INTELLIGENT PROTECTION OF OFF-LINE MAIL DATA

摘要

A system according to certain aspects improves the process of creating secondary copies of data (e.g., creating backup copies). The system can compute the score of the data (e.g., a computer file storing information) to be backed up, and determine whether the score satisfies one or more threshold criteria before backing up the data. In one example, a change in score indicates a change in the content of the data. The threshold criteria may be that the score be different from the score of the most recently backed up copy of the data.

主权项

1. A method for protecting mail data, the method comprising:
with a client computing device comprising computer hardware, processing a mail data file stored in one or more primary storage devices in preparation for creation of a secondary copy of the mail data file in one or more secondary storage devices, the mail data file containing a plurality of mail objects; with one or more computing devices comprising computer hardware,
creating a first secondary copy of the mail data file on the one or more secondary storage devices;determining a first score associated with the mail data file as it existed as of the creation of the first secondary copy;in response to determining that the mail data file has been modified since the creation of the first secondary copy, calculating a second score based on the mail data file as it existed following the modification;comparing the second score with the first score; anddetermining whether a result of the comparison satisfies one or more threshold criteria, wherein a second secondary copy of the mail data file is created on the one or more secondary storage devices in response to determining that the result of the comparison satisfies the one or more threshold criteria.
