Architecture that is an efficient checkpoint process that performs backup and restore of checkpoint data items using bounded checkpoint buffers and log buffers in memory. Checkpoint processing can be performed using sequential inputs/outputs to a non-volatile storage medium (e.g., hard disk) on which the checkpoint files are persisted. Checkpoint processing is performed is in response to memory parameters that indicate the number or size of log entries accumulating in-memory relative to a memory threshold. In other words, given a bounded memory (e.g., cache), the rate of change of the log entries in the bounded memory triggers checkpoint processing.
