Content, Filters, and Regular Expressions - Best Practices

Applying Filters

File extensions used are unique to a software application, however, this is not guaranteed. As such, there can be conflict with other applications or your file naming policy and retention requirements.

Before applying any filter, make sure the path and scope of the filter is correct.

After applying any filters, a thorough review of backup content is recommended to confirm that essential files are not being excluded from protection.

It is recommend that you check with your recovery administrator and operating system/application vendor for the most current information.

The filters listed below, along with the specified file location, are the default filters recommended by the various software vendors. These recommendations should be evaluated on a system by system basis to ensure that necessary files are not inadvertently excluded.
