Selfhosted

I run a Windows 10 vm that shares a drive with samba, I borg/kopia backup everything to it, and it runs the backblaze client which then backs up to Backblaze personal backup.

Everything local is synced to NAS.
NAS is backed up to external USB-HDD with versioning (Hyperbackup).
NAS is backed up to Hetzner Storage via Kopia with versioned Snapshots off-site.

My server is now up to 100 and something tb of storage. About 50% used. Raid 6. (Yes raid isn’t a backup. I know) Mainly media. Movies, tv, music, Books/audiobooks.

I’ve separated our media storage vs OS.

I only backup my OS and configs. It goes to an on-site nas.

If my media library dies, I’ll just slowly re-download what people want.

If I lose my os, I have one backup, other wise I’m off to work rebuilding that too.

I’m happy to pay for iCloud at this stage to backup and store sentimental or critical things.

Urbackup for workstations, and Proxmox Backup Server for my 2 Proxmox hosts.

Both configured with borg backups to rsync.net.

I haven't configured it yet, but I am planning on using rsync.net for my Synology as well (Which is mostly archive storage)

I'm using AWS S3. I've got a script on my RPI that runs daily and uses the AWS CLI to sync my photos etc to there, and stores it as Glacier storage.

It's about US$9 per month for 800GB of storage, at that time it was the cheapest and most convenient.

My personal approach to offsite is to have my NAS, running TrueNAS Core, automatically encrypt and back up its primary pool directly to an S3-compatible service called Wasabi.

I've also considered setting up a small box with a 12TB hard drive at my parents' house a few miles away for ZFS replication.

I have a Hetzner storage box which also has a borgbackup server installed.

I've got a Tarsnap account backing up my especially important data every night, which is admittedly only a couple of gigabytes of scans of important documents, hard to replace files, etc. It's doing snapshot-style backup with a backup for every day in the last week, every week of the last month, every month of the last year, and the last three years. Paying less than a dollar a month for it, so it's working out.

That stuff also gets rsync'd each night onto my NAS, which has its own automated LVM snapshot system going on along the same lines, and I'm using syncthing to mirror it onto my other PCs as a final last-ditch backup (and in case I need it elsewhere). Finally, there's an external hard drive I keep manual backups on every once in a while.

Larger datasets that aren't really stuff I want to pay for on the cloud (14 TB worth) just get stored on the NAS and a drawer full of external hard drives. Not ideal, but it's just way too much data.

Gocryptfs + Rclone sync to B2

Used to use freefilesync for offsite backups, but haven't in a while. Wanted to replace that with a native BTRFS offsite sync tool like Btrbk, but haven't got around to it yet

I won't go into my solution here, but the only tip I'll give you is don't use cloud based storage. Restoring is slow if we're talking terrabytes, it's expensive compared to buying a disk and your data is never truly safe.

Buy another drive, backup to it and have it on a rotation schedule. I keep my "offsite" backup in the boot of my car. If I'm not at home I'm usually away with my car.
