Which of the following is a common method for data recovery?

Filesystem analysis is a common method for data recovery because it involves examining the structure of the file system to identify how files are organized, accessed, and stored. Through this method, investigators can retrieve deleted files, uncover hidden data, and assess how data has been altered or corrupted. By analyzing the filesystem, practitioners can ascertain the integrity of data and potentially recover information that was believed to be lost.

In contrast, while data compression reduces the size of files for storage efficiency, it does not facilitate recovery of lost or deleted data. Data fragmentation refers to the way in which files may be split into pieces across a drive, which can complicate recovery efforts but is not a method of recovery itself. Digital archiving pertains to the long-term preservation and storage of data, which, while important for data management, does not focus specifically on recovering lost information.
