Delete an archive event

The following procedure is useful for deleting a single archive event or a small number of archive events. To delete large amounts of data, use the AF SDK ReplaceValues methods. For more information, see the AF SDK Reference topics AFData.ReplaceValues Method and PiPoint.ReplaceValues Method.

You cannot undo a delete. Deleting large amounts of data may affect availability of an online Data Archive server. If you are deleting data on a periodic basis, investigate the root cause and consider alternatives to deleting data in bulk. Possible alternatives could be using appropriate exception and compression settings, increasing the available disk space, moving older archives to a second tier storage, and so on.

Before you begin deleting real data, we strongly recommend that you practice deleting small amounts of data on a test system.

1. Back up your data.

2. In the Servers pane, select the server from where you want to remove data.

3. In the System Management Tools pane, select Data > Archive Editor.

4. Right-click the value you want to delete and select Delete.

5. Click Save.

   Note: There is no prompt to confirm deleting values.
