Just wondering what most people with NAS setups do in this regard. On the topic of the 3-2-1 rule (3 copies of data, on 2 different types of media, 1 off-site):
- Do you have a second full copy of your data on site, or do you consider RAID with redundancy good enough to satisfy the ‘2’ part of the rule?
- Do you back up everything to a cloud service for the ‘3’ part of the rule, and if so who do you use (and why)?
I’m just curious in general what NAS users are doing here, as clearly those with large storage pools (I’m talking tens of TB and up) are going to pay through the nose to have second and third copies.
Cheers :)
I only run one array/nas currently and the second nas is currently between builds and is half the size of the main array. I am do a lot of hardware salvaging. So I have a lot of missmatched drives. What i have done is organised the datasets by type, and below that by importance. This allows me to do a backup of the data I care most about. So, using all of these old hard drives, I find ones that have performance characteristics that are very similar, and make mirrors and raidz1 triples. I then cold store these with different people.
