Licensing Requirements for Deduplication

No additional license is required to perform data deduplication because functionality is built into the Arcserve Backup base product. However, you should consider the following:

• Deduplication devices can be used in disk to disk to tape or disk to tape to tape (staging) operations. However, to use the staging feature with more than two streams of backup data, you must license the Arcserve Backup Enterprise Module.
• For deduplication, you should upgrade your Windows, UNIX, Linux, and MAC client agents to Arcserve Backup r12.5 or later.
• To back up deduplication device files, you must license the Arcserve Backup Agent for Open Files. On Windows 2003, 2008, and 2012 systems, only the license for the Agent for Open Files is required; the Agent does not need to be installed.
