Replicating a large database between sites could take several hours without WOM, and only several minutes with WOM.

WOM technology optimizes WAN traffic by eliminating redundant data transfers through inline deduplication, compression, and protocol acceleration, meaning only net-new or changed data blocks are transmitted. This dramatically reduces the volume of data crossing the WAN during database replication, compressing what would otherwise be an hours-long transfer into a matter of minutes. The statement is therefore true.

False is incorrect because WOM's deduplication and compression capabilities do demonstrably reduce large database replication times from hours to minutes by minimizing the actual data transmitted.
