At least 1 GB of RAM must remain free during normal operations of the production machine for install and backups to run.
You can download the latest version of the Datto Windows Agent from the Datto Downloads page.
Version numbers for all Datto Windows Agent endpoints protected by your Datto device appear on the appliance's Device Overview page, in the Local Agent Information field, under the Agent Version heading for each listed production machine.
For Windows XP & Windows Server 2003
The current version of the Datto Windows Agent is 2.0.9, with driver version 126.96.36.199. For release notes, refer to the Datto Windows Agent (DWA) 1.0 and 2.0: Release notes.
You can download this version of the agent software from the following link: Datto Windows Agent: Legacy Installer.
For Windows Vista, Windows Server 2008, and above
Version information for this platform of the Datto Windows Agent is available in the Datto Windows Agent (DWA) Version 2.1 and above: Release notes.
Update notes for all versions
The agent software also automatically updates itself when a new version becomes available, except when the release includes a driver update. Because a driver update requires an update and reboot of the host system, you will need to download and install these versions manually.
If your protected machine does not have regular internet access, you will need to check for and install updates manually.

Due to their mobile nature, Datto does not endorse or support backing up laptops. Laptops must be inside the LAN, and not on a wireless network, to perform backups promptly. Attempts to back up laptops are at your discretion. Due to the range of touchpad drivers, custom drivers, and hardware configurations available for both laptops and all-in-one workstations, restoration support for these platforms is 'best-effort' only.
The Datto Windows Agent can only back up volumes that are recognized by the Windows operating system as logical, stable volumes. It cannot back up mapped network drives, iSCSI targets not attached as a logical volume, or removable drives.
The Datto solution is capable of backing up multiple types of disk sector schemes. The process writes an image-based backup to a file that is 512 bytes per physical sector. While rare, some software that relies on advanced formats, such as 4K, may have issues with the sector size change. Datto recommends performing regular DR tests to ensure that all required applications function as expected in our virtualized environment.
The backup of deduplicated volumes is untested and may produce inconsistent results.
File restore of deduplicated volumes is not possible. The Datto Windows Agent, ShadowSnap Agent, and agentless backup solutions are capable of restoring deduplicated volumes through:
Datto recommends running the following checks on the system you are protecting before installing the Datto Windows Agent:
Run chkdsk to be sure that all RAIDs and individual disks report back as healthy. Perform necessary disk repairs before deploying any backup agent. Failure to do so may result in backing up corrupted systems and restoration failures.
While Datto can perform backups that are running disk defragmentation, be aware that this rearranges data at a block level, and larger backups will consequently result.
Run disk defragmentation before deployment of the agent.
VSS-aware disk defragmentation programs may allow for smaller backups but are optional.
Download Windows updates, service packs, and any other Microsoft provided updates. After installing these updates, reboot the server. When scheduling your deployment, remember that the 2nd Tuesday of every month is Microsoft's 'Patch Tuesday.'
Run a virus scan before you deploy the Datto backup solution to your production machine.
Check the target's system and application logs to see if there are any VSS or hardware errors.
Resolve any errors before attempting to install the agent.
Do not install the Datto Windows Agent on any system currently protected by the ShadowSnap Agent, even if the ShadowSnap Agent is not present. Installing the Datto Windows Agent will start a new backup chain for the protected system and will not continue your existing ShadowSnap chain
Before installing the Datto Windows Agent, disable or remove all other backup software from the production machine. When uninstalling, use a high-level program that eliminates all traces of the incompatible software, including registry keys, DLLs, and stray folders. These components can cause conflicts.
