SIRIS, ALTO, and NAS: Getting started with the Datto Mac Agent

Follow

Topic

This article describes system requirements for the Datto Mac Agent.

Environment

  • Datto Mac Agent 

Description 

System requirements   

OS Datto has tested the Mac Agent for compatibility with the following operating systems:
  • macOS version 10.10 (Yosemite)
  • macOS version 10.11 (El Capitan)
  • macOS version 10.12 (Sierra)
Hardware 

The macOS must be running on genuine Mac hardware. Attempting to back up a macOS install running in a non-native environment may produce unreliable results.

Disk permissions

The Mac must have disk permissions verified and repaired if necessary.

Disk space requirements Each volume that you wish to back up with the Datto Mac Agent must maintain free space equivalent to 10% of the total size of the volume or 3 GB, whichever number is smaller.
Network
  • The protected machine must have Internet access, and be able to reach https://device.dattobackup.com/certApi.php for the initial installation of the Datto Mac Agent
  • Your network must allow TCP port 25569 traffic between the Mac and Datto appliance.
  • Your network must allow port 3260 (TCP) inbound to the Datto appliance from the Datto Mac Agent.
  • If you have enabled local firewall rules, make sure there is an exception in place on the firewall for incoming connections to the Datto Mac Agent.
  • For in-depth networking requirements for Datto backup solutions, see our Datto Networking Requirements article.
Anti-virus exceptions Ensure that you have whitelisted the Datto Mac Agent in any antivirus solution you are running on the production machine.
Compatibility The compatibility of this backup solution with any hypervisor environment or operating system not listed in this article is untested and may yield unreliable results.

Versioning

See our Datto Mac Agent (DMA): Software Release Notes for versioning information. You can check your protected machine's installed version from the Protect tab of your Datto appliance's GUI. 

The agent software on the protected machine will periodically notify you when an update is available. You can also force an update check by clicking the Datto Mac Agent icon in the toolbar, and selecting Check for Updates, as shown in Figure 1.

When updating the Datto Mac Agent, a reboot of the production machine may be required. Datto recommends only performing updates during scheduled maintenance windows.

 Warnings

  • 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 wide 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.
  • Avoid using spaces in protected volume names (e.g., C:/Volumes/Server Backup instead of C:/Volumes/ServerBackup). Spaces may cause issues with mounting and unmounting file restores. 
  • If you purge data, you may experience large backups in macOS 10.12 (Sierra).
  • If you update a protected machine to macOS X to version 10.12.5 from an earlier version, you may need to force a new full backup of the agent for continued compatibility with the Bare Metal Restore process.
  • Datto's Mac Agent backs up macOS systems to Datto appliances. With the resulting backups, you can perform a File Restore or Bare Metal Restore to Apple hardware. Due to legal limitations, you cannot virtualize a Mac or restore to non-Apple hardware.
  • Datto does not support the Apple File System (AFPS) for file restores, so restored AFPS files will not properly inherit permissions. For assistance with Mac file restores, contact Datto Technical Support.
  • The Datto Mac Agent is not compatible with Fusion Drive and FileVault setups. It is possible to non-destructively turn off FileVault by following Apple's official guide (external link).
    • Because the Datto Mac Agent's driver sits at a level within the I/O stack that is above the encryption layer enabled by FileVault, the driver will see the disk contents as encrypted, making the Datto Copy-On-Write file inaccessible during the snapshot process. 
  • The Datto Mac agent does not support RAID configurations or the Apple File System (APFS). Also, the Mac Agent has known conflicts with DeepFreeze and Symantec Encryption Desktop for macOS X.

Installation

You can download the Datto Mac Agent at download.datto.com. Click the macOS icon in the Backup Agent Download category. Ensure you are installing the latest version of the Datto Mac Agent, and that it is in a healthy installation state. Follow the steps in the Installing the Datto Mac Agent article to deploy the agent to your production machine.
