Reliable cPanel backup solutions for large sites?

Hey everyone,

Following up on the 'cPanel backups still broken!' thread, I'm facing a similar but more critical issue with larger sites. My standard cPanel backups are consistently failing or taking an absurd amount of time, making them practically useless for disaster recovery. This is becoming a real headache for our overall web hosting management strategy.

• The Core Problem: While cPanel's built-in backup works okay for smaller sites, anything over ~30-40GB becomes a nightmare. Backups either time out, produce corrupted archives, or slow the entire server to a crawl for hours.
• What I've Tried:
  • Relying on the default cPanel full backup feature – Fails constantly.
  • Attempting partial backups (home directory only) – Still very slow and sometimes incomplete.
  • Manually zipping and downloading via FTP/SFTP – Super time-consuming and not scalable.
• My Specific Need: I manage several large client websites (some are 50GB+, one is approaching 100GB) on a dedicated server with cPanel. I need a robust and reliable system for automated daily/weekly backups, preferably offsite.
• Seeking Recommendations:
  • What are the most effective and reliable cPanel backup solutions for very large websites?
  • Are there specific third-party cPanel plugins (like JetBackup or R1Soft) that truly excel in this scenario without significant server overhead?
  • Any strategies for optimizing cPanel backup performance on the server side?
  • Recommendations for integrating with affordable and reliable offsite storage (e.g., S3, Backblaze B2, or specific backup services)?

I'm really looking for practical advice from anyone who has successfully implemented solid backup solutions for large cPanel installations. Anyone faced this before?
