Question 333 of 527
LPIC-1 Devices, Filesystems and FHS Practice Question
A company is setting up a database server that requires high reliability and support for snapshots. The storage will be on a single large disk. Which filesystem is best suited for this requirement?
⚠ Common exam trap
Many exam-takers choose XFS for its high performance with large files, but they overlook that XFS lacks native snapshot support, while btrfs is specifically designed for advanced features like snapshots and self-healing on a single disk.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
btrfs
Btrfs (B-tree filesystem) is best suited for this requirement because it natively supports snapshots, checksumming, and copy-on-write (CoW) for high reliability, all on a single disk. Unlike other Linux filesystems, btrfs provides built-in snapshot and rollback capabilities without requiring an external volume manager, making it ideal for database servers needing consistent point-in-time backups.
