Methods, devices and computer program products facilitate the storage, access and management of log files that are associated with particular client devices. The log files provide a record of user or client device activities that are periodically sent to a data backup center. A dedicated log file server facilitates the processing and storage of an increasingly large number of log files that are generated by new and existing client devices. A storage server pre-processes the received log files to facilitate the processing and storage of the log files by the log file server. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Log file management

Systems and methods for reading data are provided herein using a data archive architecture controlled by a head server. The head server can read data in a contiguous manner across multiple storage devices for data that has been partitioned into multiple portions and spread across the multiple storage devices. Portions of a first object can be transmitted and read from a first subset of storage devices and portions of a second object can be transmitted and read from a second subset of storage devices. The head server can increment a read pointer based on a length of the portions of the first object to a determine a read location of different portions of the first object or the second object. The head server can identify different read location to read sub sequent of different portions of multiple objects using one or more lengths of the objects or portions of the object.

Systems and methods and systems for reading data sequentially on a media

Systems and methods for storing data are provided herein using a data archive architecture controlled by a head server. The head server can write data in a contiguous manner across multiple storage devices by partitioning objects into multiple portions and spreading the portions across the multiple storage devices. Portions of a first object can be transmitted to a first subset of storage devices and portions of a second object can be transmitted to a second subset of storage devices. The first subset of storage devices can write the portions of the first object to a first write location indicated by a write pointer. The head server can increment the write pointer based on a length of the portions of the first object to a second write location. The second subset of storage devices can write the portions of the second object to the second write location.

Methods and systems for storing data sequentially on a media

A method of storing a file in memory so that the file can be recovered in the event of a memory failure is provided. A block of memory having a first predetermined memory size is allocated at a first device. A first header is defined that includes an identifier of a first file and a sequence value. The defined first header is written to the allocated block of memory, and a first cluster of the first file is written to the allocated block of memory. The first cluster has a second memory size that is smaller than the first predetermined memory size. The sequence value is updated, and a next cluster of the first file is identified. The process is repeated with the next cluster as the first cluster and with the updated sequence value as the sequence value until the first file has been written to the allocated block of memory.
