Crash consistency using persistent memory programming libraries requiresprogrammers to use complex transactions and manual annotations. In contrast,the failure-atomic msync() (FAMS) interface is much simpler as it transparentlytracks updates and guarantees that modified data is atomically durable on acall to the failure-atomic variant of msync(). However, FAMS suffers fromseveral drawbacks, like the overhead of msync() and the write amplificationfrom page-level dirty data tracking.  To address these drawbacks while preserving the advantages of FAMS, wepropose Snapshot, an efficient userspace implementation of FAMS.  Snapshot uses compiler-based annotation to transparently track updates inuserspace and syncs them with the backing byte-addressable storage copy on acall to msync(). By keeping a copy of application data in DRAM, Snapshotimproves access latency. Moreover, with automatic tracking and syncing changesonly on a call to msync(), Snapshot provides crash-consistency guarantees,unlike the POSIX msync() system call.  For a KV-Store backed by Intel Optane running the YCSB benchmark, Snapshotachieves at least 1.2$\times$ speedup over PMDK while significantlyoutperforming conventional (non-crash-consistent) msync(). On an emulated CXLmemory semantic SSD, Snapshot outperforms PMDK by up to 10.9$\times$ on all butone YCSB workload, where PMDK is 1.2$\times$ faster than Snapshot. Further,Kyoto Cabinet commits perform up to 8.0$\times$ faster with Snapshot than itsbuilt-in, msync()-based crash-consistency mechanism.
