Abstract
A computer-implemented method for mitigating write-back caching failures may include (1) detecting a failure that impairs at least one write-back cache that temporarily caches updates for individual files stored on a storage device, (2) identifying an attribute of an individual file stored on the storage device in response to the failure that impairs the write-back cache, (3) determining that at least a portion of the individual file is obsolete based at least in part on the attribute of the individual file, and then (4) performing at least one mitigating action with respect to the individual file to address the obsolete portion of the individual file. Various other methods, systems, and computer-readable media are also disclosed.
