Error Detection and Recovery
Archive files often include parity checks and other checksums for error detection, for instance zip files use a cyclic redundancy check (CRC).
Archive files are sometimes accompanied by separate parity archive (PAR) files that allow for additional error detection and recovery, particularly in recovery of missing files in a multi-file archive.

Famous quotes containing the words error and/or recovery:
“Meanwhile, if the fear of falling into error sets up a mistrust of Science, which in the absence of such scruples gets on with the work itself, and actually cognizes something, it is hard to see why we should not turn round and mistrust this very mistrust.... What calls itself fear of error reveals itself rather as fear of the truth.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“It’s even pleasant to be sick when you know that there are people who await your recovery as they might await a holiday.”
—Anton Pavlovich Chekhov (1860–1904)
