A data system for managing synchronized data protection operations at plural nodes (410, 411, 412) of the data system; the data system including a node chain including at least a first node and a second node downstream of the first node in the node chain, and the first node being communicably connected to the second node, wherein the first node receives data from an application host; the first node being configured to operate on the basis of first sequence information including instructions of a sequence of operations to be executed by the first node for performing a first data protection operation and for synchronizing the sequence of operations to be executed by the first node with one or more sequences of at least one of one or more upstream nodes of the first node and one or more downstream nodes of the first node, the first node being configured to perform the first data protection operation and to transmit a synchronization notification to the second node on the basis of respective instructions included in the first sequence information; and wherein the second node is configured to receive the synchronization notification from the first node and to operate on the basis of second sequence information including instructions of a sequence of operations to be executed by the second node for performing a second data protection operation and for synchronizing the sequence of operations to be executed by the second node with one or more sequences of at least one of one or more upstream nodes of the second node and one or more downstream nodes of the second node, the second node being configured to perform the second data protection operation upon receipt of the synchronization notification on the basis of a respective instruction included in the second sequence information, wherein each of the first and second data protection operations includes one or more of: a backup operation, a mirror operation, a snapshot operation, a versioning operation, an archiving operation, and a replicate operation, wherein the second node is further configured to transmit a confirmation notification to the first node when having performed the second data protection operation on the basis of a respective instructions included in the second sequence information, wherein the first and second data protection operations relate to data being associated with at least one application running on the application host; wherein the first node is configured to request to put the at least one application on hold on the basis of a respective instruction included in the first sequence information prior to performing the first data protection operation and prior to transmitting the synchronization notification to the second node, and wherein the first node is configured to request to resume the at least one application on the basis of a respective instruction included in the first sequence information upon receiving the confirmation notification from the second node, wherein the first node is configured to request, on the basis of a respective instruction included in the first sequence information and before requesting to put the at least one application on hold, application context information to the related at least one application which indicates one or more logical storage locations of data being related to the at least one application, wherein the first node is configured to request, on the basis of a respective instruction included in the first sequence information and before requesting to put the at least one application on hold, storage context information which indicates one or more physical storage locations of data being related to the at least one application being associated with the one or more logical storage locations indicated in the application context information, wherein the first node is configured to transmit, on the basis of a respective instruction included in the first sequence information and before requesting to put the at least one application on hold, the requested application context information to the second node, wherein the second node is configured to request, on the basis of a respective instruction included in the second sequence information, storage context information which indicates one or more physical storage locations of data being related to the at least one application being associated with the one or more logical storage locations indicated in the application context information; or the first node is configured to translate the received application context information into storage context information, which indicates one or more physical storage locations of data being related to the at least one application being associated with the one or more logical storage locations indicated in the application context information, on the basis of a respective instruction included in the first sequence information and on the basis of the application context information, and to transmit the generated storage context information to the second node.
