Volume Shadow Copy Service (VSS) is a Windows feature that automatically creates backup copies or snapshots of computer files or entire volumes, even while they are in use. These snapshots enable users and system administrators to recover files that may have been accidentally deleted, modified, or corrupted. VSS operates in the background and is essential for backup and disaster recovery processes. However, VSS is often targeted by ransomware and other malicious software, which may attempt to delete shadow copies to prevent users from restoring their data after an attack. Proper configuration and protection of VSS are crucial for maintaining data integrity and ensuring reliable recovery options in the event of data loss or cyber incidents.
