How to reset Database Lab clone's state

With Database Lab clones, you can verify any changes and without any risks for the source database (such as production).

GUI​

  1. Connect to your clone and execute DDL or DML query – for example, drop some table: Database Lab engine page / Create clone
  2. At the Database Lab clone page, click the Reset button: Database Lab engine page / Create clone
  3. Wait for the OK status and connect to your clone again. The data will be recovered to the initial state: Database Lab engine page / Create clone

CLI​

Before you run any commands, install Database Lab CLI and initialize configuration. For more information, see Install and initialize Database Lab CLI.

Reset a clone​

If you need to reset the clone to the initial state and discard all changes were done (revert to the snapshot that was used for clone creation):

dblab clone reset CLONE_ID

Result:

The clone has been successfully reset: CLONE_ID

To reset to the latest available snapshot (feature available in DLE version 2.5+) – this is especially useful for long-living clones because you can get the fresh version of data not changing the DB credentials (including port) of your clone:

dblab clone reset --latest CLONE_ID

Finally, if you want to reset the clone's state using specific snapshot:

dblab clone reset --snapshot-id SNAPSHOT_ID CLONE_ID
caution

The parameters --latest and --snapshot-id must not be specified at the same time.
