World Backup Day 2026
1 free month for the first 15
World Backup Day turns 15. To celebrate, NimbusBackup is offering 1 free month of PBS backup to the first 15 contracts signed before March 31 at noon CET.
The 15th anniversary offer
15 years of World Backup Day = 15 free months, shared among the first 15 customers.
1 free month — First come, first served
The first 15 NimbusBackup contracts signed between now and March 31, 2026 at 12:00 noon CET get one full free month, capped at Double Drive PBS value (22 EUR/TB/month).
How to participate:
Subscribe
Choose your PBS plan (Single, Double, AirGapped…) and sign your contract before March 31 at noon CET.
Set up your backups
Start your first Proxmox backups to your NimbusBackup PBS datastore. Our team helps you get started if needed.
Share on LinkedIn
Post a testimonial about your backup strategy or why you chose offsite backups. Tag @RDEM Systems and @Richard Demongeot, with your PBS datastore hash.
Why LinkedIn?
The datastore hash proves you are an actual NimbusBackup customer. Your post helps raise awareness in the tech community about the importance of backups — that's the spirit of World Backup Day. No need to detail your architecture: a testimonial about why you back up offsite is enough.
