checkpoint/restart

   Also found in: Acronyms 0.01 sec.

checkpoint/restart

A method of recovering from a system failure. A checkpoint is a copy of the computer's memory that is periodically saved on disk along with the current register settings (last instruction executed, etc.). In the event of any failure, the last checkpoint serves as a recovery point.

When the problem has been fixed, the restart program copies the last checkpoint into memory, resets all the hardware registers and starts the computer from that point. Any transactions in memory after the last checkpoint was taken until the failure occurred will be lost.


checkpoint/restart [′chek‚pȯint ′rē‚stärt]
(computer science)
The procedures for resuming a processing run after it has been halted either accidentally or deliberately.
