The key to recovering from ransomware is preparation.
Obviously, the ideal is not to be victimized at all. To that end, identifying and addressing vulnerabilities in your organization's security posture, especially endpoints, servers, and networking systems and, perhaps most importantly, providing employees with education to help keep bad actors at bay, are critical for security in general. You may need to implement stronger access controls and patch known vulnerabilities.
But since no defense can guarantee 100 percent protection, recovering from ransomware requires pre-planning. First, you need to consider which systems and data are critical to your organization's operations and to prioritize backup and recovery accordingly, including (backup location, frequency, and storage media). Develop a data classification blueprint to identify which data is most important and should be backed up more frequently.
The key steps are then regularly backing up data to offsite or cloud-based storage, and testing backup and recovery processes to ensure they work. There are many solutions out there that provide these functionalities.
It's also important to have procedures and tools and people in place to isolate infected systems and components to prevent further spread of an attack. This may involve disconnecting infected machines from your network, disabling access to shared drives, or shutting down affected servers or workstations.
Once an attack has been contained, your recovery solution should, hopefully, make it relatively easy to restore systems from backup to their pre-attack status. It's important that your backup/recovery solution performs thorough scans to ensure that all malware has been removed.
Finally, regular risk assessments should help keep your strategy up to date. Consider a pen-testing service (if you don't have the expertise to develop a red team in-house). A good red team can simulate exploits and phishing to plant ransomware, and find unpatched network components. The results will often help you to fine-tune your software, incident response plans, and deal with vulnerabilities that have gone undetected.

Data backup involves copying and moving data from its primary location to a secondary location from which it can later be retrieved in case the primary data storage location experiences some kind of failure or disaster.
