Abstract
A method according to one embodiment includes receiving a request to perform a backup of data associated with an application running on multiple servers; calculating a time value based on communications with the servers, the time value calculation including at least one of a latency of at least one of the communications, and a difference between a reference time clock value and a time clock value of at least one of the servers; and communicating with I/O Handlers on the servers for initiating a coordinated backup operation on the data at about a same start time. Additional systems, methods, and computer program products are also disclosed.
