Systems and methods for managing file backup

A system for managing file backup, the system comprising:

• a detection module, stored in memory, that detects, by a computing device, an attempt to upload a file to a backup storage;
• a calculation module, stored in memory, that calculates a degree of difference indicating changes between the file and a previous version of the file on the backup storage;
• a comparison module, stored in memory, that compares, by the computing device, a list of acceptable software applications for the file with a list of software applications that have made the changes to the file, wherein the computing device tracks each software application that writes to the file by adding previously undetected software applications to the list of software applications that have made the changes to the file;
• a change module, stored in memory, that calculates a change score for the file that indicates a likelihood of corruption in the file, wherein the change score is based on:
• the degree of difference;
• and
• the comparison of the list of software applications that have made the changes with the list of acceptable software applications;
• a backup module, stored in memory, that applies, based on the likelihood of corruption in the file indicated by the change score, a backup policy to the attempt to upload the file, wherein the backup policy sets a time-to-live period for the previous version of the file;
• and
• at least one processor that executes the detection module, the calculation module, the comparison module, the change module, and the backup module.

A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• detect, by the computing device, an attempt to upload a file to a backup storage;
• calculate a degree of difference indicating changes between the file and a previous version of the file on the backup storage;
• compare, by the computing device, a list of acceptable software applications for the file with a list of software applications that have made the changes to the file, wherein the computing device tracks each software application that writes to the file by adding previously undetected software applications to the list of software applications that have made the changes to the file;
• calculate a change score for the file that indicates a likelihood of corruption in the file, wherein the change score is based on:
• the degree of difference;
• and
• the comparison of the list of software applications that have made the changes with the list of acceptable software applications;
• and
• apply, based on the likelihood of corruption in the file indicated by the change score, a backup policy to the attempt to upload the file, wherein the backup policy sets a time-to-live period for the previous version of the file.
