In this paper, we model the macroscopic behavior of database recovery using Markov renewal process theory. Specifically, four checkpoint setting schemes are quantitatively compared based on the reliability evaluation measure typified by system availability. Finally, numerical examples quantitatively verify the effects of failures caused by checkpointing and secondary failures generated during rollback recovery, in addition to the failures caused by system failures. © 2000 Scripta Technica, Electron Comm Jpn Pt 3, 83(9): 23–33, 2000
