Cloud Continuity for PCs: Getting started



This article describes system requirements for the Datto Cloud Continuity for PCs Agent.


  • Datto Cloud Continuity for PCs
  • Windows 10
  • Windows 7


System requirements   

  • Windows 10 (all 64-bit versions)
  • Windows 7 (all 64-bit versions)
  • Latest updates and service packs should be installed
  • The Cloud Continuity Agent is only capable of backing up the protected system's Operating System (OS) volume. The Agent cannot back up other drives.
  • The OS volume must be 1 TB or less in size. Bare Metal Restore functionality requires smaller volumes. See the Warnings section below.
Memory requirements
  • At least 1 GB of free RAM on the production machine
Disk space requirements
  • The protected OS volume must have a minimum of 1 GB of free space at all times for continued Cloud Continuity functionality.
  • Cloud Continuity for PCs requires a minimum of 10% free space on volumes that are less than 100 GB in size.
  • Volumes that are 100 GB or larger require 10 GB of free space.
Volume Size Space Required Example
Less than 100 GB 10% of the volume* 80 GB = 8 GB
100 GB and above 10 GB* 1.5 TB = 10 GB
  • Port 443 on the protected machine must be open outbound.

    • Additionally, port 993, 80, or 587 on the protected machine must be open outbound. Only one of these three ports is necessary; the agent will try all three when attempting to connect to the cloud storage node.

    • The agent will use a TLS-based proprietary protocol for communication over the first port that it can reach.
  • The Cloud Continuity Agent's installer will attempt to create an outbound firewall exception for outbound traffic on ports 443, 993, 80, and 587 for the agent's executable (%SYSTEMROOT%\Program Files\Datto\Datto Cloud Continuity\DattoCloudContinuity.exe).
Anti-virus exceptions Create exceptions for Datto Cloud Continuity Service and the DattoProvider service.


For the latest Cloud Continuity Agent version information, see Cloud Continuity for PCs: Release Notes. You can check your protected machine's installed version from the agent tray icon. The Cloud Continuity Agent's latest release is always available at


The Cloud Continuity Agent lets you back up protected Windows 10, and Windows 7 systems' OS drives directly to the Datto Cloud without using a SIRIS, ALTO, or NAS appliance.

Datto designed Cloud Continuity to be mobile and agile. If your protected machine loses connectivity to the Internet or shuts down in the middle of a backup, Cloud Continuity's intelligent agent software will resume the backup where it left off when the system restarts or reconnects.

File restore, virtualization, Rapid Rollback, and Bare Metal Restore are available with the Cloud Continuity Agent. You can restore from any snapshot.


  • The Cloud Continuity Agent can only back up hard drives that are physically attached to the protected machine. The Cloud Continuity Agent cannot back up mapped drives.
  • Cloud Continuity is not for installation or use on systems already protected by the ShadowSnap Agent or the Datto Windows Agent. If your protected endpoint currently uses one of these backup solutions, do not switch to the Cloud Continuity Agent.
  • You do not need to reboot the protected system to start a backup, but snapshotting will not begin until the system reboots.
  • In the event of a Bare Metal Restore disaster recovery scenario, The disk you are restoring to must be larger than the original disk.  See Cloud Continuity for PCs: Bare Metal Restore: Performing the restore for more information.
  • GDPR Compliance Notice: During the agent registration process, you will have the option to select either the United States, Canada, or the United Kingdom to host your offsite data. Additional regional data centers will be available in future releases.
Cloud Continuity virtualizations automatically power off after seven days but remain mounted. If you need your virtualization running longer, you will need to power it back on every seven days.

  • Before installing the Cloud Continuity Agent, verify that no other backup software is present on the protected machine and that any VSS providers left behind by the prior installation of backup software are no longer present. Ensure that the target machine is in good health. It is critical to run a virus scan, disk defragmentation, and a disk health check (chkdsk /r) on the system before installation. Be sure to remove Microsoft Volume ShadowCopies as well.
  • The agent software will install the Datto Cloud Continuity Service and the DattoProvider service on the protected machine during this process. 
  • Datto recommends reviewing the Encryption Compatibility With The Datto Solution Knowledge Base article when deploying the agent to encrypted machines.

Frequently asked questions

Can I back up my machine with both a SIRIS and the Cloud Continuity Agent at the same time?

No. You can only use one type of backup solution at a time. Attempting to protect your machine with more than one kind of solution simultaneously can cause conflicts and backup failures.

What is the retention policy for my Cloud Continuity offsite backups?

We currently offer 1-year Time-Based Retention (TBR). Under the time-based retention model, your Cloud Continuity agents will:

  • keep all intra-daily backups for seven days
  • after that, keep daily backups for the next week
  • after that, keep weekly backups for the next month
  • keep the remaining backups for one year

To learn more about retention, see our Understanding the Retention Process article. For further information about Time-Based Retention (TBR), including pricing details, contact your Datto Sales Executive.

Are RoundTrips available for Cloud Continuity products?

Unlike Datto BCDR products, RoundTrips and Reverse RoundTrips are not available for Cloud Continuity.

Can I delete individual backups?

Yes, with the assistance of Datto Technical Support. See Cloud Continuity: Deleting Individual Backups for more information.

Can I set a custom backup schedule for my Cloud Continuity backups?

The Cloud Continuity Agent backs up your protected endpoint once every two hours. The schedule is not customizable.

Can I configure Advanced Backup Verification (including Screenshot Verification) for the Cloud Continuity Agent, and view the results?

Cloud Continuity backups cannot perform Advanced Backup Verification tasks at this time, but basic screenshot verification is available. See Cloud Continuity: Screenshot Verification Overview for more information.

Can I configure the Cloud Continuity Agent to alert me when a backup has failed?

Not at this time. However, specific email alert settings are available, and you can use the Cloud Continuity Status page to see if one or more backups completed on a given day.
