Abstract: Disclosed are systems, methods and computer readable mediums for optimized throughput of an object based storage system. The systems, methods and computer readable mediums including receiving an I/O request to the storage system, determining a busy ratio based on a number of blocks available in a local cache and a queue size, determining an I/O speed to the storage system, the I/O speed based at least in part on the busy ratio and an upload speed, wherein the I/O speed does not exceed a current speed of the storage system, and executing the I/O request to the storage system at the I/O speed.

Abstract: A method for generating a synthetic backup comprises generating a full backup of a data source at an initial timestamp and generating a first incremental backup of the data source at a first timestamp subsequent to the initial timestamp. The first incremental backup comprises one or more modifications made to data stored in the data source between the initial timestamp and the first timestamp. A synthetic backup is generated from at least the full backup and the first incremental backup by altering one or more file system parameters of the data source and performing forwards reads for the first incremental backup based on the modified file system parameters. In response to determining that forward read data has not been merged into a synthetic backup, the forward read data is stored in a read cache and the full backup is merged with the forward read data in the read cache.
