As you are probably aware, the community Windows File daemon binaries are no longer produced by the Bacula project. Consequently, as a service to the community, Bacula Systems is offering its Windows Enterprise binaries at a price that is designed to simply cover the costs to produce and distribute those binaries. These Enterprise Windows binaries are compatible with the community Director and Storage daemon. However, please note, that the Windows Storage daemon and Director binaries are not provided. Included in this package is an installer for both 32 and 64 bit machines. Support is not offered by Bacula Systems, but is available through the Community Bugs database.

In purchasing a license, by following the link below, you will be able to download your Bacula Enterprise Windows binaries (32/64) for a period of 6 months. During this time, if there are additional releases, you may also download them. The license gives you the right to use the downloaded Bacula Enterprise binaries with the Bacula community version. This is a one time license fee that allows you to continue using the downloaded binaries for as long as you respect the terms of the license. After the 6 month download period, if you want an updated Bacula Enterprise version, you will need to purchase a new license.
