Cloud-to-Cloud Backup

Cloud-to-Cloud (C2C) backup protects your organization’s SaaS data — Microsoft 365 mailboxes, OneDrive files, SharePoint sites, and Google Workspace Drive content. C2C uses delta sync for incremental updates, so only changes since the last backup are transferred.

Connecting Microsoft 365

Two authentication modes are available depending on your Breeze deployment:

Multi-tenant app (recommended)

If your Breeze instance has C2C_M365_CLIENT_ID and C2C_M365_CLIENT_SECRET configured, the one-click consent flow is available.

1. Go to the C2C section in Breeze.
2. Click Grant Access (or Connect Microsoft 365).
3. You’re redirected to Microsoft’s admin consent screen.
4. Sign in with a Microsoft 365 admin account and grant the requested permissions.
5. Microsoft redirects back to Breeze. The connection is created automatically.

Manual credentials

If the platform app isn’t configured, the connection wizard prompts you to register an Azure AD app manually.

1. In the Azure portal, register a new app and grant the required Graph API permissions.
2. In Breeze, open the C2C connection wizard.
3. Enter the Client ID, Client Secret, and Tenant ID from your Azure AD app.
4. Click Connect.

Connecting Google Workspace

Google Workspace backup requires a service account with domain-wide delegation.

1. In the Google Cloud Console, create a service account and enable domain-wide delegation.
2. In your Google Workspace admin console, authorize the service account’s client ID with the required scopes.
3. In Breeze, open the C2C connection wizard and select Google Workspace.
4. Upload the service account key file.
5. Click Connect.

Managing Connections

Once connected, your C2C connections appear in the connections list showing:

• Provider (Microsoft 365 or Google Workspace)
• Connection status
• Last sync time
• Number of accounts/sites backed up

Configuring Backup Scope

After connecting, create a backup configuration to define what gets backed up:

1. Click Add Backup Config in the C2C section.
2. Select the connection to use.
3. Choose what to include:
   • Mailboxes — select specific users or all users
   • OneDrive / Google Drive — file storage for selected users
   • SharePoint sites — select specific sites (Microsoft 365 only)
4. Set a sync schedule (how often to pull changes).
5. Click Save.

Running a Sync

Syncs run automatically on schedule. To trigger an immediate sync:

1. Find the backup configuration in the C2C list.
2. Click Run Now.
3. The sync job starts and appears in the backup job list.

C2C uses delta sync — only items that changed since the last sync are transferred. Initial syncs may take longer depending on the amount of data.

Restoring C2C Data

C2C snapshots can be browsed and restored the same way as device backups. Use the Snapshot Browser to navigate mailbox contents, files, or site data, then select what to restore.
