Backblaze b2, borgbase.com. There are also programs like dejadup that will let you backup to popular cloud drives. The alternatives are limitless.

I use Restic + Resticprofile to back up everything and store it on my local HDD.

Then, I use Rclone to sync the local repository to Backblaze B2.

Here's my general setup:

Resticprofile doesn't let me run other shell commands on a schedule, and because I wanted everything in a single configuration, I just created two new profiles which call the backup command. I then made the shell commands run before Restic, and then finally killed the instance before it got to actually run, which effectively does what I needed.

Tears... Natural, salty, wet tears...

I have an unraid server which hosts an docker image of Duplicacy. It is paid though for the web interface. And it backs up to Backblaze B2. I have roughly 175GB backed up, for which I pay $0.87 a month.

I use Duplicati connected to Storj with data volumes that incrementally get backed up once per month. My files don't change very often, so monthly is a good balance. Not counting my Jellyfin library, those backups are around 1 TB. With the Jellyfin library, almost 15 TB.

Earlier this year, I recovered from a 100% data loss scenario, as I didn't (and still don't) have space for physical backups. I have a 25 TB allowance, so my actual cost was €0. If I had to pay, it would have been under €1.

Regardless of service, if you don't test your backups, you have none.

Backblaze B2 for automatic syncing of all the little files

Glacier for long term archiving of old big files that never change

Duplicati to Backblaze B2 for the important stuff. For as far as the media library goes, no backup just local raid setup...

rsync.net is great if you need something simple and cheap. Backblaze B2 is also decent, but does have the typical download and API usage cost.

Borgbase with Borgmatic (Borg) as the Software. As far as I know the whole Borgbase Service is from a Homelab guy (with our needs in mind).

Also 3-2-1 rule!

My truenas backs up to B2 Backblaze. Set it up years ago and haven't touched it since.

I used to have everything backed up to a 2TB USB drive. Which I accidentally dropped down the stairs. I lost thousands of family photos and documents. That changed my backup perspective.

I now have a Synology NAS, with 12TB in a RAID5 array (for a bit of disk redundancy). All my home devices, Proxmox servers etc back up here. The NAS also holds a few TB of media. Attached to it I have a USB hard drive (also 12TB). The NAS gets fully backed up to the USB drive nightly.

I also have a remote Raspberry Pi with a smaller USB drive (4TB) attached to it at my brother's house (in another country), where I backup most of the contents of my home NAS. I don't back up the media, just the important stuff. I might have to upgrade to a larger drive...

Duplicati, to a friend's home server who lives in another town.
