How to allow resellers and customers to upload backups without a valid signature?
Why does the option Upload backup files without a valid signature not available for resellers and customers?
The option Upload backup files without a valid signature is not available for resellers and customer by default due to security reasons.
Uploading such a file may compromise security or disrupt the operation of the server. If this checkbox is cleared (by default), Plesk checks a backup file for a valid structure and signature and does not restore it if any of the following problems are found:
- The file is corrupted.
- The file was modified manually after downloading from the server.
- The file was created on another server.
- The file was created in a Plesk version earlier than 11.5.
This option should be used only if you trust the backup that you are going to restore.
If required, this option can be enabled in the Plesk configuration file
Note: Enable this option only if you trust a backup creator. Uploading a modified backup may harm the server.
Connect to the Plesk server via SSH.
Open the file
/usr/local/psa/admin/conf/panel.iniin any text editor and navigate to the record
allowRestoreModifiedDumps(by default it is located at the end of the file):
Uncomment the line and set the value to "on":
CONFIG_TEXT: allowRestoreModifiedDumps = on
Save the changes and exit the text editor.
Note: If the option Upload backup files without a valid signature is no longer needed by resellers/customers, disable this option by commenting out the line
allowRestoreModifiedDumps = on in the file
