## Chapter 36. HTTPBackupAgent and backup client

### Warning

For this service, you should configure the org.exoplatform.services.jcr.impl.config.JDBCConfigurationPersister in order to save the changes of the repository configuration. See the eXo JCR Configuration article at chapter '2 Portal and Standalone configuration' .

GateIn uses context /portal/rest, therefore you need to use http://host:port/portal/rest/ instread of http://host:port/rest/

GateIn uses form authentication, so first you need to login (url to form authentication is http://host:port/portal/login) and then perform requests.

## Introduction

The service org.exoplatform.services.jcr.ext.backup.server.HTTPBackupAgent is REST-based front-end to service org.exoplatform.services.jcr.ext.backup.BackupManager. HTTPBackupAgent is representation BackupManager to creation backup, restore, getting status of current or completed backup/restore, etc.

The backup client is http client for HTTPBackupAgent.

## HTTPBackupAgent

The HTTPBackupAgent is based on REST (see details about the REST Framework).

HTTPBackupAgent is using POST and GET methods for request.

The HTTPBackupAgent allows :

- Start backup

- Stop backup

- Restore from backup

- Delete the workspace

- Get information about backup service (BackupManager)

- Get information about current backup / restores / completed backups

### HTTPBackupAgent Configuration

Add the components org.exoplatform.services.jcr.ext.backup.server.HTTPBackupAgent and org.exoplatform.services.jcr.ext.backup.BackupManager to services configuration :

    <component>

      <type>org.exoplatform.services.jcr.ext.backup.server.HTTPBackupAgent</type>

    </component>

    <component>

      <type>org.exoplatform.services.jcr.ext.repository.RestRepositoryService</type>

    </component>

    <component>

      <key>org.exoplatform.services.jcr.ext.backup.BackupManager</key>

      <type>org.exoplatform.services.jcr.ext.backup.impl.BackupManagerImpl</type>

      <init-params>

        <properties-param>

          <name>backup-properties</name>

          <property name="backup-dir" value="../temp/backup" />

        </properties-param>

      </init-params>

    </component>

In case, if you will restore backup in same workspace (so you will drop previous workspace), you need configure RepositoryServiceConfiguration in order to save the changes of the repository configuration. For example

    <component>

      <key>org.exoplatform.services.jcr.config.RepositoryServiceConfiguration</key>

      <type>org.exoplatform.services.jcr.impl.config.RepositoryServiceConfigurationImpl</type>

      <init-params>

        <value-param>

          <name>conf-path</name>

          <description>JCR repositories configuration file</description>

          <value>jar:/conf/portal/exo-jcr-config.xml</value>

        </value-param>

        <properties-param>

          <name>working-conf</name>

          <description>working-conf</description>

          <property name="source-name" value="jdbcjcr" />

          <property name="dialect" value="hsqldb" />

          <property name="persister-class-name" value="org.exoplatform.services.jcr.impl.config.JDBCConfigurationPersister" />

        </properties-param>

      </init-params>

    </component>

See the eXo JCR Configuration article at chapter '2 Portal and Standalone configuration' for details.

## Backup Client

For GateIn should use context "/portal/rest". GateIn uses form authentication, so first you need to login (url to form authentication is http://host:port/portal/login) and then perform requests.

Backup client is support form authentication. For example call command "info" with form authentication to GateIn :

./jcrbackup.sh http://127.0.0.1:8080/portal/rest form POST "/portal/login?initialURI=/portal/private&username=root&password=gtn" info

Backup client is console application.

The backup client is http client for HTTPBackupAgent.

Command signature:

    Help info:
     <url_basic_authentication>|<url form authentication>  <cmd>
     <url_basic_authentication>  :   http(s)//login:password@host:port/<context>

     <url form authentication>   :   http(s)//host:port/<context> "<form auth parm>"
         <form auth parm>        :   form <method> <form path>
         <method>                :   POST or GET
         <form path>             :   /path/path?<paramName1>=<paramValue1>&<paramName2>=<paramValue2>...
         Example to <url form authentication> : http://127.0.0.1:8080/portal/rest form POST "/portal/login?initialURI=/portal/private&username=root&password=gtn"

     <cmd>  :   start <repo[/ws]> <backup_dir> [<incr>]
