Rewinding a VDB
Delphix Administration / HANA Environments and Data Sources / Provisioning VDBS From HANA dSources / Rewinding a VDB

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).

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 Datasets, select the VDB you want to rewind.

  3. On the Timeflow tab, select the rewind point as a snapshot.

  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.


Using TimeFlow Bookmarks


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


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