Backup Tool

Use Open Dental's built-in tool to back up or restore data.

This tool can back up the following data:

  • The Backup tab is unavailable for Open Dental Cloud Users.
  • For InnoDB databases, this tool can only be used for backups. Restores cannot be done using this tool.

This tool does not encrypt data, so consider an encrypted device or encryption software to ensure data is protected while in storage. See Encryption of Data at Rest and in Transit. To use the backup tool, users must have the security permission Backup.


Exclude image folder from backup or restore: By default, the A to Z Folder is included in the backup or restore. To omit the A to Z folders from the backup or restore, check this box.

Save Defaults: Click to save the entered paths as the defaults.

Managed Backups: Unison BDR (Central Data Storage) is a preferred online backup service. Click the button to see more information. To remove this button, disable the Central Data Storage CDS Bridge, then check Hide Unused Button.


Backups should be run from the server that hosts the MySQL database. Running the tool from a workstation will likely result in an error, or the incorrect data being copied.

To back up data, first connect to the server, then insert the backup device (e.g., USB encrypted flash drive).

If the tool fails, try again by running Open Dental as an Administrator.

Backup database FROM this folder: Verify the database path to back up, it should contain the database currently connected. Typically it is C:\mysql\data\. Click Browse to select a different path. Only the connected database is backed up. Other databases in the path are ignored.

Backup TO this folder: Verify the drive or folder to back up the data to. For example, D:\. Do not back up to the same folder where the live database is located. We recommend utilizing a network path to another workstation or server in the office. Click Browse to select a different drive.

Click Backup. A message will display when the database backup is complete.

If the image folder is also being backed up, this process will start next. Once the image folder backup is complete, another message will display.


Backups should be tested regularly to ensure they restore correctly. It is recommended to test backups by restoring them to a workstation not connected to the office network. The name of the database being restored must match the name of the database being used to run the restore tool.

Restore FROM this folder: Enter the path the backup is currently stored. For example, if the backup is on a flashdrive, it might be D:\. Click Browse to select a different path.

Restore database TO this folder: Enter the path to place the backup. Typically it is C:\mysql\data\. Click Browse to select a different path.

Restore A-Z images to this folder: If the A-Z folder was backed up, enter the path to restore it to. Click Browse to select a different path.

Restore: Click to restore the database. See below for detailed instructions.

  4. Click Restore. A message will ask to restore from the backup on the external drive (with date).
  5. Click OK and the restore process begins.
    • The existing database is renamed using the current date (e.g., opendentalbackup_04_10_2023).
    • The database on the Restore FROM path is copied to the Restore database TO path and will become the active database.
  6. As soon as the restore is finished, close Open Dental.
  7. Restart Open Dental.
