Identifying file exclusions for write filter overlays
A system and method for identifying write filter exclusions for information handling systems in a computing environment. Each information handling system includes a file exclusion driver and a file exclusion service. The file exclusion driver can monitor files to be stored in a write filter overlay and identify recurring files previously stored in the write filter overlay. The file exclusion driver can determine if a cumulative file size of a recurring file exceeds an adjustable threshold, and add data describing the recurring file to an exclusion list if the cumulative file size exceeds the adjustable threshold. The file exclusion service can transmit the exclusion list to the device management server for analysis, receive a master exclusion list from the device management server based on analysis, and can store a set of excluded files in a local storage resource based on the master exclusion list.

one or more excluded files included in a threshold percentage of the plurality of exclusion lists;
one or more excluded files having a highest frequency of being previously stored in the write filter overlay of each information handling system; and
one or more excluded files having a highest cumulative file size.
4. The system of claim 1 , wherein the file exclusion driver is further configured to:
identify one or more large files of the plurality of files, each of the one or more large files associated with a file size that exceeds the adjustable threshold; and
add data describing the one or more large files to the exclusion list.
5. The system of claim 1 , wherein the file exclusion driver is further configured to:
identify one or more folders storing the one or more recurring files on the information handling system; and
add data describing the one or more folders to the exclusion list.
6. The system of claim 1 , wherein the cumulative file size is comprised of a file size for each instance in which the recurring file was previously stored in the write filter overlay.
7. The system of claim 1 , wherein the one or more recurring files include at least one of:
a plurality of log files;
a plurality of browser cache files; and
a plurality of application cache files.
8. A method for identifying write filter exclusions in a computing environment, the method comprising:
monitoring, by an information handling system, a plurality of files to be stored in a write filter overlay of the information handling system;
identifying one or more recurring files of the plurality of files, each of the one or more recurring files previously stored in the write filter overlay, and each of the one or more recurring files associated with a cumulative file size;
determining if the cumulative file size associated with each of the one or more recurring files exceeds an adjustable threshold;
in response to determining that a cumulative file size associated with a recurring file of the one or more recurring files exceeds the adjustable threshold, adding data describing the recurring file to an exclusion list;
transmitting the exclusion list to a device management server for analysis;
receiving a master exclusion list from the device management server based on the analysis, the master exclusion list including data describing a set of excluded files to be stored in a local storage resource of the information handling system;
redirecting the set of excluded files from being stored in the write filter overlay of the information handling system via an application programming interface; and
storing the set of excluded files into the local storage resource of the information handling system.
9. The method of claim 8 , wherein the analysis comprises:
receiving, by the device management server, a plurality of exclusion lists, each exclusion list including data describing one or more excluded files, and each exclusion list transmitted by an information handling system in the computing environment;
selecting, by the device management server, the set of excluded files from the plurality of exclusion lists;
generating, by the device management server, the master exclusion list; and
transmitting, by the device management server, the master exclusion list to each information handling system in the computing environment.
10. The method of claim 9 , wherein the set of excluded files comprises at least one of:
one or more excluded files included in a threshold percentage of the plurality of exclusion lists;
one or more excluded files having a highest frequency of being previously stored in the write filter overlay of each information handling system; and
one or more excluded files having a highest cumulative file size.
11. The method of claim 8 , further comprising:
identifying one or more large files of the plurality of files, each of the one or more large files associated with a file size that exceeds the adjustable threshold; and
adding data describing the one or more large files to the exclusion list.
12. The method of claim 8 , further comprising:
identifying one or more folders storing the one or more recurring files on the information handling system; and
adding data describing the one or more folders to the exclusion list.
13. The method of claim 8 , wherein the cumulative file size is comprised of a file size for each instance in which the recurring file was previously stored in the write filter overlay.
14. The method of claim 8 , wherein the one or more recurring files include at least one of:
a plurality of log files;
a plurality of browser cache files; and
a plurality of application cache files.
15. A method for identifying write filter exclusions for a plurality of information handling systems in a computing environment, the method comprising:
receiving, by a device management server, a plurality of exclusion lists, each exclusion list including data describing one or more excluded files, and each exclusion list transmitted by an information handling system in the computing environment;
selecting, by the device management server, a set of excluded files from the plurality of exclusion lists, the set of excluded files to be stored in a local storage resource in each of the plurality of information handling systems in the computing environment;
generating, by the device management server, a master exclusion list, wherein the master exclusion list includes the set of excluded files;
