Well, to a certain extent, yes, say security experts! As it helps in recovering data when any untoward situation arises. However, the data backup must be done technically and must be efficient enough to be help users recover from a cyber incident with minimal downtime and public embarrassment.
Coming to the backup, there is a fundamental rule of following 3-2-1 rule. What it means is that organizations must maintain 3 copies of data out of which one must be the usable one and the other two must be backup copies stored on a different media and a cloud.
Some storage consultants do insist on keeping a copy of data at a different location geographically, as it assists during disaster recovery crisis when the primary site is flooded or experiences a catastrophic disaster.
Such a type of arrangement will also help in recovering information when the primary site is targeted by ransomware groups. However, in such tactics, the recovery is time-consuming and may yield losses to users in different form- mainly when the backed up data is offsite like cloud.
Remember, such offsite backup solutions can only help users in certain situations, like a malware attack. And are equally exposed to air gaps like corruption, errors committed by mis-configurations, improper handling of the media, inside threats and budget issues.
Merely proper planning and proactive-implementation can weed out such troubles and make your storage environment ransomware free.
