discussion Guide Plesk Plesk Backup Manager 403 Error and Backup Uploads Over 2 GB – Fix Guide 2025

[CL4Y]

If you encounter a 403 error while trying to upload a backup via Plesk Backup Manager, and your backup file exceeds 2 GB, don’t worry — we have a practical and reliable solution for you.

This issue usually occurs because Plesk Backup Manager limits large file uploads due to browser or configuration restrictions.
Fortunately, you can easily import large backups manually via SSH.

📂 1. Upload the Backup File to the Server​

First, upload your backup file with the .xml.tar or .tar extension to your server.
You can use FTP clients like WinSCP or FileZilla for this process.

Upload the backup to the following directory:

/var/lib/psa/dumps/

---

🖥️ 2. Connect to the Server via SSH​

Access your server through SSH using a terminal

🗃️ 3. Import the Backup Manually via Plesk Commands​

To register your backup file in Backup Manager, use one of the following commands:

plesk sbin pmm-ras –import-file-as-dump –dump-file-specification /var/lib/psa/dumps/backup_2010240048.tar

plesk bin pleskrestore --restore "/root/backup_22010240048.tar" -level server -ignore-sign

If your backup is password-protected, use one of these:

plesk bin pleskrestore --restore "/root/backup_22010240048.tar" -level server -ignore-sign -backup-password "password"

plesk bin pleskrestore --restore "/root/backup_22010240048.tar" -level server -ignore-sign -passwd "password"

---

💽 4. Restore from Backup Manager​

Once the import process completes successfully, the backup will appear under
Plesk Panel > Tools & Settings > Backup Manager.
From there, simply select the backup and restore it easily via the panel interface.
