Patent ID: 8554727

Claim:
A method, comprising: modeling dataflow between at least one module of a tier of a multi-tier network and at least one module of another tier of the multi-tier network, the tier and the another tier of the multi-tier network being at different geographical locations; solely marking, in accordance with the model, an instance of a transaction event based on an event data and a time of a backup operation of data associated with the multi-tier network, the event data being at least one of a system crash, a login failure and a configuration change; quiescing, in accordance with the model, at least one of the at least one module of the tier and the at least one module of the another tier of the multi tier network associated with at least one of the event data and the time of the backup operation based on the marking, the quiescing including determining a sequence of temporary disablement of the at least one of the at least one module of the tier and the at least one module of the another tier; coordinating, in accordance with the model, with a continuous data protection module of the multi-tier network to perform the backup operation at one of a file level and a block level to ensure data integrity in the multi-tier network consistent with the event data and the time of the backup operation; and coalescing, in accordance with the model, a set of data at intervals adjacent to an event on whose occurrence the backup operation is based, wherein the coalescing is based on a policy data.
