Setting up replication and failback jobs

After the replication service is deployed, replication and failback jobs have initial default settings. You can modify the above default settings for asynchronous replication jobs (including jobs triggered by asynchronous replication plans and jobs generated during synchronous replication) as well as fault handling jobs based on your actual needs.

Procedure

1. In the left sidebar of the Backup & DR page of AOC, select Settings to enter its management page.

2. In the pop-up dialog box, select the deployed replication service in the left sidebar, and then click Job settings to configure the replication and failback jobs for the replication service accordingly.

   • Simultaneously-executed job limit

     • Max async replication jobs: Specify the maximum number of asynchronous replication jobs that can be executed simultaneously by the current replication service. Modifying the maximum number of replication jobs does not affect the running asynchronous replication jobs.
     • Max failback jobs: Specify the maximum number of failback jobs that can be executed simultaneously by the current replication service. Modifying the maximum number of failback jobs does not affect the running failback jobs.

   • Automatic retry limit

     Choose whether to automatically retry after a job fails. Automatic retry is applicable to multiple types of jobs, including replication, failover, failback, and permanent failover. This feature is enabled by default. Once enabled, if a job fails, the system will automatically retry a failed job until it succeeds or the maximum number of retries is reached.

   • Load control

     Choose whether to enable the transfer rate limit for replication and failback jobs. This feature is disabled by default. That is, no limit is applied to the transmission speed. Once enabled, you can individually configure the maximum transmission speed for replication and failback jobs. The value must not be lower than 2 MiB/s.

     • Asynchronous replication limit: Set the maximum transmission speed for all asynchronous replication jobs executed simultaneously by the current replication service. Leave it blank or set it to zero for no limit.
     • Failback limit: Set the maximum transmission speed for all failback jobs executed simultaneously by the current replication service. Leave it blank or set it to zero for no limit.

3. Click Save to save the replication job configuration.
