Bacula is a true free self-hosted open source (GPL) backup framework with thousands of features to better suit your business.
The main difference between the Community and and Enterprise versions is the easiness of doing backups of specific property applications that may require more complex copying routines. While in Bacula Community we help your team eventually developing pre/post backup job scripts to run those routines, with Bacula Enterprise there are several plugins that connects directly to your applications, out of the box.
For Bacula Community we do in-company/remote training, deploy and support. Ascend to our Training & Deploy hotsite in order to fetch more information or hire us.
With Bacula Enterprise you have full support of the developer and the ability to request features, plugins to ease the backup of Oracle, MS Sql, MS Exchange, Vmware, Xen, MySQL, PostgreSQL etc., fully centered graphical configuration, management and monitoring interface, and lots of other nice features. The new S3 Cloud plugin allows seamless backup storage.
With Bacula Enterprise you won't have vendor lock-in, since we use open standards. It's also more inexpensive than other property backup software.
We don't limit backup data size or number of processors used, just the maximum number of clients your company use. If you reach that limit you can just upgrade nicely to the next subscription level at the next contract renovation. No miss-prediction worries.
