Abstract: A computer-implemented method for email journaling may include (1) maintaining, by a journaling mail server, a cache that associates together an update sequence number that indicates a version of an email distribution list and email addresses that are both designated as targets for journaling and included within the version of the email distribution list identified by the update sequence number, (2) receiving, by the server, an email that includes, within at least one header field, a candidate update sequence number and an email distribution list identifier, (3) determining that the update sequence number in the cache is a match for the candidate update sequence number in the header field, and (4) identifying, based on the match between the update sequence number and the candidate update sequence number, the email addresses specified in the cache as the targets for journaling. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for selecting file-recall modes based on environmental properties may include (1) intercepting a request to recall a file from a secondary storage system to a primary storage system, (2) identifying a value of a dynamic environmental property associated with the file that may negatively impact performance of a mode of recalling the file from the secondary storage system to the primary storage system, (3) identifying a policy that comprises criteria for selecting an appropriate recall mode for recalling the file from the secondary storage system to the primary storage system, (4) adaptively selecting, by applying the policy to the value of the dynamic environmental property, a recall mode for recalling the file, and (5) 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.

Abstract: 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.
