NOTE: It is recommended that you do not schedule the running of any Replication operations during the same time period when Cleaner or data ingest operations will be running. If you do not follow this recommendation, the time required to complete the system operations or system performance might be affected.

To configure replication schedules using the UI:

  1. On the left navigation menu, click Replications.

    The Replications page is displayed, listing all configured replication relationships.

  2. The configured replications are displayed.
  3. To configure or edit the replication schedule, click Details.
  4. Click Edit Schedule.
  5. For each day of the week, click the time selector field. Select the From and To times to configure a window during which replication can run. Click Set.
  6. Click Save Schedule.

To configure replication schedules, complete the following steps.

  1. Access the QoreStor command line interface.
  2. Use the QoreStor command line interface (CLI) to create and delete the replication schedule. The available commands are:
  schedule --add --day <Day of the Week> --start_time <HH:MM> --stop_time <HH:MM> --name --replication  

  schedule --delete --day <Day of the Week> --name --replication

For full details on running the cleaner schedule commands, help is available by entering:

  schedule --help

You can view replication details and status on the Replications page in the QoreStor GUI by selecting a replication and clicking to expand and view details.

Viewing replication information

In the QoreStor GUI, the Replication page displays current information about replication relationships for data containers in your QoreStor system.

To view replication information

  1. In the navigation menu, click Replications.
  2. The configured replications are displayed.

    Using the or toggle in the upper-right corner of the Replications pane, you may switch between tile and grid views.

  3. To view more detailed information and additional options, click the elipsis icon and click Details.
    • Tile view - the ellipsis icon is to the right of the source container. You may also click the Details button to the right of the configured replication.
    • Grid View - the ellipsis icon is in the Actions column.

    The information below is displayed:

    • Replication Source and Target Containers
    • Replication Source and Target Systems
    • Replication Schedule
    • A Summary showing:
      • Cloud Enabled status
      • Cloud Storage Group
      • Peer Status
      • Estimated time to sync
      • Last sync time
      • Schedule status.
    • Network Savings
    • Replication Throughput
    • Transfer
