Why do you want backups?
Ransomware has maybe achieved extra for consciousness about information backups than some other cyberthreat.

Nevertheless, it’s not the one one. Take into account the next dangers, which backups will help to mitigate:
- Harmful information extortion assaults, partly pushed by the cybercrime-as-a-service ecosystem, through which information is exfiltrated and encrypted drives earlier than a ransom is demanded. ESET’s Risk Report for September to December 2022 discovered the usage of more and more harmful ways, comparable to deploying wipers that mimic ransomware and encrypt the sufferer’s information with no intention of offering the decryption key.
- Unintended information deletion by workers remains to be a problem, particularly when delicate information is saved to private units which don’t again it up. These units may be misplaced or stolen.

- Don’t neglect cloud (SaaS) information
