This topic describes the procedure for rewinding a VDB.

Rewinding a VDB rolls it back to a previous point in its TimeFlow and re-provisions the VDB.  The VDB will no longer contain changes after the rewind point. 

Although the VDB no longer contains changes after the rewind point, the rolled over Snapshots and TimeFlow still remain in Delphix and are accessible through the Command Line Interface (CLI). See the topic CLI Cookbook: Rolling Forward a VDB for instructions on how to use these snapshots to refresh a VDB to one of its later states after it has been rewound.

Prerequisites

To rewind a VDB, you must have the following permissions:

  • Auditor permissions on the dSource associated with the VDB
  • Owner permissions on the VDB itself

You do NOT need owner permissions for the group that contains the VDB. A user with Delphix Admin credentials can perform a VDB Rewind on any VDB in the system.

Procedure

  1. Login to the Delphix Admin application.
  2. Under Databases, select the VDB you want to rewind.
  3. Select the rewind point as a snapshot or a point in time.
  4. Click Rewind.
  5. If you want to use login credentials on the target environment other than those associated with the environment user, click Provide Privileged Credentials.
  6. Click Yes to confirm.

You can use TimeFlow bookmarks as the rewind point when using the CLI. Bookmarks can be useful to:

  • Mark where to rewind to - before starting a batch job on a VDB for example.
  • Provide a semantic point to revert back to in case the chosen rewind point turns out to be incorrect.

For a CLI example using a TimeFlow bookmark, see CLI Cookbook: Provisioning a VDB from a TimeFlow Bookmark.
