What are you using as a Google photos alternative? Currently I’m using Nextcloud but I’m thinking of switching to a more dedicated solution.
I mainly need to upload photos from my device automatically, have an UI to see and classify them, albuns and sharing.
It’s a dual drive redundant setup. Unless something catastrophic happens, I doubt both drives will go out at the same time. I could do an offsite backup as well, but just haven’t.
I was very satisfied with their pricing for offsite backups, and the ease of setup. Definitely worth a look.
The number of redundant drives actually doesn’t make much difference, but it does “help”. Instead of picturing individual drive failures, picture a house fire.
Also picture the next step after one of the drives fails – you’ll be copying all of that data off of your 1 good drive, putting a lot of stress on it. That drive is likely from the same batch, same age, etc. as the failed drive. The likelihood of your good drive failing during the recovery process is higher than one might like.
RAID is not backup :) And yes, it happened to me for 4 drives in a 16 drive system to fail in the span of just a few days (same batch).
