Systems and methods for adaptively selecting file-recall modes

摘要

A computer-implemented method for selecting file-recall modes based on environmental properties may include: 1) identifying a request to recall a file from a secondary storage system to a primary storage system, 2) identifying at least one environmental property associated with the file, 3) selecting, based at least in part on the identified environmental property, a recall mode for recalling the file, and then 4) recalling the file from the secondary storage system to the primary storage system using the selected recall mode. Various additional methods, systems, and configured computer-readable-storage media are also disclosed.

1. A computer-implemented method for adaptively selecting file-recall modes, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:
intercepting a request to recall a file from a secondary storage system to a primary storage system; after intercepting the request:
identifying the current value of at least one dynamic environmental property associated with the file that may negatively impact performance of at least one mode of recalling the file from the secondary storage system to the primary storage system by negatively impacting at least one of:
load on the primary storage system;load on the secondary storage system;network load on a network through which the file will be recalled;identifying at least one policy that comprises criteria for selecting, from among a plurality of different recall modes based on the current value of the dynamic environmental property, an appropriate recall mode for recalling the file from the secondary storage system to the primary storage system, the plurality of different recall modes comprising at least two of:
a full recall mode;a partial recall mode;a pass-through recall mode;adaptively selecting, at least in part by applying the policy to the current value of the dynamic environmental property identified after intercepting the request, a recall mode for recalling the file from the secondary storage system to the primary storage system;recalling the file from the secondary storage system to the primary storage system using the selected recall mode.
