+
+.. |date| date::
+
+The objective of TISbackup is to benefit from file backups
+and centralized alert feedback on "reasonable" data volumes
+(of the order of a few TB).
+
+TISBackup allows:
+
+* to know if a recent backup exists;
+
+* to keep a history with deduplication at the file level (no duplicate backups);
+
+* to have an immediate view of the contents of a server or a server area
+  for data restoration ;
+
+* to export the last backup to an external media in order to transfer
+  it to a secure location;
+
+* to configure the backup cycle with a simple
+  and readable :mimetype:`.ini` file;
+
+* to work with a module mechanism to extend the type of backups
+  (https, rsync, postgres, mysql,) of virtual machines;
+
+Satisfying these needs stems from the need for a tool
+to manage a vast pool of machines each hosting a multitude
+of different software or services (different editors,
+different hardware platforms and operating environments, etc.).
+Finally, as the backup procedures of a publisher changed without any warning,
+the remote backup mechanisms were regularly broken, which caused us some scares
+with the mechanisms we were using before.
+
+Overview of existing solutions
+==============================
+
+Different open source solutions exist but did not meet our specifications.
+
+Baccula
+-------
+
+:program:`Baccula` is a high-performance solution for full backups on tape
+and removable media. However, a restore can take a long time
+and the storage of a history can be voluminous.
+The backup is saved on a file system that is not readable by a Windows system.
+An uninitiated "backup manager" will not be able to check the contents
+of his backup from home.
+
+r-snapshot
+----------
+
+:program:`r-snapshot` almost corresponds to the specifications
+but is complex to configure and any necessary modification
+would have been difficult to develop as an overlay of the existing one:
+
+* the backups are organized by date then by zone which is the opposite
+  of what was desired;
+
+* it is not possible to configure different backup frequencies
+  according to the criticality levels of the servers;
+
+* finally, the deletion of obsolete backups is done in the same process
+  as the backups, which can be very long and can be problematic
+  if there is a problem during the backup.
+

+Installing and configuring TISBackup on Debian
+==============================================

+
+Setting up the GNU/Linux Debian server
+--------------------------------------
+
+In order to install a fresh Debian Linux 10 *Buster* (physical or virtual)
+without graphical interface, please refer to the
+`Debian GNU/Linux Installation Guide<https://www.debian.org/releases/buster/amd64/>`_.
+
+Configuring network parameters
++++++++++++++++++++++++++++++
+
+.. include:: wapt-resources/linux-server-naming.txt
+
+Configuring the name of the Debian server
+++++++++++++++++++++++++++++++++++++++++
+
+.. hint::
+
+  The short name of the future TISBackup server must not be longer
+  than **15 characters** (the limit is due to *sAMAccountName* restriction
+  in Active Directory).
+
+The name of the TISBackup server must be a :abbr:`FQDN (Fully Qualified Domain Name)`,
+that is to say it has both the server name and the DNS suffix.
+
+* modify the :file:`/etc/hostname` file and write the FQDN of the server;
+
+.. code-block:: bash
+
+  # /etc/hostname of the TISBackup server
+  srvbackup.mydomain.lan
+
+* configure the :file:`/etc/hosts` file, be sure to put both the FQDN
+  and the short name of the server;
+
+.. code-block:: bash
+
+  # /etc/hosts du waptserver

+
+Technical background for TISBackup
+==================================
+
+The deduplication of this solution is based on the hardlinks
+of ext3/4 file systems used for storing backup files.
+
+The backup server must run :program:`rsync` in server mode,
+and the workstations to be backed up must be equipped with :program:`rsync`
+and :program:`ssh` (usually basic on machines running GNU/Linux,
+with :program:`cygwin` (or another tool like :program:`cwrsync`)
+for machines running MS Windows).
+
+tisbackup
+---------
+
+:program:`tisbackup` is a python script that the backup server runs
+at regular intervals. The configuration file :file:`tisbackup.ini` contains
+the details of the tasks to be executed.
+
+:program:`tisbackup` has different options for its execution,
+available in the :command:`tisbackup --help` command,
+the main ones being the following:
+
+* :command:`backup`: executes all scheduled backups;
+
+* :command:`cleanup`: examines the backups and deletes those
+  that are older than the defined maximum retention time ;
+
+* :command:`checknagios`: returns the content that can be viewed by nagios ;
+
+* :command:`retryfailed`: redoes the backups that previously failed;
+
+* :command:`exportbackup`: exports the last valid backups
+  to the specified location (remote, external media, ...);
+
+* :command:`register_existing`: scans the backups that have been made
+  and adds the missing ones to the database;
+
+tisbackup.ini
+-------------
+
+:file:`tisbackup.ini` defines the backups to be executed and supervised.
+It is written with a simple formalism.
+
+The different types of backups are:
+
+* ``rsync``: the backup of a directory by rsync using the rsync protocol;
+
+* ``rsync+ssh``: the backup of a directory by rsync with the ssh protocol;
+
+* ``mysql+ssh``: saving a mysql database in a gzipped sql file,
+  with the ssh protocol;
+
+* ``pgsql+ssh``: the backup of a postgresql database in a gzipped sql file,
+  with the ssh protocol;
+
+* ``xen-xva``: the backup of a virtual machine running on an XCP server
+  as an XVA file;
+
+* ``xen-meta-data``: the backup of XCP metadata from a virtualization server;
+
+* ``switch``: the backup of switches;
+
+* ``null``: null backup of a server that does not require a backup but for which
+  it is known to be taken into account (Nagios supervision);
+
+The first part of the :file:`tisbackup.ini` file,
+starting with the ``[Global]`` tag, determines:
+
+* the path to the folder where the backups will be stored;
+
+* the maximum retention time of a backup (in days);
+
+* the maximum delay before triggering a nagios critical message (in hours);
+
+* possibly the limit of usable bandwidth;
+
+The rest of the file lists the different backups to be made,
+with specific parameters for each type of backup:
+
+* name of the directory in the backup;
+
+* backup type;
+
+* server name;
+
+* directory (in case of a directory backup);
+
+* directories to be excluded (idem);
+
+* location of the ssh key to be used (private key on the backup server);
+
+* name of the database (in case of mysql or postgresql database backup);
+
+* ssh port number to use;
+
+* database user and password (in case of mysql or postgresql database backup);
+
+tisbackup.sql
+-------------
+
+:file:`tisbackup.sql` is the :program:`sqlite` database available
+on the backup server, in which the backup information of each
+of the backed up areas is stored. It is used in particular to gather
+the information necessary for Nagios.
+
+TISbackup GUI
+-------------
+
+Also developed in python, TISbackup GUI is a graphical interface
+that allows you to:
+
+* visualize the last backups;
+
+* export a backup to a USB media;
+
+* visualize the backups to be made;
+
+|clap| You may now go on to the next step
+and :ref:`install TISBackup on your Debian<base_debian_server_install>`.
