+        - umount /some/filesystem

 ```
 
+`before_everything` hooks collected from all borgmatic configuration files run
+once before all configuration files (prior to all actions), but only if there
+is a `create` action. An error encountered during a `before_everything` hook
+causes borgmatic to exit without creating backups.
+
+`after_everything` hooks run once after all configuration files and actions,
+but only if there is a `create` action. It runs even if an error occurs during
+a backup or a backup hook, but not if an error occurs during a

+title: How to backup your databases
+---
+## Database dump hooks
+
+If you want to backup a database, it's best practice with most database
+systems to backup an exported database dump, rather than backing up your
+database's internal file storage. That's because the internal storage can
+change while you're reading from it. In contrast, a database dump creates a
+consistent snapshot that is more suited for backups.
+
+Fortunately, borgmatic includes built-in support for creating database dumps
+prior to running backups. For example, here is everything you need to dump and
+backup a couple of local PostgreSQL databases and a MySQL/MariaDB database:
+
+```yaml
+hooks:
+    postgresql_databases:
+        - name: users
+        - name: orders
+    mysql_databases:
+        - name: posts
+```
+
+Prior to each backup, borgmatic dumps each configured database to a file
+(located in `~/.borgmatic/`) and includes it in the backup. After the backup
+completes, borgmatic removes the database dump files to recover disk space.
+
+Here's a more involved example that connects to remote databases:
+
+```yaml
+hooks:
+    postgresql_databases:
+        - name: users
+          hostname: database1.example.org
+          port: 5433
+          username: postgres
+          password: trustsome1
+          format: tar
+          options: "--role=someone"
+    mysql_databases:
+        - name: posts
+          hostname: database2.example.org
+          port: 3307
+          username: root
+          password: trustsome1
+          options: "--skip-comments"
+```
+
+If you want to dump all databases on a host, use `all` for the database name:
+
+```yaml
+hooks:
+    postgresql_databases:
+        - name: all
+    mysql_databases:
+        - name: all
+```
+
+Note that you may need to use a `username` of the `postgres` superuser for
+this to work with PostgreSQL.
+
+
+### Configuration backups
+
+An important note about this database configuration: You'll need the
+configuration to be present in order for borgmatic to restore a database. So
+to prepare for this situation, it's a good idea to include borgmatic's own
+configuration files as part of your regular backups. That way, you can always
+bring back any missing configuration files in order to restore a database.
+
+
+## Supported databases
+
+As of now, borgmatic supports PostgreSQL and MySQL/MariaDB databases
+directly. But see below about general-purpose preparation and cleanup hooks as
+a work-around with other database systems. Also, please [file a
+ticket](https://torsion.org/borgmatic/#issues) for additional database systems
+that you'd like supported.
+
+
+## Database restoration
+
+To restore a database dump from an archive, use the `borgmatic restore`
+action. But the first step is to figure out which archive to restore from. A
+good way to do that is to use the `list` action:
+
+```bash
+borgmatic list
+```
+
+(No borgmatic `list` action? Try the old-style `--list`, or upgrade
+borgmatic!)
+
+That should yield output looking something like:
+
+```text
+host-2019-01-01T04:05:06.070809      Tue, 2019-01-01 04:05:06 [...]
+host-2019-01-02T04:06:07.080910      Wed, 2019-01-02 04:06:07 [...]
+```
+
+Assuming that you want to restore all database dumps from the archive with the
+most up-to-date files and therefore the latest timestamp, run a command like:
+
+```bash
+borgmatic restore --archive host-2019-01-02T04:06:07.080910
+```
+
+(No borgmatic `restore` action? Upgrade borgmatic!)
+
+The `--archive` value is the name of the archive to restore from. This
+restores all databases dumps that borgmatic originally backed up to that
+archive.
+
+This is a destructive action! `borgmatic restore` replaces live databases by
+restoring dumps from the selected archive. So be very careful when and where
+you run it.
+
+
+### Repository selection
+
+If you have a single repository in your borgmatic configuration file(s), no
+problem: the `restore` action figures out which repository to use.
+
+But if you have multiple repositories configured, then you'll need to specify
+the repository path containing the archive to restore. Here's an example:
+
+```bash
+borgmatic restore --repository repo.borg --archive host-2019-...
+```
+
+### Restore particular databases
+
+If you've backed up multiple databases into an archive, and you'd only like to
+restore one of them, use the `--database` flag to select one or more
+databases. For instance:
+
+```bash
+borgmatic restore --archive host-2019-... --database users
+```
+
+### Limitations
+
+There are a few important limitations with borgmatic's current database
+restoration feature that you should know about:
+
+1. You must restore as the same Unix user that created the archive containing
+the database dump. That's because the user's home directory path is encoded
+into the path of the database dump within the archive.
+2. As mentioned above, borgmatic can only restore a database that's defined in
+borgmatic's own configuration file. So include your configuration file in
+backups to avoid getting caught without a way to restore a database.
+3. borgmatic does not currently support backing up or restoring multiple
+databases that share the exact same name on different hosts.
+
+
+### Manual restoration
+
+If you prefer to restore a database without the help of borgmatic, first
+[extract](https://torsion.org/borgmatic/docs/how-to/extract-a-backup/) an
+archive containing a database dump, and then manually restore the dump file
+found within the extracted `~/.borgmatic/` path (e.g. with `pg_restore` or
+`mysql` commands).
+
+
+## Preparation and cleanup hooks
+
+If this database integration is too limited for needs, borgmatic also supports
+general-purpose [preparation and cleanup
+hooks](https://torsion.org/borgmatic/docs/how-to/add-preparation-and-cleanup-steps-to-backups/).
+These hooks allows you to trigger arbitrary commands or scripts before and
+after backups. So if necessary, you can use these hooks to create database
+dumps with any database system.

+title: How to extract a backup
+---
+## Extract
+
+When the worst happens—or you want to test your backups—the first step is
+to figure out which archive to extract. A good way to do that is to use the
+`list` action:
+
+```bash
+borgmatic list
+```
+
+(No borgmatic `list` action? Try the old-style `--list`, or upgrade
+borgmatic!)
+
+That should yield output looking something like:
+
+```text
+host-2019-01-01T04:05:06.070809      Tue, 2019-01-01 04:05:06 [...]
+host-2019-01-02T04:06:07.080910      Wed, 2019-01-02 04:06:07 [...]
+```
+
+Assuming that you want to extract the archive with the most up-to-date files
+and therefore the latest timestamp, run a command like:
+
+```bash
+borgmatic extract --archive host-2019-01-02T04:06:07.080910
+```
+
+(No borgmatic `extract` action? Try the old-style `--extract`, or upgrade
+borgmatic!)
+
+The `--archive` value is the name of the archive to extract. This extracts the
+entire contents of the archive to the current directory, so make sure you're
+in the right place before running the command.
+
+
+## Repository selection
+
+If you have a single repository in your borgmatic configuration file(s), no
+problem: the `extract` action figures out which repository to use.
+
+But if you have multiple repositories configured, then you'll need to specify
+the repository path containing the archive to extract. Here's an example:
+
+```bash
+borgmatic extract --repository repo.borg --archive host-2019-...
+```
+
+## Extract particular files
+
+Sometimes, you want to extract a single deleted file, rather than extracting
+everything from an archive. To do that, tack on one or more `--path` values.
+For instance:
+
+```bash
+borgmatic extract --archive host-2019-... --path path/1 path/2
+```
+
+Note that the specified restore paths should not have a leading slash. Like a
+whole-archive extract, this also extracts into the current directory. So for
+example, if you happen to be in the directory `/var` and you run the `extract`
+command above, borgmatic will extract `/var/path/1` and `/var/path/2`.
+
+## Extract to a particular destination
+
+By default, borgmatic extracts files into the current directory. To instead
+extract files to a particular destination directory, use the `--destination`
+flag:
+
+```bash
+borgmatic extract --archive host-2019-... --destination /tmp
+```
+
+When using the `--destination` flag, be careful not to overwrite your system's
+files with extracted files unless that is your intent.
+
+
+## Database restoration
+
+The `borgmatic extract` command only extracts files. To restore a database,
+please see the [documentation on database backups and
+restores](https://torsion.org/borgmatic/docs/how-to/backup-your-databases/).
+borgmatic does not perform database restoration as part of `borgmatic extract`
+so that you can extract files from your archive without impacting your live
+databases.

+title: How to monitor your backups
+---
+
+## Monitoring and alerting
+
+Having backups is great, but they won't do you a lot of good unless you have
+confidence that they're running on a regular basis. That's where monitoring
+and alerting comes in.
+
+There are several different ways you can monitor your backups and find out
+whether they're succeeding. Which of these you choose to do is up to you and
+your particular infrastructure:
+
+1. **Job runner alerts**: The easiest place to start is with failure alerts
+from the [scheduled job
+runner](https://torsion.org/borgmatic/docs/how-to/set-up-backups/#autopilot) (cron,
+systemd, etc.) that's running borgmatic. But note that if the job doesn't even
+get scheduled (e.g. due to the job runner not running), you probably won't get
+an alert at all! Still, this is a decent first line of defense, especially
+when combined with some of the other approaches below.
+2. **borgmatic error hooks**: The `on_error` hook allows you to run an arbitrary
+command or script when borgmatic itself encounters an error running your
+backups. So for instance, you can run a script to send yourself a text message
+alert. But note that if borgmatic doesn't actually run, this alert won't fire.
+See [error
+hooks](https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#error-hooks)
+below for how to configure this.
+4. **borgmatic monitoring hooks**: This feature integrates with monitoring
+   services like [Healthchecks](https://healthchecks.io/),
+[Cronitor](https://cronitor.io), and [Cronhub](https://cronhub.io), and pings
+these services whenever borgmatic runs. That way, you'll receive an alert when
+something goes wrong or the service doesn't hear from borgmatic for a
+configured interval. See
+[Healthchecks
+hook](https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#healthchecks-hook), [Cronitor
+hook](https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#cronitor-hook), and [Cronhub
+hook](https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#cronhub-hook)
+below for how to configure this.
+3. **Third-party monitoring software**: You can use traditional monitoring
+software to consume borgmatic JSON output and track when the last
+successful backup occurred. See [scripting
+borgmatic](https://torsion.org/borgmatic/docs/how-to/monitor-your-backups/#scripting-borgmatic)
+below for how to configure this.
+5. **Borg hosting providers**: Most [Borg hosting
+providers](https://torsion.org/borgmatic/#hosting-providers) include
+monitoring and alerting as part of their offering. This gives you a dashboard
+to check on all of your backups, and can alert you if the service doesn't hear
+from borgmatic for a configured interval.
+6. **borgmatic consistency checks**: While not strictly part of monitoring, if you
+really want confidence that your backups are not only running but are
+restorable as well, you can configure particular [consistency
+checks](https://torsion.org/borgmatic/docs/how-to/deal-with-very-large-backups/#consistency-check-configuration)
+or even script full [extract
+tests](https://torsion.org/borgmatic/docs/how-to/extract-a-backup/).
+
+
+## Error hooks
+
+When an error occurs during a backup, borgmatic can run configurable shell
+commands to fire off custom error notifications or take other actions, so you
+can get alerted as soon as something goes wrong. Here's a not-so-useful
+example:
+
+```yaml
+hooks:
+    on_error:
+        - echo "Error while creating a backup or running a backup hook."
+```
+
+The `on_error` hook supports interpolating particular runtime variables into
+the hook command. Here's an example that assumes you provide a separate shell
+script to handle the alerting:
+
+```yaml
+hooks:
+    on_error:
+        - send-text-message.sh "{configuration_filename}" "{repository}"
+```
+
+In this example, when the error occurs, borgmatic interpolates a few runtime
+values into the hook command: the borgmatic configuration filename, and the
+path of the repository. Here's the full set of supported variables you can use
+here:
+
+ * `configuration_filename`: borgmatic configuration filename in which the
+   error occurred
+ * `repository`: path of the repository in which the error occurred (may be
+   blank if the error occurs in a hook)
+ * `error`: the error message itself
+ * `output`: output of the command that failed (may be blank if an error
+   occurred without running a command)
+
+Note that borgmatic does not run `on_error` hooks if an error occurs within a
+`before_everything` or `after_everything` hook. For more about hooks, see the
+[borgmatic hooks
+documentation](https://torsion.org/borgmatic/docs/how-to/add-preparation-and-cleanup-steps-to-backups/),
+especially the security information.
+
+
+## Healthchecks hook
+
+[Healthchecks](https://healthchecks.io/) is a service that provides "instant
+alerts when your cron jobs fail silently", and borgmatic has built-in
+integration with it. Once you create a Healthchecks account and project on
+their site, all you need to do is configure borgmatic with the unique "Ping
+URL" for your project. Here's an example:
+
+
+```yaml
+hooks:
+    healthchecks: https://hc-ping.com/addffa72-da17-40ae-be9c-ff591afb942a
+```
+
+With this hook in place, borgmatic pings your Healthchecks project when a
+backup begins, ends, or errors. Specifically, before the <a
+href="https://torsion.org/borgmatic/docs/how-to/add-preparation-and-cleanup-steps-to-backups/">`before_backup`
+hooks</a> run, borgmatic lets Healthchecks know that a backup has started.
+Then, if the backup completes successfully, borgmatic notifies Healthchecks of
+the success after the `after_backup` hooks run. And if an error occurs during
+the backup, borgmatic notifies Healthchecks after the `on_error` hooks run.
+
+You can configure Healthchecks to notify you by a [variety of
+mechanisms](https://healthchecks.io/#welcome-integrations) when backups fail
+or it doesn't hear from borgmatic for a certain period of time.
+
+
+## Cronitor hook
+
+[Cronitor](https://cronitor.io/) provides "Cron monitoring and uptime healthchecks
+for websites, services and APIs", and borgmatic has built-in
+integration with it. Once you create a Cronitor account and cron job monitor on
+their site, all you need to do is configure borgmatic with the unique "Ping
+API URL" for your monitor. Here's an example:
+
+
+```yaml
+hooks:
+    cronitor: https://cronitor.link/d3x0c1
+```
+
+With this hook in place, borgmatic pings your Cronitor monitor when a backup
+begins, ends, or errors. Specifically, before the <a
+href="https://torsion.org/borgmatic/docs/how-to/add-preparation-and-cleanup-steps-to-backups/">`before_backup`
+hooks</a> run, borgmatic lets Cronitor know that a backup has started. Then,
+if the backup completes successfully, borgmatic notifies Cronitor of the
+success after the `after_backup` hooks run. And if an error occurs during the
+backup, borgmatic notifies Cronitor after the `on_error` hooks run.
+
+You can configure Cronitor to notify you by a [variety of
+mechanisms](https://cronitor.io/docs/cron-job-notifications) when backups fail
+or it doesn't hear from borgmatic for a certain period of time.
+
+
+## Cronhub hook
+
+[Cronhub](https://cronhub.io/) provides "instant alerts when any of your
+background jobs fail silently or run longer than expected", and borgmatic has
+built-in integration with it. Once you create a Cronhub account and monitor on
+their site, all you need to do is configure borgmatic with the unique "Ping
+URL" for your monitor. Here's an example:
+
+
+```yaml
+hooks:
+    cronhub: https://cronhub.io/start/1f5e3410-254c-11e8-b61d-55875966d031
+```
+
+With this hook in place, borgmatic pings your Cronhub monitor when a backup
+begins, ends, or errors. Specifically, before the <a
+href="https://torsion.org/borgmatic/docs/how-to/add-preparation-and-cleanup-steps-to-backups/">`before_backup`
+hooks</a> run, borgmatic lets Cronhub know that a backup has started. Then,
+if the backup completes successfully, borgmatic notifies Cronhub of the
+success after the `after_backup` hooks run. And if an error occurs during the
+backup, borgmatic notifies Cronhub after the `on_error` hooks run.
+
+Note that even though you configure borgmatic with the "start" variant of the
+ping URL, borgmatic substitutes the correct state into the URL when pinging
+Cronhub ("start", "finish", or "fail").
+
+You can configure Cronhub to notify you by a [variety of
+mechanisms](https://docs.cronhub.io/integrations.html) when backups fail
+or it doesn't hear from borgmatic for a certain period of time.
+
+
+## Scripting borgmatic
+
+To consume the output of borgmatic in other software, you can include an
+optional `--json` flag with `create`, `list`, or `info` to get the output
+formatted as JSON.
+
+Note that when you specify the `--json` flag, Borg's other non-JSON output is
+suppressed so as not to interfere with the captured JSON. Also note that JSON
+output only shows up at the console, and not in syslog.
+
+
+### Successful backups
+
+`borgmatic list` includes support for a `--successful` flag that only lists
+successful (non-checkpoint) backups. This flag works via a basic heuristic: It
+assumes that non-checkpoint archive names end with a digit (e.g. from a
+timestamp), while checkpoint archive names do not. This means that if you're
+using custom archive names that do not end in a digit, the `--successful` flag
+will not work as expected.
+
+Combined with a built-in Borg flag like `--last`, you can list the last
+successful backup for use in your monitoring scripts. Here's an example
+combined with `--json`:
+
+```bash
+borgmatic list --successful --last 1 --json
+```
+
+Note that this particular combination will only work if you've got a single
+backup "series" in your repository. If you're instead backing up, say, from
+multiple different hosts into a single repository, then you'll need to get
+fancier with your archive listing. See `borg list --help` for more flags.

+See below about special cases with old versions of borgmatic. Additionally, if
+you installed borgmatic [without using `pip3 install
+--user`](https://torsion.org/borgmatic/docs/how-to/set-up-backups/#other-ways-to-install),
+then your upgrade process may be different.
+
+
+### Upgrading your configuration
+
+The borgmatic configuration file format is almost always backwards-compatible
+from release to release without any changes, but you may still want to update
+your configuration file when you upgrade to take advantage of new
+configuration options. This is completely optional. If you prefer, you can add
+new configuration options manually.
+
+If you do want to upgrade your configuration file to include new options, use
+the `generate-borgmatic-config` script with its optional `--source` flag that
+takes the path to your original configuration file. If provided with this
+path, `generate-borgmatic-config` merges your original configuration into the
+generated configuration file, so you get all the newest options and comments.
+
+Here's an example:
+
+```bash
+generate-borgmatic-config --source config.yaml --destination config-new.yaml
+```
+
+New options start as commented out, so you can edit the file and decide
+whether you want to use each one.
+
+There are a few caveats to this process, however. First, when generating the
+new configuration file, `generate-borgmatic-config` replaces any comments
+you've written in your original configuration file with the newest generated
+comments. Second, the script adds back any options you had originally deleted,
+although it does so with the options commented out. And finally, any YAML
+includes you've used in the source configuration get flattened out into a
+single generated file.
+
+As a safety measure, `generate-borgmatic-config` refuses to modify
+configuration files in-place. So it's up to you to review the generated file
+and, if desired, replace your original configuration file with it.
