Abstract
Systems and methods for verifying files in bulk in a file system. When files are represented by a segment tree, the levels of the segment trees are walked by level such that that multiple files are verified at the same time in order to identify missing segments. Then, a bottom up scan is performed using the missing segments to identify the files corresponding to the missing segments. The missing files can then be handled by the file system.
