This is the foundation for a large set of planned features: snapshots, copy-on-write (COW) data, data deduplication, reflink copies, online data and metadata scrubbing, highly accurate reporting of data loss or bad sectors, and significantly improved reconstruction of damaged or corrupted filesystems. This work required changes to XFS's on-disk ...
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
Soft updates is an approach to maintaining file system metadata integrity in the event of a crash or power outage. Soft updates work by tracking and enforcing dependencies among updates to file system metadata. Soft updates are an alternative to the more commonly used approach of journaling file systems.
