-## Installation
 
-To get up and running, follow the [Borg Quick
-Start](https://borgbackup.readthedocs.org/en/latest/quickstart.html) to create
-a repository on a local or remote host. Note that if you plan to run borgmatic
-on a schedule with cron, and you encrypt your Borg repository with a
-passphrase instead of a key file, you'll either need to set the borgmatic
-`encryption_passphrase` configuration variable or set the `BORG_PASSPHRASE`
-environment variable. See the [repository encryption
-section](https://borgbackup.readthedocs.io/en/latest/quickstart.html#repository-encryption)
-of the Quick Start for more info.
+## How-to guides
 
-Alternatively, the passphrase can be specified programatically by setting
-either the borgmatic `encryption_passcommand` configuration variable or the
-`BORG_PASSCOMMAND` environment variable. See the [Borg Security
-FAQ](http://borgbackup.readthedocs.io/en/stable/faq.html#how-can-i-specify-the-encryption-passphrase-programmatically)

-
-## Configuration
-
-After you install borgmatic, generate a sample configuration file:
-
-```bash
-sudo generate-borgmatic-config
-```
-
-If that command is not found, then it may be installed in a location that's
-not in your system `PATH`. Try looking in `/usr/local/bin/`.
-
-This generates a sample configuration file at /etc/borgmatic/config.yaml (by
-default). You should edit the file to suit your needs, as the values are just
-representative. All fields are optional except where indicated, so feel free
-to remove anything you don't need.
-
-You can also have a look at the [full configuration
-schema](https://projects.torsion.org/witten/borgmatic/src/master/borgmatic/config/schema.yaml)
-for the authoritative set of all configuration options. This is handy if
-borgmatic has added new options since you originally created your
-configuration file.
-
-
-### Multiple configuration files
-
-A more advanced usage is to create multiple separate configuration files and
-place each one in an /etc/borgmatic.d directory. For instance:
-
-```bash
-sudo mkdir /etc/borgmatic.d
-sudo generate-borgmatic-config --destination /etc/borgmatic.d/app1.yaml
-sudo generate-borgmatic-config --destination /etc/borgmatic.d/app2.yaml
-```
-
-With this approach, you can have entirely different backup policies for
-different applications on your system. For instance, you may want one backup
-configuration for your database data directory, and a different configuration
-for your user home directories.
-
-When you set up multiple configuration files like this, borgmatic will run
-each one in turn from a single borgmatic invocation. This includes, by
-default, the traditional /etc/borgmatic/config.yaml as well.
-
-And if you need even more customizability, you can specify alternate
-configuration paths on the command-line with borgmatic's `--config` option.
-See `borgmatic --help` for more information.
-
-
-### Hooks
-
-If you find yourself performing prepraration tasks before your backup runs, or
-cleanup work afterwards, borgmatic hooks may be of interest. They're simply
-shell commands that borgmatic executes for you at various points, and they're
-configured in the `hooks` section of your configuration file.
-
-For instance, you can specify `before_backup` hooks to dump a database to file
-before backing it up, and specify `after_backup` hooks to delete the temporary
-file afterwards.
-
-borgmatic hooks run once per configuration file. `before_backup` hooks run
-prior to backups of all repositories. `after_backup` hooks run afterwards, but
-not if an error occurs in a previous hook or in the backups themselves. And
-borgmatic runs `on_error` hooks if an error occurs.
-
-An important security note about hooks: borgmatic executes all hook commands
-with the user permissions of borgmatic itself. So to prevent potential shell
-injection or privilege escalation, do not forget to set secure permissions
-(chmod 0700) on borgmatic configuration files and scripts invoked by hooks.
-
-See the sample generated configuration file mentioned above for specifics
-about hook configuration syntax.
-
-
-## Upgrading
-
-In general, all you should need to do to upgrade borgmatic is run the
-following:
-
-```bash
-sudo pip3 install --upgrade borgmatic
-```
-
-However, see below about special cases.
-
-
-### Upgrading from borgmatic 1.0.x
-
-borgmatic changed its configuration file format in version 1.1.0 from
-INI-style to YAML. This better supports validation, and has a more natural way
-to express lists of values. To upgrade your existing configuration, first
-upgrade to the new version of borgmatic.
-
-As of version 1.1.0, borgmatic no longer supports Python 2. If you were
-already running borgmatic with Python 3, then you can simply upgrade borgmatic
-in-place:
-
-```bash
-sudo pip3 install --upgrade borgmatic
-```
-
-But if you were running borgmatic with Python 2, uninstall and reinstall instead:
-
-```bash
-sudo pip uninstall borgmatic
-sudo pip3 install borgmatic
-```
-
-The pip binary names for different versions of Python can differ, so the above
-commands may need some tweaking to work on your machine.
-
-
-Once borgmatic is upgraded, run:
-
-```bash
-sudo upgrade-borgmatic-config
-```
-
-That will generate a new YAML configuration file at /etc/borgmatic/config.yaml
-(by default) using the values from both your existing configuration and
-excludes files. The new version of borgmatic will consume the YAML
-configuration file instead of the old one.
-
-
-### Upgrading from atticmatic
-
-You can ignore this section if you're not an atticmatic user (the former name
-of borgmatic).
-
-borgmatic only supports Borg now and no longer supports Attic. So if you're
-an Attic user, consider switching to Borg. See the [Borg upgrade
-command](https://borgbackup.readthedocs.io/en/stable/usage.html#borg-upgrade)
-for more information. Then, follow the instructions above about setting up
-your borgmatic configuration files.
-
-If you were already using Borg with atticmatic, then you can easily upgrade
-from atticmatic to borgmatic. Simply run the following commands:
-
-```bash
-sudo pip3 uninstall atticmatic
-sudo pip3 install borgmatic
-```
-
-That's it! borgmatic will continue using your /etc/borgmatic configuration
-files.
-
-
-## Usage
-
-You can run borgmatic and start a backup simply by invoking it without
-arguments:
-
-```bash
-borgmatic
-```
-
-This will also prune any old backups as per the configured retention policy,
-and check backups for consistency problems due to things like file damage.
-
-If you'd like to see the available command-line arguments, view the help:
-
-```bash
-borgmatic --help
-```
-
-Note that borgmatic prunes archives *before* creating an archive, so as to
-free up space for archiving. This means that when a borgmatic run finishes,
-there may still be prune-able archives. Not to worry, as they will get cleaned
-up at the start of the next run.
-
-### Verbosity
-
-By default, the backup will proceed silently except in the case of errors. But
-if you'd like to to get additional information about the progress of the
-backup as it proceeds, use the verbosity option:
-
-```bash
-borgmatic --verbosity 1
-```
-
-Or, for even more progress spew:
-
-```bash
-borgmatic --verbosity 2
-```
-
-### À la carte

-If you want to run borgmatic with only pruning, creating, or checking enabled,
-the following optional flags are available:
-
-```bash
-borgmatic --prune
-borgmatic --create
-borgmatic --check
-```
-
-You can run with only one of these flags provided, or you can mix and match
-any number of them. This supports use cases like running consistency checks
-from a different cron job with a different frequency, or running pruning with
-a different verbosity level.
-
-
-## Autopilot
-
-If you want to run borgmatic automatically, say once a day, the you can
-configure a job runner to invoke it periodically.
-
-### cron
-
-If you're using cron, download the [sample cron
-file](https://projects.torsion.org/witten/borgmatic/src/master/sample/cron/borgmatic).
-Then, from the directory where you downloaded it:
-
-```bash
-sudo mv borgmatic /etc/cron.d/borgmatic
-sudo chmod +x /etc/cron.d/borgmatic
-```
-
-You can modify the cron file if you'd like to run borgmatic more or less frequently.
-
-### systemd
-
-If you're using systemd instead of cron to run jobs, download the [sample
-systemd service
-file](https://projects.torsion.org/witten/borgmatic/src/master/sample/systemd/borgmatic.service)
-and the [sample systemd timer
-file](https://projects.torsion.org/witten/borgmatic/src/master/sample/systemd/borgmatic.timer).
-Then, from the directory where you downloaded them:
-
-```bash
-sudo mv borgmatic.service borgmatic.timer /etc/systemd/system/
-sudo systemctl enable borgmatic.timer
-sudo systemctl start borgmatic.timer
-```
-
-Feel free to modify the timer file based on how frequently you'd like
-borgmatic to run.

-### Code style
-
-Start with [PEP 8](https://www.python.org/dev/peps/pep-0008/). But then, apply
-the following deviations from it:
-
- * For strings, prefer single quotes over double quotes.
- * Limit all lines to a maximum of 100 characters.
- * Use trailing commas within multiline values or argument lists.
- * For multiline constructs, put opening and closing delimeters on lines
-   separate from their contents.
- * Within multiline constructs, use standard four-space indentation. Don't align
-   indentation with an opening delimeter.
-
-
-### Development
-
-To get set up to hack on borgmatic, first clone master via HTTPS or SSH:
-
-```
-git clone https://projects.torsion.org/witten/borgmatic.git
-```
-
-Or:
-
-```bash
-git clone ssh://git@projects.torsion.org:3022/witten/borgmatic.git
-```
-
-Then, install borgmatic
-"[editable](https://pip.pypa.io/en/stable/reference/pip_install/#editable-installs)"
-so that you can easily run borgmatic commands while you're hacking on them to
-make sure your changes work.
-
-```bash
-cd borgmatic/
-pip3 install --editable --user .
-```
-
-Note that this will typically install the borgmatic commands into
-`~/.local/bin`, which may or may not be on your PATH. There are other ways to
-install borgmatic editable as well, for instance into the system Python
-install (so without `--user`, as root), or even into a
-[virtualenv](https://virtualenv.pypa.io/en/stable/). How or where you install
-borgmatic is up to you, but generally an editable install makes development
-and testing easier.
-
-
-### Running tests
-
-Assuming you've cloned the borgmatic source code as described above, and
-you're in the `borgmatic/` working copy, install tox, which is used for
-setting up testing environments:
-
-```bash
-sudo pip3 install tox
-```
-
-Finally, to actually run tests, run:
-
-```bash
-cd borgmatic
-tox
-```
-
-
-## Troubleshooting
-
-### Broken pipe with remote repository
-
-When running borgmatic on a large remote repository, you may receive errors
-like the following, particularly while "borg check" is validating backups for
-consistency:
-
-```text
-    Write failed: Broken pipe
-    borg: Error: Connection closed by remote host
-```
-
-This error can be caused by an ssh timeout, which you can rectify by adding
-the following to the ~/.ssh/config file on the client:
-
-```text
-    Host *
-        ServerAliveInterval 120
-```
-
-This should make the client keep the connection alive while validating
-backups.
-
-
-### libyaml compilation errors
-
-borgmatic depends on a Python YAML library (ruamel.yaml) that will optionally
-use a C YAML library (libyaml) if present. But if it's not installed, then
-when installing or upgrading borgmatic, you may see errors about compiling the
-YAML library. If so, not to worry. borgmatic should install and function
-correctly even without the C YAML library. And borgmatic won't be any faster
-with the C library present, so you don't need to go out of your way to install
-it.

+title: Add preparation and cleanup steps to backups
+---
+## Preparation and cleanup hooks
+
+If you find yourself performing prepraration tasks before your backup runs, or
+cleanup work afterwards, borgmatic hooks may be of interest. Hooks are
+shell commands that borgmatic executes for you at various points, and they're
+configured in the `hooks` section of your configuration file.
+
+For instance, you can specify `before_backup` hooks to dump a database to file
+before backing it up, and specify `after_backup` hooks to delete the temporary
+file afterwards. Here's an example:
+
+```yaml
+hooks:
+    before_backup:
+        - dump-a-database /to/file.sql
+    after_backup:
+        - rm /to/file.sql
+```
+
+borgmatic hooks run once per configuration file. `before_backup` hooks run
+prior to backups of all repositories. `after_backup` hooks run afterwards, but
+not if an error occurs in a previous hook or in the backups themselves.
+
+
+## Error hooks
+
+borgmatic also runs `on_error` hooks if an error occurs, either when creating
+a backup or running another hook. Here's an example configuration:
+
+```yaml
+hooks:
+    on_error:
+        - echo "Error while creating a backup or running a hook."
