Gregory's Server@SiteRelEnby yeah.... well, CO2 is safer in that there's less asphyxiation risk, but neither thrills us. really humidity control is the big thing we think.

 @SiteRelEnby yeah... a long time ago we stored backups in AWS glacier. it was at a period in our life before we achieved financial stability, and at one point we were unable to pay the bill for a few months. we're sure the backups still physically exist (destroying them would cost money), but for practical purposes they are now permanently irretrievable. @SiteRelEnby also the originals they were backups of were destroyed during that same period, for reasons that shared a cause with it, so it's "real" data loss for us. @SiteRelEnby also over the next few years we're intending to accumulate, like, web scrapes and things of similar size, and even just the transfer cost for that would be prohibitive, so that's why we've been looking into very-high-volume removable media for our cold storage. @SiteRelEnby but yeah tier 1 is definitely going to be a RAID connected by SAN to our servers that we're going to have at some point, heh :) |
@irenes Yeah, plus it's easier to work with in preservation as well, as it collects low while nitrogen will diffuse out. Plus you end up with some pieces of dry ice, which is fun. Just don't chuck it in *with* the dry ice as freezing will kill the rubber too.
Myself, my backup strategy tries to be media-independent. 3 main tiers, plus a few extra things for critical hot data.
- NAS, running ZFS. Standard (NAS grade) hard drives, 1 hot spare, monitored by me
- Hot cloud backup. somewhat shallow, obviously depends on a major cloud provider, but one who won't disappear overnight.
- Cold cloud backup: AWS, so will likely exist until the heat death of the universe. Would be incredibly expensive to restore (glacier deep archive) but could be done slowly over time as storage is so cheap.
At some point I'd like to add some incremental snapshots on optical media with error recovery data (probably bluray or m-disc) but have other things that need doing right now.
