Getting Started with Datto Endpoint Backup with Disaster Recovery Linux Agent

Datto Endpoint Backup with Disaster Recovery Linux Agent supports the following 64-bit operating systems:

• Ubuntu 18.04 (4.15 and 5.4 kernels)
• Ubuntu 20.04 (4.15 and 5.4 kernels)
• Ubuntu 22.04 (5.15 kernel)

• Datto recommends a minimum of 2 CPU cores for the backup agent, depending on workloads. If the agent is experiencing high CPU usage during backups with fewer than 2 CPUs, the production machine may require additional resources.
• At least 1 GB of RAM must remain free during normal operations of the production machine for install and backups to run.

• Each protected volume must have 10% of its space free (up to 10 GB).
• Datto Endpoint Backup with Disaster Recovery supports adding up to seven Protected Systems, with up to six TB of disk space (total storage capacity) between them.
• VMs on per VM billing will instead be limited to 1 TB managed disk capacity per VM.

• 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.
• At a minimum, the protected machine must have internet access, and be able to resolve the following addresses for the initial installation and on-going operation of the Datto Linux Agent:
  https://device.dattobackup.com/certApi.php
  https://cpkg.datto.com
• The agent will use a TLS-based proprietary protocol for communication over the first port that it can reach.
• Port 3262 must be open outbound for Bare Metal Restore functionality.
• All protected machines must be able to resolve mothership.dtc.datto.com,agent-update.datto.com, dattolocal.net and valid-isrgrootx1.letsencrypt.org in the local DNS.
• See Unified Backup networking and bandwidth requirements for detailed network requirements and WAN uplink considerations.
