Google Chat retention at a glance

• Google Chat lacks native retention policies and automated recovery options, making data protection challenging. • Google Vault offers limited retention and archiving capabilities, applicable only to specific licenses.

What is the solution? SysCloud provides automated, continuous backups and comprehensive retention solutions, ensuring all Google Chat data is protected and easily recoverable.

Google Chat (previously known as Google Hangout)is a collaborative application within Google Workspace. From direct messages to group conversations, Google Chat and Spaces (previously known as Google Chat Roomsor Rooms), help teams to collaborate easily and effectively from anywhere. Users can upload files, share Google Drive files, add video meetings, and schedule calendar events through Google Chat.

Default Chat retention in Google Workspace

Google Chat doesn’t have a trash folder. As a result, when you delete a message or conversation in Chat, it is permanently deleted.

The advanced licenses of Google Workspace offer an extra layer of native data retention using Google Vault. Administrators can use Google Vault to retain messages for longer periods even after it was deleted by a user.

Google Vault can:

Retain organizational data indefinitely or for a certain time period
Automatically delete organizational data after a certain time
Hold, search, and export organizational data for eDiscovery

To know more about what Google Vault is, Vault retention rules, holds, and license requirements, read our in-depth article on Google Vault Fundamentals.

Types of retention for Chat messages using Vault

Google Workspace administrators can set two types of retention rules for Google Drive files.

Default retention rules
Custom retention rules

The default retention rule applies to all DMs, group messages, and Chat spaces in your organization. A custom retention rule can apply to different sets of messages:

Organizational unit-based retention rule	"All Chat spaces" retention rule
DMs in classic Hangouts and Chat	Threaded spaces (spaces with messages in conversations)
Group conversations in classic Hangouts	Unthreaded spaces (spaces with messages in a single thread, like DMs)
Group chats in Chat created before early December 2020	Group chats in Chat created after early December 2020

If more than one custom retention rule is applied to a message, the custom rule that expires last becomes valid.

What happens when a Chat message covered by a retention rule gets deleted?

Google Chat messages or conversations cannot be permanently deleted once a retention rule is applied to it. The retention period starts the day the message is sent. It doesn't change when a user edits or deletes a message. If a user deletes a message that falls within the scope of the retention rule, it simply gets removed from the user’s account but will be still available in Google Vault for the super administrator.

Chat messages are kept for additional 30 days after a user, or a retention rule removes them from a conversation or a space. The purge process begins on Day 30 and may take several additional days to complete depending on the number of messages being purged.

Below is a diagram that explains what happens to a Google Chat message once it is deleted.

Some additional information about Chat retention:

To retain, hold, search, and export direct messages (DMs), group messages, and unthreaded spaces chat history must be turned on
Files stored in Drive shared as a link through Chat are not retained in Chat retention.
Files that are directly attached to a Chat message are included in Chat retention.
Messages to and from external users are subjected to your organization's retention rules and holds.
If users in your organization participate in group messages and spaces owned by another organization, those messages aren’t available to your organization through Vault for retention, holds, search, or export.
Retention periods depend on who the participant is.
Direct message (DMs): When participants are in the same organization but covered by different retention rules, one participant might be able to access a DM while the other can’t depending upon their respective retention period.
DMs with external users: When participants belong to different organizations, DMs are retained according to each organization’s retention rules.
Chat spaces: When you set a default retention rule or create a custom retention rule for Chat, Vault can retain messages only in spaces that have history turned on.
External users in Chat spaces: When participants belong to different organizations, the conversation is retained according to the rules of the organization of the space's creator. If users in your organization participate in spaces owned by another organization, those messages aren’t available to Vault for retention, holds, search, or export.

How to safeguard Chat messages using retention rules in Google Vault?

Create a custom retention rule for Chat message

Sign in to Google Vault
Click Retention > Custom Rules > Create
Select Chat and then click Continue.
Choose an entity:
To retain DMs and group conversations that were sent or received by accounts in an organizational unit, select Organizational unit. Click the organizational unit field and, in the dialog that opens, click the organizational unit or to retain messages in all spaces in your organization, select All Chat spaces. The rule doesn't apply to direct messages or some group messages.
Choose how long to keep messages:
To permanently retain messages covered by this rule, choose Indefinitely or to discard messages after a set time, choose Retention period and enter the number of days, from 1 to 36,500.
Click Create.
Confirm the settings.

Note: Once you set a retention period, Vault will immediately delete files that exceed the retention period when you create the retention rule. If not configured properly this may delete data that was not meant to be purged.

Create a default retention rule for Chat message

Sign in to Google Vault.
Click Retention. The list of default rules opens.
Click Chat.
Define how long you want to keep messages.
Click Save.
Confirm the settings and click Accept to save the rule.

How to use eDiscovery to safeguard Chat messages?

eDiscovery(offered by Google Vault) allows the Google Workspace administratorto create holds topreserve Chat messages indefinitely to meet legal orother purposes.Administrator canapply a hold to individual accounts or all accounts in an organizational unit.

Note: Holds override retention rules

Unlike Chat retention rules, holds can be placed only on individual accounts or organizational units. Holds can't be set on Chat spaces exclusively. Vault holds messages if a user on hold was a member of the group chat, even if they didn’t send any messages. If all users on hold leave a group chat, only messages sent before the last user on hold left are included in the hold. Holds don't apply to messages sent in Chat spaces owned by another organization.

What happens when a Chat message on hold is deleted?

When a Chat message on hold is deleted, the user can't access the message anymore. However, as a Vault user, you can search, preview, and export the message using Vault.

Are Google Vault retention and eDiscovery hold ideal data backup solutions?

No, Google Vault retention and eDiscovery are not ideal data backup solutions. Google Vault is a data retention solution aimed to preserve and critical business data for litigation purposes. It shouldn't be confused with a backup solution. One major difference between a retention solution and a backup solution is that a retention solution is only concerned with retaining data while a backup solution offers an easy method to restore this data back into your account. To learn more about Retention vs Backup, read our in-depth article. Unlike Vault, third-party backup solutions like SysCloud offer features like automated backups, single-click restores, cross-user restore that decreases recovery times and minimizes the negative impact on productivity.

Why is Google Vault not the ideal Google Chat backup solution?

User deletions: Once a user is deleted from your Google Workspace account, all the Chat messages associated with the user account also gets deleted even if it was on hold or covered by a retention policy.
Absence of restore options: Chat messages that are preserved though Google Vault (hold or retention policies) can only be exported and not directly restored back into your account.
Google outages: Unexpected Google outages can result in data being inaccessible for hours. With Vault being a Google service, will not be of much use during outages.
Ransomware attacks: If your account is locked by a ransomware, the data retained and held in Google Vault will also be affected.

Third-party cloud backup solutions like SysCloud are a one stop solution to your data backup and restore problems.
