Installing the Deduplication Licenses
The deduplication feature is a licensed option. The number of deduplication licenses must match or
exceed the number of capacity licenses (based on LTU) on the VLS device. See “Installing Additional
Licenses” on page 45 for installation instructions.
After installing the required deduplication licenses, the VLS automatically reboots. When the system
is back up, it first checks the standard capacity licenses and then the deduplication licenses. Once
the deduplication licenses are verified, the deduplication feature is automatically enabled for all
supported backup types.
No further setup is required. When the next backup begins, the deduplication process begins mapping
the content of that backup. After the second backup, the system delta-differences (compares) the two
backups and the deduplication proceeds.
You may choose to disable some backup types; see “Configuring Deduplication Options” on page
93 for details.
Configuring Deduplication Options
You can include or exclude specific backups or types of backup (e.g., server type) from the
deduplication process and choose the deduplication algorithm used.

These options are not available until you have installed the appropriate number of deduplication
licenses.
