There are several things you can do to mitigate risk, though. Use a journaled filesystem (ext3, reiserfs, zfs, ntfs, etc.) Make sure you're using a battery-backed raid card Use a UPS, dang nabbit. If you're that worried about your data, it's worth the money. Oh, and also, make sure to set up and test the UPS's auto-shutdown feature on your server.

And the NAND flash translation layer is designed to be power-failure safe as well. But note that FAT file system, which is on top of NAND flash translation layer (NFTL), is not power-failure safe. To prevent a FAT file system to be corrupted, journaling mechanism for FAT should be enabled and used in your project. 1.
No. The most common type of journaling, called metadata journaling, only protects the integrity of the file system, not of data. This includes xfs, and ext3/ext4 in the default data=ordered mode.. If a non-journaling file system suffers a crash, it will be checked using fsck on the next boot.fsck scans every inode on the file system, looking for blocks that are marked as used but are not
NTFS recovery support ensures that if a power failure or a system failure occurs, no file system operations (transactions) will be left incomplete and the structure of the disk volume will remain intact without the need to run a disk repair utility. The answer then has to be that NTFS is safer, but not fail-safe. Share. Improve this answer
The Power-Safe (fs-qnx6.so) filesystem uses a copy-on-write (COW) technique to always maintain an uncorrupted version of the filesystem, even if a power failure occurs. For more information, see the Filesystems chapter of the System Architecture guide. The rest of this document explains: when corruption could occur; how to reduce HDD corruption
The File Allocation Table (FAT) file system is widely used file system in tablet personal computers, mobile phones, digital cameras and other embedded devices for data storage and multi-media applications such as video imaging, audio/video playback and recording. The FAT file system is not power fail-safe. This means that, the uncontrolled power loss or abrupt removal
There is a TRANSACTION SAFE mode available that is 100% power fail safe. First the intent to execute a file system operation is recorded, and then the operation is commited. If there is a power failure during the commit, the commit is restarted. The transition from record to commit is done via a single atomic SDCARD update.
emFile Journaling is an additional component which sits on top of the file system and makes the file system layer fail-safe. Journaling means that a file system logs all changes to a journal before committing them to the main file system and
