Can ransomware infect backups?

Yes. Backups are a primary target — attackers deliberately corrupt, encrypt, or delete them to remove your recovery option, and ransomware frequently dwells undetected long enough to be copied into multiple backup sets. A backup job can report success while the data inside it is already compromised.

This is the gap Elastio is built to close. Backup vendors validate that a job completed, not that the data is clean; Elastio performs deep file inspection inside backups to confirm whether each recovery point is actually free of ransomware before you need it.
