To open the Attach Multiple Backups Wizard, click Attach Backup Files located under the Attach Multiple Backups option. Follow these steps to create a VDB based on data from specific backup files:
- Backup Files:
- Click Select to choose a Host Instance from the displayed list.
- Click Browse, select the backup files (.bak & .safe) from the file explorer dialog box or enter manually the files you prefer in the text box and click Add to display them in the Selected Backups section below.
- The Encryption Settings option is available when the chosen backup sets were encrypted during their backup.
- Click Remove to delete all selected backup files from the display. A dialog box opens to confirm the backup removal.
- Click Next to continue.
- Point in Time:
In this step, the user sets a specific restore point in time. The following options can be performed:- Use the point in time slider to select the backup sets you need. This ensures you are not restoring data time-stamped with dates later than the point in time you specified.
- You can enter manually the specific point in time to restore. There are two ways to pick date and time to restore file(s): By Date or by LSN.
Click Next to continue.
When choosing Date use MM/DD/YYYY hh:mm:ss format. And for LSN use '#:#;#' format.
LSN (Log Sequence Numbers) is used internally during a RESTORE sequence to track the point in time to which data has been restored. When a backup is restored, the data is restored to the LSN corresponding to the point in time at which the backup was taken.
- Create As:
- The Host Instance textbox displays the instance name that hosts the VDB, by default.
- In the Virtual Database Name textbox, type a unique name for your VDB. Click Database Files... to customize the location where to store the files for your new VDB and click OK.
- Enter a Description.
- Click Next to continue.
- Summary:
- Confirm the display information in the Summary step.
- Click Prev to go back to previous steps and edit the information, select Cancel to cancel the process and close the wizard, or click Finish to start the process.
- A progress bar displays showing the status of the process. When the process completes, the status changes to Complete.
