“3! 2! 1!” Is just what I say when doing some potentially deleterious action after rsyncing a few key directories to a separate volume

3 sticky notes telling me to “go get that incremental backup working”,
2 separate external hard drives,
1 month out of date

A usb stick and an old hard drive from 2009. The crackhead way of dealing with backups.

My current plan once new migration is completed:

Primary pool - 1x ZFS (couldn’t afford redundancy but no different to my RPI server). My goal is to get a few more drives and set up a RAIDZ1/2.

Weekly backup of critical data (eg. nextcloud) from primary pool to a secondary pool. Goal here is to get a mirror but will only be one drive for now.

Weekly upload of secondary pool to hetzner storage box via rsync.

Current server

1x backup to secondary drive (rpi) 1x backup to hetzner storage box via rsync

I dump my encrypted data to someone who probably practices 3-2-1 rule (which is Backblaze for me). I mean, these guys back up data for a living.

Currently only have pictures and documents stored, so everything easily fits on 1tb. One copy on my homeserver (unencrypted), one copy on my laptop (Luks encrypted), and one copy with rsync and a raspi at my parents (unencrypted). Might change encryption strategies to all luks.

4-2-1-1 for me I guess 🫣 or 4-2-2?

Two copies at home, synced daily, one of them in an external drive that I like to refer as the emergency grab and run copy lol

One at a family member synced weekly and manually every time I visit.

All of those three copies are always within a 10 kilometer radius in a valley overseen by a volcano so…

One partial copy of the so-critical-would-cry-if-Iost data is synced every few days to a backblaze bucket.

DO NOT follow my lead, my backup solution is scuffed at best.

3:

I have:

• RAID1 array w/ 2 drives
• Photos on the device that took them
• Photos on a random old hard drive pulled from an ancient apple mac.

2:

I’ve got a hard drive and flash memory?

Don’t have this at all, the closest is that my phone is off-site half of the day.

Sometimes: a laughing hyena.

If you don’t have tested backups, you don’t have a backup.

• Primary ZFS pool with automatic snapshots
  • Provides 3+ copies of the files via snapshots (3)
• Secondary ZFS pool at a different location replicates the primary
  • Provides more copies of the files (3)
  • Provides second media (2)
  • Is off-site (1)

Does this make sense?

my backup is staring longingly at LTO drives and wishing they would magically be affordable.

NAS (42tb RAID5), 2x 18tb spinning drives, 5tb SSD as daily driver, proton drive for critical stuff (2tb).

Not exactly 3-2-1 but it covers the same roughly

I rawdog storage. I RAID0 and forget. huehue.
