Winckp: a transparent checkpointing and rollback recovery tool for Windows NT applications
01 January 1999
The goal of Winckp is to transparently checkpoint and recover applications on Windows NT. The definition of transparency is no modifications to applications at all, period. There is no need to get source code, or object code. It does not involve compilation, linking or generation of a different executable. We employ window message logging/replaying to recreate states that are otherwise difficult to recover by checkpointing alone. In the paper, we describe the design and implementation of Winckp, and present the challenges and limitations. The software is available for download from http://www.bell-labs.com/projects/swift
