With substantial volumes of critical files at stake, successful data backups are a key aspect of data protection. According to Aron Brand, CTO at CTERA, “effective protection must meet two critical requirements: it must retain previous versions of your files for a specific retention period (minimum of 30 days) where those files must be in a read-only repository so they cannot be deleted by a malicious software. And the archived copy must be physically separated from the main copy.”
