Bareos has already presented the release candidate for the new version 17.2 at Open Source Backup Conference in Cologne, Germany in Sept. 2017. The final release was officially published in January 2018.
There are many new features in the web UI as well as under the hood. Most new features were sponsored by customers.
Especially professional users with large environments will benefit from the new database optimization (de-normalization of the file table), which leads to significant speed-increase when backing up millions or more files. Thanks to Cartika for sponsoring.
An enterprise from the media industry has sponsored the enhancements regarding backups in storage are networks using the NDMP protocol. Bareos is now capable of using the NDMP 2-way backup, which offers the possibility to directly transfer files from the storage to a tape library over the storage area network. Furthermore single-file-restore via NDMP is now much faster thanks to the implementation of the Direct Recovery features (DAR and DDAR).
User with distributed networks, such as hosters backing up systems from customer networks, will benefit from the LanAddress feature. These customers can now perform central and / or decentral backups of clients. If both client and storage daemon have an optional LanAddress configured, the client will write the data directly to the local storage (also sponsored by Cartika).
The webui now offers a progress bar for each running job and opens the possibility to individually run customized jobs with arbitrary options set. New to the GUI are the languages Slovak, Turkish, Czech, which sums up to 11 supported languages.
A national archive has sponsored the development of an S3 compatible interface. Users can now write and read their backup data into any Amazon S3 compatuble storage.
Installation packages for all major Linux distributions as well as Windows and MacOS are available for download. Following packages with updates and patches for this release will be available for subscription customers, only.
The front-end is now multi-lingual: users can choose at login between English, German, French and Russian. Further translation projects have already been started by the community. The clients’ list now shows, if there are updates of the Bareos software available for each client. Also new is the handling of autochangers within the GUI: used drives and tapes are shown, tapes can be labled and im / exported.
With 16.2 the multi-tenancy implementation was completed by filling some long standing gaps in the ACL implementation. Users can now only see and restore data to the client(s), they are allowed to regarding the defined rules and roles. This development was particularly sponsored by customers from the ISP industry.
Also supported by an ISP is the development of the “Client Initiated Connection” feature. If enabled, all connections between a backup client and the Bareos servers are initiated from the client. This way laptops can connect from different network segments in an enterprise network. Servers on premise can connect to Bareos backup servers at external sites, without the need to grant access to the internal network from outside service providers.
The new feature “Always Incremental” is interesting especially for users with big data: time- and network-capacity consuming full-backups only have to be taken once. Sub-sequent backup jobs can only transmit changed files incrementally to the backup servers forever. The new way of merging the existing incremental backups on the server, reduces the number of necessary synthetic full-backups on the server. This means an enormous reduction of needed CPU-time and storage space on the server but still with improved restore times.
The new release also comes with a new directory structure for configuration files, which is optimized for configuration provisioning and the base for the new configuration API. Using the API or the command console, for example clients can be created and the according configuration files are automatically generated by Bareos and saved to the right directory.
The new MySQL plugin offers the possibility to make hot-backups of MySQL / MariaDB databases with Bareos, as well as point-in-time recovery of databases.
Our 15.2 release candidate has passed all regression and continuous integration tests on all supported platforms. Repositories are avialable here: http://download.bareos.org/bareos/release/15.2/
We are looking forward for your feedback and bugreports, in order to help us to publish a broadly tested 15.2 major release soon.

For a full list of new features, see README.md in GIT, all news for versions from 13.x until 14.2.x are relevant for this new release. You'll find installation packages here: http://download.bareos.org/bareos/release/14.2/
Bareos 13.2.2 has been the second stable release. Here are some highlights:
- Passive clients: to ease access to backup clients in separated network segments (like DMZs), a client can be defined 'passive', which means all needed backup connections (from director and storage daemon (SD)), will be initiated from the servers. Hence, no connection initiation from the DMZ into the internal network is needed to backup a DMZ client anymore. To be able to use that feature, you need to set
compatible = no
in order to make this option available.
- Backup to disk to cloud: with the new SD to SD communication you can do copy or migration jobs to other SDs, which might be located at any other location
- The status scheduler command now shows a preview of upcoming scheduled jobs for a given time range. This lets an backup admin verify the scheduler configuration easily
- Fastzlib used as alternative to speed up compression

Bareos 12.4 was the first stable release. These are the changes compared to Bacula 5.2
