Uploading Backup Files to Server
To upload a backup file to a backup storage within Plesk:
Go to Tools & Utilities > Backup Manager.
Click Browse and select the required backup file.
Note: Make sure you select the appropriate backup file format, which depends on the operating system on which Plesk is installed. On Linux/Unix systems, you should upload tar or zipped tar archives, and on Windows, ZIP archives.
The backup file will be uploaded to the backup storage.
