Uploading Backup Files to Server

To upload a backup file to the Plesk’s storage, go to Tools &
Settings > Backup Manager and click Upload. Before
starting the upload, Plesk will prompt you to specify the following
backup parameters:

• Backup file. Click Choose File to select a backup file you
  want to upload. By default, the maximum file size is limited to two
  gigabytes. If you need to upload a larger file, change the maximum
  upload file size in the Plesk settings (more information can be found
  at Advanced Administrator Guide
  (Windows)
  and Advanced Administrator Guide
  (Linux)).

• Upload backup files without a valid signature. 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.

  Selecting this checkbox allows restoring data from such files. Select
  it only if you trust the backup source because uploading such a file
  may compromise security or disrupt the operation of the server.

  Note: You can only restore backups made in Plesk Onyx 17.0 and later.

• Use password protection. Select this checkbox if you used a
  password for protecting the backup file and are going to specify the
  password when uploading the file.

• Password. Enter the password that you used for protecting the
  backup data.

  Note: If you do not select the Use password protection option for a
  password-protected backup or provide an incorrect password, Plesk
  will upload the backup to the server anyway. During the backup
  restoration, you will be prompted to enter the password again.
