	att_abstract={{This paper argues that the network latency due to synchronous replication is no longer tolerable in scenarios where businesses are required by regulation to separate their secondary sites from the  primary by hundreds of miles. We propose a semantic-aware remote  replication system to meet the contrasting needs of both system efficiency  and safe remote replication with tight recovery-point and recovery-time  objectives. Using experiments conducted on a commercial replication system  and on a Linux file system we show that (i) unlike synchronous  replication, asynchronous replication is relatively insensitive to network  latency, and (ii) applications such as databases already intelligently  deal with the weak persistency semantics offered by modern file systems. Our proposed system attempts to use asynchronous replication whenever possible and uses application/file-system ?signals? to maintain synchrony between the  primary and secondary sites. We present a high-level design of our system and discuss several potential challenges that need to  be addressed in such a system. }},
