How to allow resellers and customers to upload backup files without a valid signature?
By default, the option Upload backup files without a valid signature is available only for Plesk administrators.
If this option is unchecked, 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 a server.
- The file was created on another server.
- The file was created in Plesk lower than 11.5.
This option should be used only if you trust the backup that you are going to restore.
Resellers and customer do not have this option for security reasons: uploading a backup file without a valid signature may compromise security or disrupt the operation of a server.
If required, this option can be enabled for resellers and customers in the Plesk configuration file
Note: Enable this option only if you trust a backup creator. Uploading a modified backup can harm a server.
Connect to a 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 close the file.
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
