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 :)
u/symean, a RAID (or NAS for that matter) system is NOT a backup solution and should never be considered as one.
With regard to your backup solution, you should then look into implementing a 3-2-1 backup model. One of the many example Videos for BackUps:

Having that said, what your BackUp model should be, ie. Full, Differencial, Incremantal, etc, will depend on your budget, storage capacity and end goals.
With regards to Backups best practices, see (for example) the following video (of the many, many other ones that find in youtube as well):
