File-based backups (FBB) traverse through the entire directory structure of the file system to backup all the files in each directory of the file system. FBBs can provide additional capabilities such as exclusion. These backups take longer to complete when compared to block-based backups. The File System Agent performs a FBB of the protected assets when an exclusion filter is applied to a protection policy.
Note: Exclusion filters cannot be applied to self-service protection policies and to backups taken through self-service CLI.
