A Guide to Recover Deleted Slack Data

29 Mar 2022

7 min read

Slack is one of the most popular workspace communication and collaboration tools available globally. Currently a part of Salesforce, the application has seen steady growth since its inception and now has over 12 million daily active users (DAUs).

What happens when Slack data gets deleted?

Slack does not have a built-in recycle bin. This means, users cannot retrieve deleted messages, channels, or files directly from Trash. Below is an illustration of how data deletion works in Slack.

While organizations cannot prevent accidental deletion, there are different methods available to help recover deleted Slack data.

Below are three ways to retrieve deleted Slack data:

using Slack eDiscovery
recovering from exported Slack data
using a third-party Slack backup solution

How to recover deleted Slack data using the native eDiscovery tool

eDiscovery is the process of identifying, reviewing, and preserving electronically stored information to be presented as evidence in a legal proceeding. Slack’s eDiscovery API export mechanism allows organizations with Enterprise Grid subscription to use pre-approved third-party applications to export any organizational content- which includes data that was edited or deleted. Users can export deleted messages from public channels, private channels, and direct messages and files (accessible through direct download links).

How to export data using Slack’s eDiscovery API

Organizations with Slack Enterprise Grid subscriptions are connected to a third-party eDiscovery partner using Slack’s eDiscovery API, to export and store Slack data from multiple workspaces. These eDiscovery apps export messages and files from Slack and store the information in a third-party data warehouse.

These apps typically have read-only access to Slack message and file data and they cannot remove or quarantine the data within Slack. Exported messages and files can be searched, archived, or retrieved from these data warehouses.

Limitations of exporting data using Slack eDiscovery

eDiscovery is only available for Enterprise Grid subscription users.
The primary org owner or an org owner must request the Slack Support team to enable the Discovery API.

How to recover Slack data using the Slack import and export tool

Slack’s native import and export tool allows organizations to export their Slack data manually or by scheduled exports of your data (daily, weekly, or monthly).

The data exported will be available in JSON format. Admins can then download their exported Slack workspace to their local computers or third-party storage like S3 or Dropbox.

How to import Slack data

Organizations can recover lost or deleted data by importing it from exports created using the Slack import and export tool.

Follow the below steps to learn how to import downloaded Slack data using Slack import and export tool:

Step 1: Upload the zipped export file to a secure cloud service, such as Google Drive, Dropbox, or Box, and generate a public direct download link (make sure to keep this link to hand). (This step can be skipped, and the file can be uploaded directly during Step 5).
Step 2: Click the workspace name on the top left.
Step 3: Select Settings & administration, then choose Workspace settings from the menu.

Step 4: Click on Import/Export data. Next to Slack, select Import.

Step 5: Paste the link to the export file into the Direct download link field or click on Upload it directly and choose the zipped export file from the local machine.
Step 6: Click on Upload file.
Step 7: An email will be sent when the upload is completed.

Limitations of recovering deleted Slack data using the Import Export tool

Only workspace owners can import data into Slack.
There is a limit to the amount of data that the tool can process at once. The export file might have to be split into multiple date ranges and processed as different imports
Exporting and importing Slack data using the native tool is a time-consuming process since export must be set up manually for all plans except for Business+ subscription. If there is a large amount of data to be imported- it needs to be split into different date ranges. These might lead to further data loss.
Owners cannot select specific messages or files to be imported back to the application.
If internet access is lost, import progress is interrupted, and you will have to begin all over again.
