Rewind Settings

From the Volume Resource Properties page, select the Rewind Settings button for enabling/disabling rewind, changing the rewind log location, associating volumes that should be rewound at the same time (as a single entity), setting the maximum age limit for the log file or setting NTFS compression for the selected replicated volume resource.

Field	Tips
Enable / Disable Rewind	Specifies whether to enable or disable rewind for the selected volume resource. Rewind is disabled by default.
Rewind Logfile Location	Specifies the folder where the rewind log file for this volume should be stored. The folder must not be on any volume that is part of a mirror or that is protected by SIOS Protection Suite - it must be on a volume that is writable whenever this volume is a mirror Target. Default is %extmirrbase%\RewindLogs. Note: The location of the log file must be changed prior to enabling rewind.
Compressed Logfile	Specifies whether the rewind log file should be created using NTFS compression. Select True to compress the logfile. Default is False. Note: The compress log file option must be set prior to enabling rewind.
Associated Volumes	Specifies which volumes should be rewound at the same time as a single entity. Associated volumes are specified in comma separated groups. For example, if you have two applications, one that relies on both the D: and E: volumes and another which relies on the P: and Q: volumes, then enter: DE,PQ. Note: In most cases, it is not necessary to change this setting. As long as your SIOS Protection Suite hierarchies contain the necessary volume resources that your applications depend on (which is normally the case), the rewind procedure will automatically associate those volumes when performing a rewind. You only need to override the default behavior if you have special volume associations that cannot be determined automatically by looking at the SIOS Protection Suite resource hierarchies.
Max Logfile Size	Specifies the maximum size, in MB, that this volume's rewind log will be allowed to grow to. A value of 0 specifies unlimited file size. Default is 0.
Max Logfile Age	Specifies the maximum number of minutes of data to be stored in the rewind log. A value of 0 specifies unlimited age. Default is 0.
Min Log Volume Free Space	Specifies the minimum amount of space in megabytes that should be reserved on the Rewind log file volume to avoid filling up the volume and running out of space. Default is 100MB.

Note: If Rewind is enabled and the DataKeeper Service is not running, a RewindDump file is created. Once the DataKeeper service starts, this RewindDump file is processed and removed, and the actual Rewind Log file is created. If you no longer want Rewind enabled on a particular volume, disable Rewind on that volume and then manually remove the RewindDump file.
