Selfhosted

I use the unlimited consumer backblaze with private key on a windows VM. I provision a 40tb iscsi connection to the VM from a NAS and all kinds of various homelab systems and devices store thier backups there. Works great and is the cheapest possible option at $9 a month.

Restic (or rustic) and Hetzner storage box 🤩

First copy on offline USB disk on my server itself. Disk is turned on, backup done, disk goes off. Once a day.

Second copy on a USB drive connected to an OpenWRT router of my home, the furthest away from the server (in case of fire, I could be able to grab either of the two).

Third copy offsite on a VPS.

I use restic & backrest with great satisfaction.

Local storage + a Veeam VBR VM

I started this past year with iDrive because of their incredible welcome deal if you switch from another service. I started a trial with Dropbox with the same email and sent them the requested screenshots for verification- they approved it. Spending $10 for the first year of 5TB

It's pretty slow on uploading, but it works. Customer service is attentive and caring. Probably going to go to a local NAS and a different online solution within the year. It's a nice cheap padding as I learn how to do this right. The intro deal might be worth it for you, too, though I don't think it's the best long-term option

I use borgbackup to create backups. I point backups to another home computer and borgbase.com. Borg itself is an amazing tool. I think you should learn how it works even if it doesnt end up being the best fit for you.

I've been using pcloud. They do one time upfront payments for 'lifetime' cloud storage. Catch a sale and it's ~$160/TB. For something long term like backups it seems unbeatable. To the point I sort of don't expect them to actually last forever, but if they last 2-3 years it's a decent deal still.

Use rclone to upload my files, honestly not ideal though since it's meant for file synchronisation not backups. Also they are dog slow. Downloading my 4TBs takes ~10 days.

Backblaze 200% of the time.

The only thing that sucks about backblaze is that they're not designed for enterprise. No account balances. No multi users.

Nobody that uses Wasabi?

I've been using rsync.net for a while now. It's been stable, fast, and relatively inexpensive. There's also the benefit that it's easy to script automated backups directly to it. For more Dropbox-like functionality, I have a Nextcloud instance that uses rsync.net as external storage. It's been great so far!

My current strategy might be a bit over the top,but it works.

I have two main entities that contain data worth backing up - the NAS and to a much smaller extend my Proxmox cluster (which is partly within my house,partly at Hetzner).

User PCs do not have any User data saved, they all work with network drives mapped to the NAS, only irrelevant amounts of data are stored on them that gets backed up via Free File Sync. For the Notebooks I use the same concept as we are using a WG VPN 99,9% of the time anyway,but some important folders get also synched via Free File Sync for offline use if no mobile connection is available.

For proper backups I have basically three classes of data that I maintain: Prio 1: The real real important stuff. Photos of once in a lifetime events, important documents, etc. Prio 2: The stuff you still don't want to loose. All other photos, the scanned documents, home folders, VMs/LXX backups, configurations, etc. Prio3: Everything else,mostly data that could be downloaded again. Easily. Movies, etc.

Prio3 data is currently only living in the NAS and does get backed up once in a while on a external hard drive. It's mainly backed up as I am lazy and in case the NAS craps out I don't want to reload all the stuff...that would take months.

Prio2 data gets backed up fully: For the NAS data: It gets backed up to B2 with versioning according to my needs (usually 3d,2w,3m,1y,but that depends highly on the source). Additionally full external hard drive backups every few weeks. (I would kill to get my hands on a proper tape drive again,I had one back in the day,but it was used and old and died) Some data is also stored on Synology C2 atm,but I will replace that soon with another cloud provider, likely Hetzner.

For Proxmox: Basically the same, but I use TUXIS instead of B2 and Hetzner instead of Synology C2. Additionally I have a old PC with Proxmox backup server which turns on once a week and safes the whole cluster before turning off again. In the future this PC is planned to replace the External hard disk's,but currently hard drive prices are insane.

For the P1 data: Same as above,but it's definitely staying on a second cloud provider. Additionally I also create archive blue ray disk's every few month. (Usually every 4). These go into the safe deposit box at my bank and additionally to a second storage location.

And of course I have detailed instructions about this in my will so even if both my wife and I die my kid can figure it out.

For devices like laptops and PCs. I use Urbackup to make backups.

For all the apps I host on Kubernetes I setup S3 backups to self hosted Minio.

I like S3 because I only pay for what I use and it has auto storage tiering.

I'm a long time user of jottacloud. It's not really meant for 10TB+, but works great for what I need it to do.

I'm on Pcloud, server with rsync+rclone to move files from file system to cloud and use it as a unified file system.

The lifetime storage offer from pcloud has been worth it for me and I even upgraded it from 2 to 12 TB
