Backup Agents

Agents do not require any open ports for regular backup and restore functionality. Optionally, open

the following ports for remote installation and remote access via the command line:

 TCP 445, 25001, 9876 (Remote installation for U1 and earlier, for communication with the

Storage Node)

TCP 445, 25001, 43234 (Remote installation for U2 and later)

 TCP 9850 (Access via the remote command line acrocmd)

 TCP 44445, 443 (for backup to the cloud)

 TCP 9877 (for mini-plans)

Storage Node

The Storage Node requires the following incoming ports to be open for communication with agents:

 TCP 9876, 9852

The following ports need to be opened for communication with the Catalog, if it is installed

separately:

 TCP 9876

Catalog

If the Catalog is installed separately, it needs to be able to accept incoming connections from all

Storage Nodes on the following port:

 TCP 9200

Outgoing WAN connections

If you are using Acronis cloud functionality, the firewall has to allow outgoing connections to the

following ports:

 TCP 80 (download installation files from UI)

 TCP 443 (sync licenses with account.acronis.com – this is required for subscription licenses)

 TCP 443, 8443, 44445, 5060 (create backups to Acronis cloud storage)

Third party components

Acronis products need to communicate with outside components for certain functionality. For

example, your SMTP server must accept connections from the Management Server in order to make

use of the email notification functionality. This section lists the most commonly used components

and their ports:

 VMware: TCP 443, 902 (need to be open for all connections from Acronis components that

communicate with vSphere/ESX)

 SMTP: Default ports include TCP 25, 465, 587, etc (from AMS to mail server, value can vary)

 NFS: TCP, UDP 111 and 2049 (from agents to NFS host)

 SMB: UDP 137, UDP 138 and TCP 139, TCP 445 (from agents to SMB share)

 SFTP: default TCP 22 (can vary depending on your server configuration)
