# Restore

You can restore your ArcSight Management Center configuration from a previous backup. These stipulations apply to restoring:

- The version of ArcSight Management Center used to restore the backup must be the same version used to create it.

- A backup performed on a root installation cannot be used to restore a non-root installation.

- For Software ArcSight Management Center, the install path of a restored Software ArcMC must be the same as the path of the backup, and the same root or non-root user must perform the installation as did the backup.

- For ArcMC appliances, the ArcMC to be restored needs to match the appliance model from the ArcMC backup.
- A Restore from one ArcMC backup may be performed to a different IP or hostname, subject to the stipulations above.

Note: When running backup/restore on a different appliance system (with the same model, e.g: C6600), the restore process will overwrite the destination's network information and certificate. Users must reset the certificate and reconfigure the network information.

To restore the configuration:

Note: Please restart ArcMC’s web process in order to begin with the data restore. The duration of the restore process will depend on the amount of data. Status can be checked in the log file:
- Software:`current/backups/restore.log`
- Appliances:`/opt/backups/restore.log`

1. Click Administration > Application > Restore.

2. Under Upload Backup for Restore, click Choose File.

3. Select your backup file.

4. Click Upload to restore the configuration from the specified backup file.

   Caution: The version of ArcSight Management Center used to restore the backup must be the same version used to create it.

5. On software , restart the ArcSight Management Center web process. On appliance, reboot the appliance.

6. Optionally, re-import the SSL certificate for each container. Click the icon to run the Certificate Download wizard and import the valid certificates. In addition, if a certificate mismatch is shown for any remote node, re-import the server certificate for the node.

After restoring the configuration:

- The cache size on the restore may be different from the cache size in the backup file. For example, after restoring the configuration, a managed node might receive more events or consume more cache.

- The container versions on the restore (if any) might be different from those in the backup file.

- The Cache column on the Connectors tab may take a few minutes to refresh the updated cache size for the Connectors/Collectors.

  Note: For information on restoring an appliance to its factory settings, see Restoring Factory Settings.
