Domain is suspended every day by backup and not resumed

Symptoms

A domain becomes suspended in Plesk Control Panel every day without any manual actions.

Cause

A scheduled backup task is failing, while the option Suspend domains until backup task is completed is enabled in the backup task properties. The domain is suspended for the duration of the backup, but since the backup does not complete, the domain is not resumed.

Resolution

Log in to Plesk and disable the "Suspend domains until backup task is completed"  option in the scheduled backup task properties:

• For server-level backup: Tools & Settings > Backup Manager > Scheduled Backup Settings
• For reseller-level backup: Tools & Settings > Backup Manager > Scheduled Backup Settings (while logged in as reseller).
• For customer-level backup: Customers > "Manage Hosting" for customer > "Account" tab > Backup My Account and Websites > Scheduled Backup Settings
• For subscription-level backup: Subscriptions > subscription > "Websites & Domains" tab > Backup Manager > Scheduled Backup Settings
