I have recently repurposed and old Hp Stream to a home server and successfully run Immich. I really like it and even a small 500GB disk is way more than the 15GB Google offers.
My issue though is about backup. I would only be comfortable if all the data is backed up in an off-site server (cloud). But the back up storage will probably cost as much as paying for a service like ente or similar, directly replacing Google photo.
What am I missing? Where do you store your backup?

There was a good blog post about the real cost of storage, but I can’t find it now.
The gist was that to store 1TB of data somewhat reliably, you probably need at least:
- mirrored main storage 2TB
- frequent/local backup space, also at least mirrored disks 2TB + more if using a versioned backup system
- remote / cold storage backup space about the same as the frequent backups
Which amounts to something like 6TB of disk for 1TB of actual data. In real life you’d probably use some other level of RAID, at least for larger amounts so it’s perhaps not as harsh, and compression can reduce the required backup space too.
I have around 130G of data in Nextcloud, and the off-site borg repo for it is about 180G. Then there’s local backups on a mirrored HDD, with the ZFS snapshots that are not yet pruned that’s maybe 200G of raw disk space. So 130G becomes 510G in my setup.
I backup to a external hard disk that I keep in a fireproof and water resistant safe at home. Each service has its own LVM volume which I snapshot and then backup the snapshots with borg, all into one repository. The backup is triggered by a udev rule so it happens automatically when I plug the drive in; the backup script uses ntfy.sh (running locally) to let me know when it is finished so I can put the drive back in the safe. I can share the script later, if anyone is interested.
I use Backblaze B2 for my backups. Storing about 2tb, comes out to about $10/mo, which is on par with Google One pricing. However, I get the benefit of controlling my data, and I use it for tons more than just photos (movies/shows etc).
If you want a cheaper solution and have somewhere else you can store off-site (e.g. family/friend’s house), you can probably use a raspberry pi to make a super cheap backup solution.
If you have 1tb+ of data you can get a cheaper option just by moving to hetzner (also, even storj is cheaper than backblaze)
