Software requirements for VMware

This section lists the supported versions for VMware vCenter Server and ESXi Hosts.

Druva does not certify VMware vCenter Server version 5.5 and 5.1. However, backups and restores on these setups should work as expected.  Druva strongly recommends you to upgrade the VMware vCenter Server to the latest supported version. Refer to the article for more information about the end of the general support for vSphere 5.5.

Note: To backup virtual machines hosted on vCenter and ESXi versions 6.5, use backup proxy version 4.6.9-27415 or later.

Backup proxy compatibility

The following table describes the virtual machines backup support corresponding to backup proxy deployed on specific vCenter and ESXi versions:

Backup Proxy Version

Backup Proxy Compatibility

4.7.2-42700 or later

vCenter or ESXi versions:

  • 6.7
  • 6.5
  • 6.0
  • 5.5
  • 5.1

4.6.9-27415 to 4.7.2-42106

vCenter or ESXi versions:

  • 6.5
  • 6.0
  • 5.5
  • 5.1

Versions older than 4.6.8-20739

vCenter or ESXi versions:

  • 6.0
  • 5.5
  • 5.1

If a backup proxy is deployed on an incompatible vCenter or ESXi version, virtual machine backup jobs will fail. 

Guest operating systems

Phoenix qualifies virtual machines with the following guest operating systems for backup. However, any guest operating system should work if the virtual machine snapshot(VMware tools quiescing turned ON) works fine. 

Operating System

Editions

Windows

  • Windows Server 2012 R2 (64-bit) 
  • Windows Server 2012 (64-bit)
  • Windows Server 2008 R2 (64-bit) 
  • Windows Server 2008 (64-bit) 
  • Windows Server 2016 (64-bit)
Note: Phoenix performs image-level backups of virtual machines. So, unless you plan to enable application-aware processing for a virtual machine, Phoenix continues to back up the virtual machine with any guest operating system.

Linux

  • CentOS 6.3 - 6.4, 7.0 - 7.2 (64-bit)
  • Red Hat Enterprise Linux (RHEL)6.3 - 6.4, 7.0 - 7.2  (64-bit)

vSAN versions

Phoenix backup proxy supports backup and restore of virtual machines on the following vSAN versions:

  • 6.6
  • 6.5

Ports and communication protocols for Phoenix

Phoenix communicates with your virtual infrastructure to backup and restore virtual machine data. This communication happens via ports and communication protocols that are secure for communication and transition of data.

Phoenix uses a combination of Transport Layer Security (TLS) and Secure Socket Layer (SSL) protocols for establishing a connection and initiating communication between Phoenix components and your virtual infrastructure components such as vCenter Server, ESXi hosts, and virtual machines.

The following diagram depicts the ports and communication protocols that are used by Phoenix for secure connection and communication during the backup and restore operations.

port_communication_protocols_vmware_with_SQL.png

The following table describes the port and communication protocols used for communication between Phoenix and various VMware components.

Port

Communication Protocol

Description

443

HTTPS+SSL

Phoenix uses Port 443 to establish a secure connection and communication between the following:

  • Backup Proxy to Phoenix Cloud
  • Backup Proxy to Phoenix CloudCache
  • Backup Proxy to vCenter Server
  • Backup Proxy to ESXi host
    Note: Backup proxy establishes connection with ESXi host over Port 443 only if it registered with Phoenix as Standalone ESXi. If the ESXi host is registered with Phoenix through vCenter Server, backup proxy communicates with the ESXi host over Port 902.

902

TCP/UDP

Phoenix uses port 902 to establish a connection between the backup proxy and ESXi host registered with Phoenix through vCenter Server.

3542 HTTPS+SSL For application-aware backups, the backup proxy uses VMware Tools to inject two executables and a few supporting files such as certificates into the guest OS of the virtual machine. When the executables run, they start guest OS processes called guestossvc and PhoenixSQLGuestPlugin. The backup proxy uses the opened port 3542 on the guest OS so that it can communicate with guestossvc to run SQL Server backups. Ensure that this port is open on the guest OS.

The backup proxy also uses this port to restore databases to the virtual machine.
3545 HTTPS+SSL For application-aware backups, the SQL executable service PhoenixSQLGuestPlugin  queries the Microsoft VSS APIs to back up and restore SQL Server databases. The guestossvc service interacts with the PhoenixSQLGuestPlugin  service using this port. The PhoenixSQLGuestPlugin service cannot directly communicate with the backup proxy. 

3389/22

 

TCP/UDP

During the backup cycle, the backup proxy sends network packets to Windows virtual machines (where VMware tools are installed) on port 3389 to identify if the RDP port is open or not. For Linux virtual machines, the port is 22, which is used for SSH.

This is used for Phoenix DRaaS or DR restores.

123 UDP Backup proxy accesses NTP server on Port 123 (UDP) for time synchronization.

443

HTTPS+SSL

Phoenix uses SSL for a secure connection that happens between the following:

  • Backup proxy and vCenter Server
  • Backup proxy and ESXi hosts

443

HTTPS+TLS

Phoenix uses TLS for a secure connection that happens between the following:

  • Backup proxy and Phoenix Cloud
  • Backup proxy and Phoenix CloudCache
  • Phoenix CloudCache and Phoenix Cloud
