Wrapper for OSError raised while accessing backup files.
Borg does different kinds of IO, and IO failures have different consequences.
This wrapper represents failures of input file or extraction IO.
These are non-critical and are only reported (exit code = 1, warning).
Any unwrapped IO error is critical and aborts execution (for example repository IO failure).
