How to limit the number of server-wide backups stored in Plesk

Log in to Plesk.

Go to Tools & Settings > Backup Manager > Settings.

Change the value of Maximum number of full backup files to store according to your needs and apply the changes.

Note: The limit is related to full and scheduled backup files only (the number of incremental or manual backups is not limited).

Connect to the server via SSH or RDP

If it is Windows open CMD.

Update Maximum number of full backup files to store:

# plesk bin server_pref -u -max-backup-files 10

plesk bin server_pref.exe -u -max-backup-files 10
