Standard Mode

Updated: July 11, 2024

Before You Start

This page gives all the necessary steps to install the Retention Management addon in standard mode.


Using the Retention Management addon requires storing files in Amazon S3. Other cloud platforms or storage options are not supported.


This addon requires no specific installation steps. It can be installed like any other package with nuxeoctl command line or from the Marketplace.


Setting the Addon in Standard Mode

Setting the addon in standard mode is done through the following nuxeo.conf property:


Since LTS 2021 HF41, this property replaces and supersedes the property nuxeo.retention.compliance.enabled: if both are set, the value of nuxeo.retention.strictmode.enabled will be used.

Amazon S3 Architecture Options

In Standard mode, there are 3 supported configurations using Amazon S3:

  • Storing records in a dedicated S3 bucket with Object Lock (recommended)
  • Storing records in a dedicated S3 bucket without Object Lock
  • Storing records in the same bucket as other documents

Our recommendation is to have a dedicated bucket for records. This option provides greater flexibility in the long run, and facilitates demonstrating compliance.

Depending on your compliance needs, the dedicated bucket can leverage Amazon S3 Object Lock in governance mode, or in compliance mode to provide compliance with the SEC-17A4 regulation.

Activating Object Lock and choosing a mode for it must be done during the creation of the bucket. Please consider your needs and the regulations you will be subject to before installing and configuring the addon.

Storing Records in a Dedicated S3 Bucket

It is possible to configure an additional S3 bucket dedicated to storing records. This can be configured using an XML contribution, or via the nuxeo.conf configuration file.

Configure via XML Contribution

Configure the standard S3 bucket as described in Amazon S3 Online Storage. Once complete, add an XML extension file to configure the bucket that will be used for records:

  • The file has to be added to $NUXEO_HOME/nxserver/config
  • The file name has to be ended with -config.xml
  • The file must contain the following component name:
<component name="records-s3-compliance">
  • The file must contain a blob manager contribution with the following parameters:
<extension target="org.nuxeo.ecm.core.blob.BlobManager" point="configuration">
    <blobprovider name="records">
      <property name="record">true</property>
  • The file must contain a blob dispatcher contribution as shown here:
<extension target="org.nuxeo.ecm.core.blob.DocumentBlobManager" point="configuration">
      <property name="records">records</property>
      <property name="default">default</property>

This configuration is only applicable when using the Retention addon with a dedicated S3 bucket for the records.

If you want to configure your instance with a single bucket and NO support for Object Lock now or in the future, please refer to the single bucket architecture.

Here is the complete XML extension file example:

<?xml version="1.0"?>
<component name="records-s3-compliance">


  <extension target="org.nuxeo.ecm.core.blob.BlobManager" point="configuration">
    <blobprovider name="records">
      <property name="record">true</property>
      <property name="awsid">${nuxeo.s3storage.awsid}</property>
      <property name="awssecret">${nuxeo.s3storage.awssecret}</property>
      <property name="awstoken">${nuxeo.s3storage.awstoken}</property>
      <property name="bucket">Your S3 bucket for records</property>

      <!-- min file age, in second, to be removed from cache if the size max size is reached, default is 3600 -->
      <property name="cacheminage">60</property>
      <property name="cachesize">100MB</property>
      <property name="connection.max">50</property>
      <property name="connection.retry">3</property>
      <property name="connection.timeout">50000</property>
      <property name="socket.timeout">50000</property>

  <extension target="org.nuxeo.ecm.core.blob.DocumentBlobManager" point="configuration">
      <property name="records">records</property>
      <property name="default">default</property>
Configure via nuxeo.conf

Add the s3retention template to the nuxeo.templates property in the nuxeo.conf file:


This will enable the s3-retention-config.xml config, which enables the following properties for nuxeo.conf:

  • nuxeo.retention.s3storage.bucket
  • nuxeo.retention.s3storage.bucket_prefix
  • nuxeo.retention.s3storage.awsid
    (fallback to nuxeo.s3storage.awsid)

    (fallback to nuxeo.s3storage.awstoken)
  • nuxeo.retention.s3storage.region
    (fallback to nuxeo.s3storage.region)
  • nuxeo.retention.core.blobstore.digestAsync

Store Records in a Dedicated S3 Bucket With S3 Object Lock

Amazon S3 Object Lock prevents the deletion of content under retention until the retention period has expired. Nuxeo Retention, when configured to use Amazon S3 Object Lock, automatically provides the retention period (or legal hold) to Amazon S3.

To configure the Retention addon with a dedicated S3 bucket with Object Lock, first follow the steps described in the dedicated bucket architecture. Next configure the record bucket as follows:

  • Direct writes to the Amazon S3 storage system must be disabled; this is to ensure that all documents pass through Nuxeo Platform for compliant processing.

  • The Amazon S3 Object Lock feature must be enabled on the record bucket. If you intend to be compliant with SEC-17A4, you must use Object Lock in Compliance mode.

  • Amazon S3 Versioning must be enabled; this is automatically done when enabling Object Lock.

  • The default retention value for the record bucket must not be set (or, at least, set to zero).

  • No min/max range should be established for the record bucket.

  • Amazon S3 Lifecycle Policies must not be configured for use within the Nuxeo Platform storage subsystem.

Alternative Option

Records can also be stored in the same bucket as the rest of the content. This provides a simpler architecture, but restricts the possibility to adapt to more complex scenarios in the long run.

Storing Records in the Same Bucket as Other Documents

This configuration consists on using the same S3 bucket for records and other documents.

In this case, you can use the Amazon S3 addon with the default configuration with the Retention addon.

This configuration does NOT allow using the Amazon S3 Object Lock feature (no WORM storage option).

This configuration is only compliant with the binary manager
