Abstract
Systems and methods for replicating a client data set on a computer includes replicating the client data set using an application software on the computer; generating a manifest of a target data set during replication containing state of target data reflecting post-update state; and determining differences between the local data and manifest to determine required backup operations.
Claims40
A method for replicating a client data set on a computer, comprising:
- replicating the client data set using an application software on the computer;
- generating a manifest of a target data set during replication containing state of target data reflecting post-update state;
- and
- determining differences between the local data and manifest to determine required backup operations.
1 more element
A system, comprising:
- a plurality of customer computers to be backed-up, each customer computer running a client software to transfer back-up data files by managing replication of the client data set with an application software on the computer;
- generating a local manifest of the client data set during a replication;
- storing the local manifest on a remote server along with a server data set corresponding to the client data set;
- subsequently updating the local manifest for all write operations directed at the client data set;
- receiving back up or replication job request;
- and using the local manifest in place of the manifest on the remote server to determine files for copying to the server data set;
- a system management platform coupled to the client software over the Internet, the system management platform receiving inputs from a web user portal to control operations of the client software and the system management platform to back up the customer computer;
- and
- two or more data storage silos, each including:
- a plurality of storage directors communicating with the client software;
- and
- a clustered data storage array.
