Abstract: A system and method for maximizing network throughput by dynamically tuning the number of connections used during data transfer with various cloud providers. This adaptive tuning of the network connections is based on the accepted request rate for the cloud provider, the outstanding transfer capacity of the cloud network as derived from the network bandwidth, and errors and retry requests from the network and the cloud provider.

Abstract: A computer-implemented method for storing backup data includes receiving, by a computing system, data associated with a file to be backed up; performing, by the computing system, de-duplication on the file to remove duplicated data and to generate unique backup data; receiving, by the computing system, a file handle based on opening a block-based storage file; storing, by the computing system, a metadata container in the block-based storage file stripe aligned; and storing, by the computing system, a data container in the block-based storage file stripe aligned, wherein the metadata container and the data container are associated with a set of objects, and wherein the data container includes the unique backup data.

Abstract: A method for data replication between two file systems is disclosed. A base file relationship between the current generation of files and the last replicated generation may be constructed based on the generation-to-generation base file relationships of the intervening generations. The base file relationship between the current generation of files and the last replicated generation may be utilized in the replication of the current generation of files to the replica file system to reduce the amount of data that needs to be transferred while the files on the replica file system are more than one generation behind the current generation due to network outage or other issues.

Abstract: A data management device includes a persistent storage and a processor. The persistent storage includes an object storage. The processor segments a file into file segments. The processor generates meta-data of the file segments. The processor stores a portion of the file segments in a data object of the object storage. The processor stores a portion of the meta-data of the file segments in a meta-data object of the object storage.

Abstract: A method and mechanism for managing a time-indexed block map in a file system configured to store multiple versions of file data. A file system includes inodes or other structures corresponding to files in the system. Responsive to creating a file, one or more blocks are allocated for use in storing the file data. A block map is maintained for the file and is updated to include an identification of the blocks storing the file data and a timestamp corresponding to the stored data. In response to creating a file, data corresponding block map is maintained. In addition, a new entry is created in the block map which identifies the newly allocated blocks. Further, an entry of the block map is updated to (i) identify the particular blocks to which the write was directed and (ii) include a timestamp corresponding to the time of the write.

Abstract: An operating system includes a non-preemptive microkernel executing one or more processes in accordance with a predetermined priority; and one or more kernels adapted to be executed as one or more processes by the non-preemptive microkernel.

Abstract: An apparatus and a method manage data stored on one or more data storage devices using an adaptive file system by characterizing the data on the data storage devices managed by the file system; and tuning the file system by selecting one or more options to configure a kernel during boot-up and an operating system during mount time.
