Lesson 4 – Recovering metadata in Copy-on-Write filesystems
This lesson covers the difference between storing file metadata in a CoW-capable filesystem and in a non-CoW filesystem.
Additionally, the experiment devoted to know whether it is possible to reliably determine file timestamps on BTRFS is discussed in detail.
Based on the experiment result, we provide a set of rules sticking to which you can get the most complete picture of file timestamps on a CoW filesystem.
