Create snapshots based on a specific date and time - assure_mimix - 6.0

You can create a snapshot based on a time in the past. You can use this snapshot for data mining and object repair on the production server.

To create a snapshot:

1. On the recovery server, make sure all snapshot file systems are unmounted before trying to release the snapshot.

   rtumnt -C <Context ID>

2. Make sure that a snapshot does not already exist on the recovery server.

   scrt_ra -C <Context ID> -W

3. On the recovery server, enter the following command to create a snapshot based on a specific date and time.

   scrt_ra -C <Context ID> -D date

   The date format depends on the DATEMSK environment variable that is used by the recovery server.

   If you enter 06/15/18 09:33:40 as the date and 34 for the Context ID, the output is similar to the following:

   scrt_ra -C34 -D "06/15/18 09:33:40"
