Data recovery from a ransomware infection is something we and our Partners do daily. We hear and read about what happens to some people who had a backup solution in place, the problem was that they never actually tested to recover the data; when they did it was too late. Realizing something was configured incorrectly or that the solution was not capable of getting the correct data needed. The other thing that happens is there was no integrity checking of the data, this is where the deep checking happens ensuring all the data is actually on disk and not written to a bad sector, or just completely missing in action. WholesaleBackup calls this a rigorous sync check and we can’t emphasize this feature enough, since hardware alone is not completely reliable. We actually build this into our S3 and Google Cloud clients by default so it happens every backup.
