A system administrator wants to minimize the risk of data corruption if the company server loses power unexpectedly. Which advantage is provided by selecting a file system that supports journaling?
It encrypts files for added security
It maintains a log of file system changes to help recover from crashes
It increases the maximum size of files that can be stored
Journaling file systems keep a log of pending changes. If a crash or power failure occurs before writes complete, the system can replay or roll back the log to return the file system to a consistent state, greatly reducing the chance of corruption or data loss. Compression, encryption, and larger file-size limits are unrelated features that do not come automatically from journaling.
