> a year of weekly backups makes your 1 TB into 50, even if it's offline storage.
20TB (~18GB usable) drive is $370 + whatever power it will use
6 of them in RAID6 will give you 72TB backup storage, add extra copy and say extra drive as spare and that's 13*370 = $4810 USD for ~5 years + whatever power it will use, ~50-55W if idling most of the time and just writing backup once a day
I think people got completely disconnected from how it actually costs to run something because of vastly higher resell value of storage and bandwidth in the cloud.
> My own company struggles with that - throwing more storage on the live db is easy, so we've kept doing that for years, but pushing around multi-terabyte backups is getting cumbersome and we're going to have to slim down the data in prod even at the cost of engineer effort.
...but that's definitely a bigger part of that issue, cloud or not. Backup is slow, restore is slow, anything that involves any of the two is also slow
I hear this point from time to time, but you have to realise that consumer-grade hardware would never be used in any reasonable company. The business risk of not having a support contract in place is too high, so you need a support contract, which means buying supportable hardware, which means enterprise-grade gear, which means enterprise pricing. Your 50TB just turned into a 10TB array in a disk shelf plus some tape storage, at probably 20-30 grand total, plus support.
If you decide to be scammed by enterprise hardware vendors instead of hiring competent people because your management is a bunch of hacks that's your company problem.
Anyway Segate Exos SAS 20TB drive is $409, you can re-do math for "true enterprise" grade hardware. "Enterprise" drive from SAN vendor will be a normal hard drive with some bits in firmware changed so SAN can reject non-SAN-vendor rebrands. They die just the same, we had stacks of them to prove it.
Hell, some of our Intel enterprise NVMes died suspiciously quickly compared to other but that might be a fluke...
