Quick start

import CodeBlock from '@theme/CodeBlock'; import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem'; import TOCInline from '@theme/TOCInline'; import {Version} from '@site/src/corsoEnv'; import DownloadBinaries from './setup/_download_binary.md';

This quick start guide runs through the steps you can follow to create your first Microsoft 365 backup and restore:

Download Corso

Download a Corso binary for your platform. If you would like to use a Docker container, the first docker run will pull the image.

Connect to Microsoft 365

Obtaining credentials from Microsoft 365 to allow Corso to run is a one-time operation. Follow the instructions here to obtain the necessary credentials and then make them available to Corso.

$Env:AZURE_CLIENT_ID = "<Application (client) ID for configured app>"
$Env:AZURE_TENANT_ID = "<Directory (tenant) ID for configured app>"
$Env:AZURE_CLIENT_SECRET = "<Client secret value>"

export AZURE_CLIENT_ID=<Application (client) ID for configured app>
export AZURE_TENANT_ID=<Directory (tenant) ID for configured app>
export AZURE_CLIENT_SECRET=<Client secret value>

export AZURE_CLIENT_ID=<Application (client) ID for configured app>
export AZURE_TENANT_ID=<Directory (tenant) ID for configured app>
export AZURE_CLIENT_SECRET=<Client secret value>

Create a Corso repository

To create a secure backup location for Corso, you will first need to download Corso. Use the container or native executable to initialize the Corso repository using an encryption passphrase and a pre-created S3 bucket (Corso doesn't create the bucket if it doesn't exist). The steps below use corso-test as the bucket name but, if you are using AWS, you will need a different unique name for the bucket.

The following commands assume that in addition to the configuration values from the previous step, AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY (and AWS_SESSION_TOKEN if you are using temporary credentials) are available to the Corso binary or container.

# Initialize the Corso Repository
$Env:CORSO_PASSPHRASE = "CHANGE-ME-THIS-IS-INSECURE"
.\corso repo init s3 --bucket corso-test

# Initialize the Corso Repository
export CORSO_PASSPHRASE="CHANGE-ME-THIS-IS-INSECURE"
./corso repo init s3 --bucket corso-test

{ `# Create an environment variables file mkdir -p $HOME/.corso cat < $HOME/.corso/corso.env AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_SESSION_TOKEN AZURE_CLIENT_ID AZURE_TENANT_ID AZURE_CLIENT_SECRET CORSO_PASSPHRASE EOF

Initialize the Corso Repository

export CORSO_PASSPHRASE="CHANGE-ME-THIS-IS-INSECURE" docker run --env-file $HOME/.corso/corso.env \ --volume $HOME/.corso:/app/corso ghcr.io/alcionai/corso:${Version()} \ repo init s3 --bucket corso-test` }

Create your first backup

Corso can do much more, but you can start by creating a backup of your Exchange mailbox. If it has been a while since you initialized the Corso repository, you might need to connect to it again.

# Backup your inbox
.\corso backup create exchange --mailbox <your exchange email address>

# Backup your inbox
./corso backup create exchange --mailbox <your exchange email address>

{ # Backup your inbox docker run --env-file $HOME/.corso/corso.env \\ --volume $HOME/.corso:/app/corso ghcr.io/alcionai/corso:${Version()} \\ backup create exchange --mailbox <your exchange email address> }

:::note Your first backup may take some time if your mailbox is large. :::

There will be progress indicators as the backup and, on completion, you should see output similar to:

  Started At            ID                                    Status                Resource Owner
  2022-10-20T18:28:53Z  d8cd833a-fc63-4872-8981-de5c08e0661b  Completed (0 errors)  alice@contoso.com

Restore an email

Now, lets explore how you can restore data from one of your backups. You can see all Exchange backups available with the following command:

# List all Exchange backups
.\corso backup list exchange

# List all Exchange backups
./corso backup list exchange

{ # List all Exchange backups docker run --env-file $HOME/.corso/corso.env \\ --volume $HOME/.corso:/app/corso ghcr.io/alcionai/corso:${Version()} \\ backup list exchange }

  Started At            ID                                    Status                Resource Owner
  2022-10-20T18:28:53Z  d8cd833a-fc63-4872-8981-de5c08e0661b  Completed (0 errors)  alice@contoso.com
  2022-10-20T18:40:45Z  391ceeb3-b44d-4365-9a8e-8a8e1315b565  Completed (0 errors)  alice@contoso.com
  ...

Next, select one of the available backups and list all backed up emails. See here for more advanced filtering options.

# List emails in a selected backup
.\corso backup details exchange --backup <id of your selected backup> --email "*" | Select-Object -First 5

# List emails in a selected backup
./corso backup details exchange --backup <id of your selected backup> --email "*" | head

{ # List emails in a selected backup docker run --env-file $HOME/.corso/corso.env \\ --volume $HOME/.corso:/app/corso ghcr.io/alcionai/corso:${Version()} \\ backup details exchange --backup <id of your selected backup> --email "*" | head }

The output from the command above should display a list of any matching emails. Note the ID of the email you would like to use for testing restore.

  ID            Sender                 Subject                                  Received

  ...

To restore the selected email, use the following command.

# Restore a selected email
.\corso restore exchange --backup <id of your selected backup> --email <email ID>

# Restore a selected email
./corso restore exchange --backup <id of your selected backup> --email <email ID>

{ # Restore a selected email docker run --env-file $HOME/.corso/corso.env \\ --volume $HOME/.corso:/app/corso ghcr.io/alcionai/corso:${Version()} \\ restore exchange --backup <id of your selected backup> --email <email ID> }

A confirmation of the recovered email will be shown and the email will appear in a new mailbox folder named Corso_Restore_DD-MMM-YYYY_HH:MM:SS.

  ID            Sender                 Subject                                  Received
