As the sibling says, 40 TB is not exactly "average home nas" territory. What I personally do, though I don't have 40 TB available even if I counted all my hard drives together, is I just have a second device that can hold the data and back up to it regularly. My NAS has something like 5 TB used. It's all synced to an old server that can hold about 8 TB and that's off most of the time (no fun living next to a jet engine). This cold server lives at my parents' house. My "really important stuff" on the NAS, which is a few hundred GB of pictures and such, is regularly backed up to a bucket with object locking. My "super important stuff", which is my company's accounting and other such documents, and lives on my laptop, is backed up to the live NAS and handled there as the really important stuff. I also back up my laptop to two normally offline external drives, one of which lives in my apartment and the other at my parents' house. Everything non-cloud is ZFS, so after each backup to an external drive or "cold NAS", I run a scrub to make sure it is still operational. The live NAS runs a scrub every Monday morning. Granted, this is not a "modern NAS" environment, since it made no sense to me to forego the free servers that my employer was going to send to the trash and buy some expensive off-the-shelf solution without the guarantees of ZFS (despite the issue TFA talks about). I know about power usage, but my live NAS eats less than 50W at idle (which is 99% of the time), so breaking even with the electricity prices in France would take forever. |
