This topic applies to XInsight-managed systems running QSM 4.2 or later and XEVO 3.2 or later.

Replication tasks copy data from a source volume to a target volume on a remote storage system for backup or disaster recovery. The Replication Task page provides task status and progress information, source and target details, replication mode, task type, synchronization schedules, and traffic-shaping settings.

Go to Protection > Replication Task to create, monitor, and manage replication tasks.

Create a Replication Task #

Create a replication task to transfer data from a source volume to a target volume on a remote storage system.

Before you begin #

Make sure the source and target storage systems are connected to XInsight and that the required source and target volumes are available.

For remote replication, make sure the master controller on the source system can successfully ping the target system’s IP address.

The target volume must meet the following requirements:

• Its capacity must be greater than the capacity of the source volume.
• Its Volume Usage must be set to Replication Task.

When creating a target volume, select the required volume type and set Volume Usage to Replication Task.

Note: Configure Snapshot Space on the target volume to create a snapshot on the target after a replication task completes. The snapshot can serve as a recovery point for the replicated data.

For an existing block volume, go to Storage > Volume, select the volume, open Volume Usage, and change its usage from RAID to Replication Task.

Note: Only block volumes support changing Volume Usage after creation. File volumes cannot be switched between RAID and Replication Task after creation. To use a file volume as the target, select Replication Task when creating the volume.

1. Click the Create Replication Task button to create a replication task. Follow the instructions in the wizard to complete the process.
2. Select Local to copy data to local or Remote to copy data to another QSAN product, then click the Next button.
3. Define the task settings, source, and target:
   Enter a Task Name.
   Select the Source Pool and Source Volume to protect.
   Select the destination Target Pool and Target Volume.
4. Select a Schedule Type and configure the replication schedule as required. To reduce the impact on system performance, schedule replication tasks during off-peak hours when possible.

Edit a Traffic-Shaping Group #

Use Edit Shaping Group to create or modify the groups used to control replication traffic.

1. Click Edit Shaping Group.
2. Select the Profile to configure.
3. Specify the Traffic Limit Speed in MB/s.
4. (Optional) Under Peak Traffic Limit, toggle Enable to configure speed limits during specific peak hours.
5. Click Finish to save the profile settings.

Rename a Replication Task #

Change the name of an existing replication task to make it easier to identify.

1. Select the replication task that to rename.
2. Click Rename.
3. Enter a new task name and click Apply.

Synchronize a Replication Task Immediately #

Click Sync Now to start synchronization without waiting for the next scheduled operation.

Re-synchronize a Replication Task #

Use Re-sync when the source and target volumes are found to be out of sync. Re-synchronization performs a full copy of the source data to the target volume to restore data consistency between the source and target.

1. Select the replication task that to re-synchronize.
2. Click Re-sync.
3. Review the information in the confirmation dialog and confirm the operation.

Edit a Replication Schedule #

Change when and how often a replication task runs.

1. Select the replication task whose schedule to change.
2. Click Edit Schedule.
3. Modify the schedule settings.
4. Click Confirm to apply the changes.
