Right now, I have around 20TB of data in redundant ZFS mirrors, so I am somewhat protected against any single drive failing. Critical data is backed up at various cloud providers, but that’s only a few gigs of all my data.
Looking at S3 pricing, It seems rather unfeasible to back up my data there or on the other “big” cloud providers, as it would cost me around $180 with AWS or half of that with backblaze.
How and where do you guys back up your data?
It’s not really enabled right now, but my offsite backup is a combination of a Raspberry Pi 4B, a QNAP TL-D800C and a Tasmota WiFi power plug at a family member’s place.
I SSH in to the always-on Pi over a VPN connection, send a command to the Tasmota to turn on the QNAP disk shelf, do a
zfs sendand once it finishes it shuts down the disk shelf again.
