It's A Digital Disease!

Is it necessary to purchase a NAS if all I'm really interested in are the data integrity features (i.e automatic hash checking/recording, file self-healing, datascrubbing, etc.)? Currently I use MultiPar and backup my data to M-discs. However, I would like greater certainty that the hashes are accurate. For instance, I got a trojan recently and now I'm left questioning if the hundreds of files I've downloaded since my last backup have any data corruption, silent or otherwise. Since it's impossible to know without the features I listed previously, should I consider purchasing a NAS or is there a method I haven't thought of to ensure the same level of data integrity?
