Abstract
The present disclosure is directed at systems and methods for copying a source volume to a target volume. The disclosed systems/methods facilitate copying the source volume to the target volume while an operating system is configured to write to the source volume, while ensuring that the resulting copy in the target volume represents a crash-consistent state of the source volume at a single point in time. According to some embodiments, the disclosed systems and methods reduce the amount of time that the operating system writing to the source volume spends in copy-on-write mode. The disclosed systems/methods can decrease the performance burden on the operating system (e.g., free up processing resources at the operating system for other tasks), while also decreasing the amount of memory required for the copying process.
