Solution:

• Check backup limits: Some hosting plans have restrictions on backup sizes. Verify with your hosting provider to see if your backups are exceeding those limits.
• Ensure enough disk space: Backups fail if your account doesn’t have sufficient storage. Check your available space under Disk Usage.
• Create manual backups: Use Full Backup or backup your files and databases manually through File Manager and phpMyAdmin.
• Upgrade hosting plan: Consider upgrading your plan if you need more backup storage or resources.
