# Restore SMC Appliance backups

You can use the smca-restore command to restore Management Server backups, Log Server backups, and SMC Appliance configuration files on the SMC Appliance.

## Before you begin

If you are restoring a backup from a different version of the SMC Appliance, read the version-specific Release Notes before restoring the backup.

##

## Steps

1. Log on to the SMC Appliance command line.
2. Run the restore command.

       sudo smca-restore [options]

   You can append various options to the command to customize the backup process.
   - To specify the backup file to restore, use the -backup option.
   - To restore the Management Server or Log Server backup without restoring the SMC Appliance configuration, use the `-⁠nosmca` option.
   - To restore the SMC Appliance configuration without restoring the Management Server or Log Server backup, use the `-⁠smcaonly` option.
3. If you did not specify the backup file, select the backup file to be restored.
   The default backup file names have the following structure:
   - sgm_vVERSION.[BUILD]_YYYYMMDD_HHMMSS[comment]
   - sgl_vVERSION.[BUILD]_YYYYMMDD_HHMMSS[comment]
4. If the backup is encrypted, enter the password.
5. When the backup restoration has finished, restart the SMC Appliance if you are prompted to do so.
