<operating system> 1. An undigested and voluminous mass of information
about a problem or the state of a system, especially one routed to the slowest
available output device (compare core dump), and most especially one consisting
of hexadecimal or octal runes describing the byte-by-byte state of memory, mass
storage, or some file. In elder days, debugging was generally done by "groveling
over" a dump (see grovel); increasing use of high-level languages and
interactive debuggers has made such tedium uncommon, and the term "dump" now has
a faintly archaic flavour.
2. A backup. This usage is typical only at large time-sharing installations.
