Executing a Protected Group

Prerequisites

• Only protected groups in the Normal state can be executed.
• If Air Gap backup storage information changes, manually refresh the device information. For details, refer to Refreshing Resource Information.
• Information about storage devices must be refreshed the sites where the protected group resides to ensure that information about the protected group is refreshed successfully.
• Snapshots generated by eReplication are named in the SNAPSHOT-LUNNAME-SystemTime format, LUNNAME indicates the name of the protected group.
• Before executing a protected group, check whether the file system is associated with BCManagerNASAirGapSLA and disable SLA protection for the file system. Otherwise, the protected group fails to be executed.

Context

If daylight saving time (DST) is enabled on the eReplication management server, a DR protection task whose trigger time point falls within the DST shift period cannot be executed at the scheduled time. Details are as follows: UTC-08:00) Pacific Time (United States and Canada) is used as an example. The DST starts at 2016-03-12 02:00:00, and ends at 2016-11-06 02:00:00.

• If the start time of the protection policy falls within the first hour (2016-03-12 02:00:00 to 03:00:00) after the DST starts, for example, 2016-03-12 02:30:00, the protection group will be automatically executed with a delay of one hour, that is 2016-03-12 03:30:00.
• If the start time of the protection policy falls with the last hour (2016-11-06 01:00:00 to 02:00:00) before the DST ends, for example, 2016-11-06 01:30:00, the protection group will be executed after the DST ends for half an hour.

The automatic task of the protected group is triggered only within the time window of the port.

• Protected groups must be executed in off-peak hours. Execution when I/O activities are busy may fail.

• Protected groups in the Executing, Disabled, Locked, or Invalid state cannot be executed.
• If timetables are specified in the protection policies of a protected group, the protected group will be automatically executed based on the timetable. Perform the following steps to manually execute a protected group.

Procedure

1. On the menu bar, choose Protection.
2. Select the protected group for which you want to execute and click Execute on the Operation list.
3. In the Question dialog box that is displayed, read the content of the dialog box carefully. Then click OK.

   The protection policies of the protected group are executed immediately. On the Execution Records tab page, you can view the execution result and details.

   

   • If the protected group is in the Executing state for a long period, click in the upper right corner to refresh information.
   • After the protection group is successfully executed, a copy ransomware detection background task is generated. After the task is complete, you can view the copy ransomware detection status.

Result

After the protected group is executed, a historical record is generated on the Execution Records tab page. eReplication clears the execution records of each protected group at 00:00 every day. Only the latest 1000 records are retained. If the number of historical records exceeds 1000, the system deletes the earliest records.
