With all the recent news about systems being hacked,demanding ransom,where are the backups?
The technology has existed for many years to back up the system,including drive images,and archival data since last backup.
There should always be at least 3 days data backed up,with multiple copies kept off site for security.
RAID's are a good security method for on site security,where the loss of one or more hard drives is easily corrected by error detection.
Of course,this is not effective in DOS attacks,but if implemented it should prevent the impact of total loss of data.
