Abstract: In one example, a method can be performed that involves receiving a backup request specifying: one or more files to be backed up; a group of one or more categories, each of which corresponds to a respective range of file sizes; and, one or more storage destinations, categorizing each of the files by assigning a respective category to each file, initiating a respective backup datastream corresponding to each category that has been assigned, and requesting that each backup datastream be backed up at the respective storage destination that corresponds to the assigned category associated with that backup datastream.

Abstract: Backup failures are categorized by storing a keywords file including a set of entries, where each entry includes at least one of a keyword or string pattern corresponding to a problem that may occur during a backup provided by a backup provider for a customer, and an indication of the problem as being one of chargeable or non-chargeable to the backup provider. A log file including messages logged during the backup is read. The messages in the log file are compared against the set of entries in the keywords file to identify any problems that may have occurred during the backup. Upon a particular problem being identified, a determination is made from the keywords file whether the particular problem is chargeable or non-chargeable to the backup provider. A results file is created listing the particular problem, and whether the particular problem is chargeable or non-chargeable to the backup provider.

Abstract: Parallel restoration of a virtual machine's virtual machine disks is described. A system identifies restoration parameters for restoring multiple virtual machine disks associated with a virtual machine. The system identifies multiple available threads in an image proxy appliance that are sufficient for parallel restoration of each of the multiple virtual machine disks. Each of the multiple available threads restores a corresponding virtual machine disk as a corresponding dummy virtual machine, based on the restoration parameters. The system attaches the multiple dummy virtual machines to the virtual machine as the multiple virtual machine disks.
