To perform a rewind operation on a replicated volume resource using the LifeKeeper GUI, right-click on the replicated volume resource and select Rewind Target Volume from the context menu. If you have the Properties panel enabled (View->Properties Panel), select the target of replicated volume resource to be rewound and click on on the resource toolbar. This will start the rewind operation.

The displayed Warning message will show the volume or volumes that will be rewound during the rewind operation. The target volume(s) will be paused and unlocked as part of the rewind operation. During the time that the mirrors are paused, the target server will not be eligible to provide SIOS Protection Suite recovery for the volumes. While data is being rewound on the target, all changes to the source will be tracked and written to the target by performing a Continue Mirror action. Click on Continue to proceed with the rewind operation or Cancel to exit the rewind operation. The table below shows the information that is required to perform the rewind operation.

Tips
Stop all applications on <Source> that are using volumes <driverletter(s)>?

Select Yes if you want SIOS Protection Suite to stop all applications running on the primary <Source> server that are using volumes specified by <driveletter(s)> as part of their SIOS Protection Suite hierarchy. Select No to leave applications running on the primary <Source> server.

Default is No.

Prepare to Rewind and Recover data for <volume tag> on<target> After SIOS Protection Suite completes the process of preparing the volume(s) identified by for rewind, click on Next to continue the rewind operation.
Specify Rewind Point

Choose a rewind timestamp from the list provided or type in the start time you want to use. There are many date and time formats accepted for this value including:

5/4/07 08:27

April 29 23:00

last Saturday 13:21

yesterday 08:23:17

The time string that you enter will be validated before being used. The progress bar at the bottom of the dialog indicates the state of the data in the rewind log as it is currently known. At the beginning of the rewind process, all data is unknown. As the data is rewound and advanced to various points in time, sections of the data are marked as good or bad depending on your test results with the various data sets.

Perform rewind SIOS Protection Suite is now rewinding the data on the target server to the rewind point specified from above. Click Next to continue with the rewind operation.
Please enter your comments on the test results; Comments are optional Evaluate the test results and enter any comments here. Comments will be stored and displayed in the list of Rewind Points to help you locate good data.
Is the data valid? Indicate whether the volume contents are now valid. The answer you provide will be used to construct the list of timestamps that you are given for future rewind/advance operations. SIOS Protection Suite tries to guide you to the latest known good data by limiting the start and end timestamps that are listed based on your answers to this question. If you choose Yes, you will not be given any choices that are earlier than the current selected timestamp. If you choose No, you will not be given any choices that are later than the current timestamp. If you are unsure whether the data is valid, choose Not Sure and the rewind points that you see will not be limited.
Processing result for rewind time below Storing evaluation and comments and adjusting Rewind Points interval. Click Next to continue with the rewind operation.

Proceed with recovery or try a different data set.

Select Next Action

You may choose to rewind or advance to a different timestamp or may stop rewinding and use the current state of the volume(s) for recovery. The progress bar at the bottom of the dialog indicates the state of the data in the rewind log as it is currently known. At the beginning of the rewind process, all data is unknown. As the data is rewound and advanced to various points in time, sections of the data are marked as good or bad depending on your test results with the various data sets.
Data Recovery To recover lost or corrupt data, you can leave applications running on the Source (primary) server or stop them as necessary. Manually copy any missing or corrupt data from the rewound Target (backup) server to the Source (primary) server. After copying has been completed, click on Next. The rewound volumes will be re-locked and the mirrors continued. This completes the rewind operation and data recovery operation.
