Avamar Downloader Service
The Avamar Downloader Service is a file distribution system that delivers software
installation packages to target Avamar systems. The distribution process uses minimal
bandwidth by downloading only files that you request through the Avamar Installation
Manager.
The Avamar Downloader Service uses a local file cache to ensure that a file is fetched
only once from the EMC repository, no matter how many times an Avamar system
requests the file. You can remove old files from the local repository to free disk space.
