#321rule — Public Fediverse posts

Is there a cloud version of the 3-2-1 backup rule?

For example, I have production data in a managed database data hosted at some megacorp cloud service with point in time recovery and daily snapshots.

This protects from our own mistakes and to some extent the very likely event of megacorp making a mistake.

What else do I need?

Following the "3-2-1 is the minimum" rule, I've expanded my VPS container backup strategy:

✅ Hetzner Cloud (Borg) → Offsite long-term storage
✅ Synology NAS (rsync) → Local fast recovery

The new setup does nightly automated syncs of all /opt/containers/ data to my Synology - with deduplication and all the bells and whistles! 📦

Particularly clever: hardlinks for space-efficient snapshots and morning email reports. Now I know right with my coffee ☕ whether all backups ran cleanly.

Lesson learned: Cloud-only is good, but having a local NAS mirror for quick restores is pure gold! 💪

How do you solve this in your setups? Also multi-tier or everything to cloud?

On #WorldBackupDay, a reminder of the 3-2-1 Rule:

• 3 copies of each file exist, as a minimum
• 2 copies are on physically different storage media
• 1 copy is on a storage medium that is physically located “elsewhere”

As an absolute minimum, suggest the following to people without appropriate protection:

• Get 2 external disks
• Make regular backups on one of them, while the other remains stored “elsewhere”, with someone trustworthy
• Have the two disks swap places regularly

Strictly speaking, the “1” of the 3-2-1 rule is only maintained if you take the disk that has just been used for the backup to “elsewhere”, and return with the other one (not the other way round).

For secure data backup, here’s how to do the 3-2-1 rule right

"The venerable 3-2-1 rule for backing up data remains a tried-and-true method for ensuring the integrity of copied data that is essential to disaster recovery efforts, but it has to be done properly."

I'm honestly not sure how I haven't crashed yet, but I think that happens tomorrow. This is training for #Defcon so I only need to follow the 2-1 rule.
