Restore points

Restore points are useful for cases such as the following:

If a user error compromises data integrity, such as unintentionally dropping a table or inserting the wrong data into a table, you can restore the database to a state before the problematic transactions.
In the case of a failed upgrade, you can restore the database to its pre-upgrade state.
You want to create a number of backups while avoiding the overhead of storing copies of the database externally.

Restore points UI tour

You can view and manage restore points. After logging in to the OTCAD application, the home page appears. Select the More options button and Restore points. The Restore points page appears as shown in this image:

The Restore points page displays the following information:

Option	Description
a	+New folder Select this option to create a folder.
b	⋮ Select this option to add, edit, and delete all restore points.
c	⋮ Select this option to restore and delete a restore point.

Select the information icon i to view a summary of the restore point such as the folder name, the number of restore points to save, and the owner details.

Create a folder

A folder contains restore points. Before saving restore points, you must first create a folder to store them. You can then save restore points to the folder and select a restore point when restoring the database.

To create a folder, do the following:

In the Restore points page, select + New folder. The Create Restore points page opens.
In the Folder name field, enter a unique name for the folder.

In the Maximum restore points to retain field, enter the maximum number of restore points that can be saved on the folder.

Note

  If a folder contains the maximum number of restore points and a new restore point is saved, the oldest restore point in the folder is deleted.

Save the restore point. Do one of the following:
- Select Schedule.
- From the date picker, select the Start date and time.
- In the Repeat every field, specify the duration at which the restore point needs to be saved.
- From the Unit drop-down list, select the minute, hour, day, week, or month at which the restore point needs to be saved.
- Select the On day option and specify the day on which the restore point needs to be saved.
- Select the On option and specify the exact day and month on which the restore point needs to be saved.
OR
- Select Execute once to create the restore point manually.
Select Create.

Create a restore point

You can associate a restore point with an existing folder. Before you can save restore points, you must first create a folder to store them. Folders store the restore points in descending chronological order based on the times at which the restore points were saved. You can identify each restore point by its unique identifier or the index in the folder, where an index of 1 specifies the most recently saved restore point.

To create a restore point:

In the Restore points page, select ⋮ and +Add restore point. The restore point is created and displays the following information:
- Index - The serial number of the restore point in the folder.
- Timestamp - The date and time of creation of the restore point.
- Database version - The database version of the OTCAD application.
- ID - The unique identifier of the restore point.
- Status - The present status of the restore point. The status can be either Completed or Saving.
Note
```
  You need to have super user privileges to create folders and restore points.
```

Edit a folder

After creating an restore point, you can edit the details to suit your requirements.

In the Restore points page, select a folder.
Hover over ⋮ and select Edit. All the details of the restore point are populated. For more information about editing a folder, see Create a folder.
Select Update.

Delete all restore points in a folder

You can delete all restore points in a folder that are no longer in use or required.

In the Restore points page, select a folder.
Hover over ⋮ for a folder and select Delete all restore points.
In the Confirmation dialog, select Delete.

Restore a database from a restore point

After you have saved restore points to a folder, you can use those restore points to restore a database. The database is restored to the state at which the restore point was saved earlier.

The version of the revived database must be the same as or newer than the version of the database when the restore point was saved. After a database is revived, any restore point that was saved using a version newer than the version of the revived database will be invalidated. You can remove the invalidated restore points from the database.

The revive operation preserves existing folders, but their configuration, including restore point limits, are rolled back to their state when the restore point was saved. If a folder did not exist at the time of the restore point to which the database was revived, that folder is revived with default configuration settings—no restore point limit and dbadmin as the owner.

In the Restore points page, select a folder.
Hover over ⋮ for a restore point and select Restore.
Do one of the following:

Select Full restore to restore the complete database.
Select Restore.
In the Confirmation dialog, select Confirm. The estimated time to restore the database is displayed. After the database is successfully restored, it is displayed in the Restore points page with the status Completed.

OR
Select Specific objects to restore only specific objects in the database.
Select Create or replace to create a missing object or replace an existing object with the restored version.

OR
Select Coexist to restore objects without replacing the existing ones. New schemas store these restored objects.
In the Search for schema or tables field, enter the name of the schema or table to search in the current database.
Select Add objects to restore deleted objects. The Add deleted objects screen opens.
- In the Object name field, enter the name of the objects (schemas or tables) that need to be restored separated by a comma.
- Select Add to list. The deleted object appears as a check box in Deleted items. For example, to restore a deleted schema s2, enter s2. To restore a table t1 in the schema s2, enter s2.t1. Enter multiple deleted objects separated by a comma. * In the Data from current database area, the list of schemas and their corresponding objects is displayed. * Expand either a single schema or multiple schemas to restore objects.
Select Restore.
The objects selected for restoration are successfully restored.

Delete a restore point

You can delete a restore point that is no longer in use or required.

In the Restore points page, select a folder.
Hover over ⋮ for a restore point and select Delete restore point.
In the Confirmation dialog, select Delete.
