Data Recovery involves the retrieval of data from storage media that has been accidentally deleted, corrupted, or rendered inaccessible due to hardware or software failures.
Techniques
File Carving: Method used to extract files from storage media based on file signatures and patterns, even if file system metadata is lost or damaged.
Data Imaging: Creating a bit-by-bit copy (forensic image) of storage devices to preserve original data and facilitate safe data recovery processes.
Logical and Physical Recovery Methods: Utilizing software tools and hardware techniques to recover data at both logical (file system level) and physical (sector level) layers.
Repairing Damaged File Systems: Techniques to repair corrupted file systems to facilitate data recovery without data loss.
Applications
Recovering Evidence: Essential for retrieving critical evidence from compromised or damaged digital devices in forensic investigations.
Legal Proceedings: Provides crucial digital evidence that can be used in court to support investigations, litigation, or regulatory compliance.
