Updating and upgrading Bareos
=============================

.. index::
   pair: Bareos; Update

Bareos consists of 4 main components:

  * |dir|
  * |sd|
  * |fd|
  * |webui|


.. _section-UpdateUpgradePreamble:

Before updating or upgrading Bareos software
--------------------------------------------

.. index::
   single: Update Preamble

We consider both operations usually safe and they can be applied without restriction to all installations. The Bareos project avoids breaking changes as far as possible, so usually existing configurations will work with newer installations without changes.
Especially when updating the |dir| (together with the corresponding |sd|) it is recommended to do a number of security steps before going ahead:

- Read the :ref:`Bareos current release notes <bareos-current-releasenotes>` and watch out for changes that might impact your installation. Take special care for the :strong:`Breaking Changes` paragraph, as it contains the information about changes that require your special attention when upgrading your installation as they might require adaptions of the configuration.
- Update your operating system to the latest security and patch level of the publisher.
- Empty the running jobs queue.
- Run :strong:`BackupCatalog` or equivalent as last job (keep the most up to date database dump & configuration state).
- Stop all Bareos daemons.
- If not done before

   - Save a copy of the actual configuration used. (Usually :file:`/etc/bareos/` and :file:`/etc/bareos-webui/`.
   - Dump your database content to an easy to restore format.

- Cleanup the working dir :file:`/var/lib/bareos`

   - Remove any old crash traces :file:`*.bactrace` and :file:`*.traceback` files.
   - Remove any left debugging :file:`*.trace` files.
   - Remove any leftover :file:`*.mail` that have not been sent.
   - Remove any :file:`*core*` that are left behind.

- Rotate log files if you don't use :command:`logrotate`

   - :file:`/var/log/bareos/bareos.log`
   - :file:`/var/log/bareos/bareos-audit.log`

Now you can safely apply the update or upgrade.

.. warning::

   Please remind, that |dir| and |sd| must always have the same version.
   The version of the |fd| may differ.


.. note::

   When you change the repository and refresh it, it is likely to have a new signing key.
   You will have to accept it.

         Note: Signing data enables the recipient to verify that no modifications occurred after the data
         were signed. Accepting data with no, wrong or unknown signature can lead to a corrupted system
         and in extreme cases even to a system compromise.

         Note: A GPG pubkey is clearly identified by its fingerprint. Do not rely on the key's name. If
         you are not sure whether the presented key is authentic, ask the repository provider or check
         their web site. Many providers maintain a web page showing the fingerprints of the GPG keys they
         are using.

.. _section-UpdateFromCommunityToSubscription:

Updating from community to subscription binaries
------------------------------------------------

.. index::
    single: update from community to subscription
    pair: Bareos; community repository
    pair: Bareos; subscription repository

To update the installed community packages (https://download.bareos.org) to Bareos Subscription packages,
you will have to point to the subscription repositories located at https://download.bareos.com/.

Once you received your `download.bareos.com` portal/repository credentials, you can refer to the following section :ref:`section-AddSoftwareRepository` for complete instructions how-to use the :file:`add_bareos_repositories.sh` helper.

Choose the same operating system and Bareos major version you are already using.

Read the :ref:`Bareos current release notes <bareos-current-releasenotes>` to check all fixes that have been made.

Proceed to the next section, to install last minor bugfix release on your systems.


.. _section-UpdateMinorBugfix:

Updating Bareos to the latest minor or bugfix release
------------------------------------------------------

.. index::
   single: Update latest minor bugfix
   pair: update; minor;
   pair: update; bugfix

In most cases, a Bareos update is simply done by a package update of the distribution.

.. note::

   Please before processing, apply steps in :ref:`section-UpdateUpgradePreamble`


In this section, we explain how to update your Bareos major version to the latest minor or bugfix release.

For upgrading to a new major version see :ref:`Update Bareos to a new major release <section-UpgradeMajor>`.

.. note::

   You can install directly the latest Major,Minor,Bugfix release available.
   So updating from 21.0.0 directly to 21.1.5 is not a problem.



Example how to update from 21.0.0 to 21.1.5.

.. _section-UpdatePostChecks:

Post update checks
~~~~~~~~~~~~~~~~~~

.. index::
   single: Update post checks

After the update, it is recommended to check if any new warnings are raised when starting the daemon, mostly deprecated configuration directives.
Bareos will mark configuration directives at least for one major release as deprecated, before removing them.

To do so you can use the `-t` flag:

.. code-block:: shell-session
   :caption: Shell example to check the Bareos configuration

   root@host:~# bareos-fd -t
   root@host:~# su - bareos -s /bin/sh -c "bareos-sd -t"
   root@host:~# su - bareos -s /bin/sh -c "bareos-dir -t"
   There are configuration warnings:
    * using deprecated keyword CollectStatistics on line 8 of file /etc/bareos/bareos-dir.d/storage/File.conf

The same warnings are also shown on a regular start of the daemons.


Depending of the operating system and its configuration, you will have to restart the daemons.
Use your operating system command to do so.


.. code-block:: shell-session
   :caption: Shell command to restart all bareos daemon with systemd on Linux

   root@host:~# systemctl restart bareos-director bareos-storage bareos-filedaemon
   root@host:~# systemctl status bareos-director bareos-storage bareos-filedaemon

.. _section-UpgradeMajor:

Upgrading Bareos to a new major release
---------------------------------------

.. index::
   single: Upgrade latest major version
   pair: Bareos; Upgrade
   pair: Upgrade; Major

In most cases, a Bareos major upgrade can be achieved by:

- Add new major repository (subscription only)
- Package upgrade of the distribution.
- Database schema upgrade with helper scripts (if schema was changed).
- Configuration review to cleanup deprecated or removed parameters.
- Review of home made scripts and manage their adaptation in case of changes.

It is generally sufficient to upgrade directly to the latest release, without having to install any intermediate releases.
However, it is required to read the release notes of all intermediate releases.

One exception is when using a |mysql| Bareos catalog,
which have been removed with Bareos :sinceVersion:`21.0.0: MySQL backend removed`.
Therefore you first have to upgrade to Bareos 20 and migrate the |mysql| into a |postgresql| Bareos Catalog, see :ref:`section-MigrationMysqlToPostgresql`.


Prepare the upgrade
~~~~~~~~~~~~~~~~~~~

If you not have already done those steps, please refer to instructions in :ref:`section-UpdateUpgradePreamble`.

.. warning::

   If you use any third party plugins, you should check and test their functionalities with the new major version beforehand.

.. _sectionUgradeMajorRepository:

Upgrade the Bareos download repositories
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This does only apply for subscription repositories (https://download.bareos.com/bareos/release/).
The community repository (https://download.bareos.org/current/) will always contain the latest build of the most recent stable branch.

- First remove the existing Bareos repository definitions, by either removing the definition file(s) or by using your package manager.
- Point your browser to the new Bareos major version for your operating system on the download server.
- Open or save the helper script :file:`add_bareos_repositories.sh`.

  - You can refer to the following section :ref:`section-AddSoftwareRepository` for complete instructions how to use the :file:`add_bareos_repositories.sh` helper.

- Transfer the file to your Bareos server, and execute it as **root**.
  This will create (or depending on your OS update) the Bareos repository information.

.. code-block:: shell-session
   :caption: Shell command to upgrade the Bareos repository

   root@host:~# sh add_bareos_repositories.sh

You should be able now to proceed the appropriate commands to refresh the packages list and upgrade the package to the newer version.

.. note::

   You can refer to section :ref:`section-UpdateMinorBugfix` for commands example.


.. _sectionUpdateConfigurationFiles:

Updating the configuration files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When updating Bareos through the distribution packaging mechanism,
the existing configuration files are kept as they are.

If your configuration didn't show any deprecation warnings prior the upgrade, no configuration change will be required on upgrades.
Check the :ref:`Release Notes <releasenotes>` for breaking changes or other special cases.


.. _sectionUpdateDatabaseScheme:

Updating the database scheme
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sometimes improvements in Bareos make it necessary to update the database scheme.


.. warning::

   If the Bareos catalog database does not have the current schema, the Bareos Director refuses to start.


.. code-block:: shell-session
   :caption: Shell example of bareos-dir failing to start due to lack of database schema update

   root@host:~# su - bareos -s /bin/sh -c "bareos-dir -t"
   bareos-dir: dird/check_catalog.cc:64-0 Could not open Catalog "MyCatalog", database "bareos".
   bareos-dir: dird/check_catalog.cc:71-0 Version error for database "bareos". Wanted 2210, got 2192
   bareos-dir ERROR TERMINATION
   Please correct the configuration in /etc/bareos/bareos-dir.d/*/*.conf


Detailed information can then be found in the log file :file:`/var/log/bareos/bareos.log`.

Take a look into the :ref:`Release Notes <releasenotes>` to see which Bareos updates do require a database scheme update.


.. warning::

   Especially the upgrade to Bareos >= 17.2.0 restructures the **File** database table.
   In larger installations this is very time consuming (up to several hours or days)
   and temporarily doubles the amount of required database disk space.


.. _section-UpdateDatabaseDebianDistributions:

Debian based Linux Distributions
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Since Bareos :sinceVersion:`14.2.0: dbconfig-common (Debian)` the Debian (and Ubuntu) based packages support the **dbconfig-common** mechanism to create and update the Bareos database. If this is properly configured, the database schema will be automatically adapted by the Bareos packages.

For details see :ref:`section-dbconfig`.

If you disabled the usage of **dbconfig-common**, follow the instructions for :ref:`section-UpdateDatabaseOtherPlatforms`.


.. _section-UpdateDatabaseOtherPlatforms:

Other Platforms
^^^^^^^^^^^^^^^

This has to be done as database administrator.
On most platforms Bareos knows only about the credentials to access the Bareos database, but not about the database administrator credentials to modify the database schema.

The task of updating the database schema is done by the scripts :command:`/usr/lib/bareos/scripts/update_bareos_tables` and :command:`/usr/lib/bareos/scripts/grant_bareos_privileges`.

However, this script requires administration access to the database. Depending on your distribution, this requires different preparations.

More details can be found in chapter :ref:`Catalog Maintenance <CatMaintenanceChapter>`.

.. code-block:: shell-session
   :caption: Update PostgreSQL database schema on most Linux distribution

   su postgres -c /usr/lib/bareos/scripts/update_bareos_tables
   su postgres -c /usr/lib/bareos/scripts/grant_bareos_privileges

The :command:`grant_bareos_privileges` command is required, if new databases tables are introduced. It does not hurt to run it multiple times.

After this, restart the Bareos Director and verify it starts without problems.
