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

My nas is a second copy of all my data, nothing only exists on the nas. The nas is also is slowly uploading to backblaze, data limits are slowing my progress. My photos which I feel are the least replaceable are automatically backed up to my nas , Google photos, and amazon photos, with manual backup to my desktop, and manual backup to an external hard drive that is stored in a fire resistant box.

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.

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

3: RAID-1 pair + manual periodic sync to an external HD, roughly monthly. Databases synced to cloud.

2: external HD is unplugged when not syncing

1: External HD is a rotating pair, swapped in a bank box, roughly quarterly. Bank box costs $45/year.

If the RAID crashes, I lose at most a month. If the house burns down, I lose at most 3 months. Ransomware, unless it’s really stealthy, I lose 3 months. If I had ongoing development projects, a month (or 3) would be a lot to lose, and I’d probably switch to weekly syncs and monthly swaps, but for what I actually do - media files, financial and smart-home data, 3 months would not be impossible to recreate.

All of this works because my system is small enough to fit on one HDD. A 3-2-1 system for tens of TB starts to look a lot like an enterprise system.

I use Proxmox Backup Server for my backups. Everything backups to 1 system at home. I then sync the data store to a little NAS I have at a family members house across town and also to a cheap storage VPS on the other side of the country. I also do a manual sync of the data store to a single external drive that I manually connect and disconnect.

None of my data hoarding files are backed up as that would cost way too much. That could change if I ever find a killer deal on an LTO8 or better drive and tapes.

I know that Hetzner has some decently priced Storage Boxes that you can mount using rclone and then backup to. Keep in mind that latency will be a factor so it could be slow.

My day-to-day stuff stays in sync via syncthing on my two laptops, my desktop and my home server. They all run btrfs, so I won’t be syncing any flipped bits around.

Home server rsyncs from my VPS once a week. When that’s fine, it rsyncs itself over to a hetzner storage over sshfs+gocryptfs.

Four copies at home, one in the cloud.

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?

1:

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

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

Everything backs up to a Synology diskstation (with disk redundancy). The Syno’s Hyperbackup makes backups of critical stuff stuff to the cloud weekly. In the case of my self-hosted stuff, it’s mostly the share storage where all my docker volumes map to. Also workstation backsups, home assistant backups, phone photos, etc.

A back up of the temporally replaceable stuff (everything not covered above) which is hosted from the Diskstation, is made to an external drive a few times a year and stored off-site the rest of the time. This isn’t 3-2-1, but its close enough for my needs.

1 backup on a local, Independence disk. 1 backup on a HDD connected to an OpenWRT router at the other end of the house 1 backup on my remote vps.

Restic+backrest

Sftp for remote endpoint

I rawdog storage. I RAID0 and forget. huehue.

Wow, a lot of variation in this thread!

I get all my data to my server, then from there I have borgmatic do incremental backups to a backup drive on the same machine (nightly cronjob).

From there I use Rclone to get the encrypted borg backup to Backblaze B2 for cloud storage.

So for 3 2 1, my 3 copies are the original, the local backup, and the cloud backup.

My 2 media are local hard drives and cloud storage (I think it’s fair to consider this a different kind of media).

And my 1 offsite is the cloud backup.

Now I’m dumb and have a fear of screwing something up so I have also started burning M-Discs of my critical data (everything except TV/movie/music stuff I can redownload). Though this was a lot more expensive than I was expecting, because of aforementioned me being dumb I already screwed up two discs (they are write once). I’m also doing two copies of each disc.

Also I have photos/home videos additionally stored in ente, they are super important to me and I wanted a separated copy someone else is looking after.

I use Kopia to B2, then on a monthly basis I copy the current Kopia repo to an external drive that’s otherwise kept offline in my house.

iDrive e2 with duplicati and manually to an external SSD with rscyn every so often.

I was planing on asking a friend to setup a server at their home, but I feel somewhat comfortable with the current solution.
