Ports Open
KB 1711, Firewall settings for Acronis products, is an extensive description of the (complex) networking needs for interoperability of Acronis products.
Once you get past determining which exact product you have (is Acronis Backup 12.5 the same as Acronis Cyber Backup 12.5? the naming structure is terrible, way too similar), you get to the section you need to look into. For example, i[dot]imgur[dot]com[slash]P0VTjPE.png (can one post images in this forum system? no. can I post a link to an image, even after being a member for 7 years? no)
Note it states "TCP ports 443, 44445, and 55556 for backup to cloud", but there is also a "Acronis Backup Cloud, Acronis Backup 12.5 cloud deployment, Acronis Backup 12 cloud deployment" section below. Maybe backup to cloud should be entirely in it's own section?
Do I need to allow the ports for the acrocmd, acropsh cmds? I don't know if I am using these tools.
It is way too confusing for me (been using acronis products for over 10 years, and back up software for 20+). Imagine for a regular end user!
So bottom line, disregard all of the above if you will, but pls hear me out:
Feedback: make a port opening guide by use case. for example: I am backing up a Linux server and I only installed the linux agent. Which ports do I need to open on the linux machine to successfully manage it from another machine? Oh, you want to add remote installation/upgrade? Also open these ports.
Question: are you guys serious that for the use case above I need ALL of these open??445,5905,7780,7755,7756,7765,9852,9860,9862,9876,9877,25001,43234/tcp
Thank you

Hello Eddie,

As I can see, Peter has already answered your questions. Thus, I post some clarifications.
In order to add an image to the forums post, please click on the image icon:
Acronis Forum File Manager will be opened in a separate window. Please press Upload-> Add image, navigate to the respective file and then select it from the list.
Note it states "TCP ports 443, 44445, and 55556 for backup to cloud", but there is also a "Acronis Backup Cloud, Acronis Backup 12.5 cloud deployment, Acronis Backup 12 cloud deployment" section below. Maybe backup to cloud should be entirely in it's own section?
The cloud backup consoles in Acronis Cyber Backup 12.5 cloud deployment and Acronis Cyber Backup Cloud are based on Acronis Cyber Cloud platform, they use similar ports for accessing the backup console, registering the agents, downloading the certificates, user authorization, and downloading files from the cloud storage. That is why they are combined in one section in this article.

There is such KB article for Windows services and processes with their description (purposes) and respective ports (so you can decide which ports you would keep closed if you do not need a respective software component): https://kb.acronis.com/content/60085
However, thank you for your suggestion. We will update an existing KB article for Linux services (will add respective ports to each service, they are available in the documentation provided above by Peter): https://kb.acronis.com/content/60802

As I answered above, you can keep a port closed if you do not use a respective Acronis Cyber Backup component (e.g. Acronis Active Protection Service, Acronis Removable Storage Management Service, Acronis PXE Server, etc.)
