+Disaster recovery
+-----------------

+
+In case of major disasters, important data, or even whole servers might be destroyed
+or at least damaged up to the point where everything - sometimes including the backup
+server - has to be restored from a backup. For such cases, the following step-by-step
+guide will help you to setup the Proxmox Backup Server and restore everything from
+tape backups.
+
+The following guide will explain the necessary steps using both the web GUI and the
+command line tools. For an overview of the command line tools,
+see `Command-line Tools`_.
+
+Restoring hardware
+~~~~~~~~~~~~~~~~~~
+
+.. _System Requirements: system-requirements.html
+
+.. _Installation Medium: installation-media.html
+
+.. _Server Installation: installation.html
+
+#. In case you need to buy new a new server, please consult the `System Requirements`_
+ for the Proxmox Backup Server.
+
+#. Make sure that the new server has power and starts without issues.
+
+#. Download the Proxmox Backup Server and create an `Installation Medium`_.
+
+#. Follow the :ref:`install_pbs` steps and install the Proxmox Backup
+ Server on the new hardware.
+
+
+Setting up a datastore
+~~~~~~~~~~~~~~~~~~~~~~
+
+.. _proxmox-backup-manager: proxmox-backup-manager/man1.html
+
+A datastore on the Proxmox Backup Server is necessary in order to perform a restore
+from a tape to the local datastore. You will need to do the following:
+
+#. Go to **Administration -> Storage / Disks** and make sure that the disk that will be used
+ as a datastore shows up.
+
+#. Under the **Directory** or **ZFS** tabs, you can either choose to create a directory
+ or create a ZFS ``zpool``, respectively. Here you can also directly add the newly created
+ directory or ZFS ``zpool`` as a datastore.
+
+Alternatively, the `proxmox-backup-manager`_ can be used to perform the same tasks.
+For more information, check the :ref:`datastore_intro` documentation.
+
+
+Setting up the tape drive
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+#. Make sure that you have a tape drive that is able to read the tape that
+ you want to restore from. Keep in mind that the Proxmox Backup Server supports LTO-5 or
+ later, although some LTO-4 might also work (see :ref:`tape-supported-hardware`).
+
+ As a short overview, in order to get everything working, you will need to set up the following:
+ * a tape drive
+ * optionally, a tape changer
+ * a cable to connect the tape drive(s) to the backup server
+ * physical storage on your backup server to restore data from the tape
+
+#. Connect the tape changer(s) and the tape drive(s) to the backup server. These should be
+ detected automatically by Linux. For more advanced information, please read the chapters
+ on :ref:`tape_changer_config` and :ref:`tape_drive_config`.
+
+#. If you have a tape changer, go to the web interface of the Proxmox Backup Server,
+ go to **Tape Backup -> Changers** and add it. For examples using the command line, read
+ the chapter on :ref:`tape_changer_config`. If the changer has been detected correctly by Linux,
+ the changer should show up in the list.
+
+#. In the web interface, go to **Tape Backup -> Drives** and add the tape drive that will be
+ used to read the tapes. For examples using the command line, read
+ the chapter on :ref:`tape_drive_config`. If the tape drive has been detected correctly by Linux,
+ the drive should show up in the list. If the drive also has a tape changer, make sure to
+ select the changer as well and assign it the correct drive number.
+
+
+Restoring data from the tape
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. _proxmox-tape: proxmox-tape/man1.html
+
+.. _proxmox-backup-client: proxmox-backup-client/man1.html
+
+.. _Restore: https://pve.proxmox.com/pve-docs/chapter-vzdump.html#vzdump_restore
+
+The following guide will explain the steps necessary to restore data from a tape, which can be
+done over either the web GUI or the command line. For details on the command line, read the
+documentation on the `proxmox-tape`_ tool.
+
+To restore data from tapes, do the following:
+
+#. Insert the first tape (as displayed on the label) into the tape drive or, if a tape changer
+ is available, use the tape changer to insert the tape into the right drive.
+ The web GUI can also be used to load or transfer tapes between tape drives
+ by selecting the changer.
+
+#. If the backup has been encrypted, the encryption keys need to be restored as well. In the
+ **Encryption Keys** tab, press **Restore Key**. For more details or examples that use the command line,
+ read the :ref:`tape_key_management` chapter.
+
+#. In order to restore data, you need to find out which media set contains the data that
+ should be restored. A media catalog stores this information, so if specific files need to be
+ restored, the media catalog needs to be restored first in order to find which files exist
+ on the tape. While it is possible to restore data from a tape that does not contain a catalog,
+ it is only possible to restore the whole media set. To restore a catalog, do the following:
+
+ * If a tape changer is used, click on the **Tape Changer**, go to **Inventory** and make sure
+ **Restore Catalog** is selected. This will restore the catalogs of all tapes in the changer.
+ Alternatively, tapes can also be loaded into drives, where pressing **Catalog** will restore
+ the catalog only for the currently loaded tape.
+
+ * If a standalone tape drive is used, click on the drive and click on **Catalog**.
+
+#. Go back to **Tape Backup**. In the **Content** tab, press **Restore** and select the desired media set.
+ Choose the snapshot you want to restore, press **Next**, select the drive and target datastore
+ and press **Restore**.
+
+#. By going to the datastore where the data has been restored, under the **Content** tab you should
+ be able to see the restored snapshots. In order to access the backups from another machine,
+ you will need to configure the access to the backup server. Go to **Configuration -> Access Control**
+ and either create a new user, or a new API token (API tokens allow easy revocation if the token
+ is compromised). Under **Permissions**, add the desired permissions, e.g. **DatastoreBackup**.
+
+#. You can now perform virtual machine, container or file restores. You now have
+ the following options:
+
+ * If you want to restore files on Linux distributions that are not based on Proxmox products
+ or you prefer using a command line tool, you can use the `proxmox-backup-client`_,
+ as explained in the :ref:`client_restoring_data` chapter. Use the newly created API token to be
+ able to access the data. You can then restore individual files or mount an archive to your system.
+
+ * If you want to restore virual machines or containers on a Proxmox VE server, add the datastore
+ of the backup server as storage and go to **Backups**. Here you can restore VMs and containers,
+ including their configuration. For more information on restoring backups in the Proxmox VE, visit
+ the `Restore`_ chapter of the Proxmox VE documentation.
