Supported browsers

Administrative UI supports the following browsers. We recommend that you use the most up-to-date browser that's compatible with your operating system.

• Chrome (latest version)

MariaDB

Storware Backup & Recovery server requires a MariaDB database server.

• Minimum supported MariaDB version: 10.6

• Latest supported MariaDB version: 10.11

We recommend installing MariaDB from the official repository.

If you need to install MariaDB packages without accessing an external repository during Storware Backup & Recovery installation you also can download RPMs and install them manually as described here

Hardware Requirements

Minimum requirements for all-in-one installation (Storware Backup & Recovery server and node on the same host):

• 64-bit 8 cores processor

• 10 GB RAM

• 20GB free disk space for the operating system and Storware Backup and Recovery installation

• Free disk space for data staging

  • You can estimate the free space requirement using the following equation: (Size of the biggest virtual machine) * (number of parallel backup threads)

Minimum requirements for Storware Backup & Recovery server (standalone installation):

• 64-bit 4 cores processor

• 4 GB RAM

• 20GB free disk space for the operating system and Storware Backup and Recovery installation

Minimum requirements for Storware Backup & Recovery node (standalone installation):

• 64-bit 4 cores processor

• 6 GB RAM

• 20GB free disk space for the operating system and Storware Backup and Recovery installation

• Free disk space for data staging

  • You can estimate the free space requirement using the following equation: (Size of the biggest virtual machine) * (number of parallel backup threads)

General network requirements

For detailed information about network requirements between Storware Backup and Recovery solution and supported platforms see Platform Requirements

Communication between node and server

Source	Destination	Ports	Description
Node	Server	443/tcp or 8181/tcp	Node <-> Server communication over HTTPS (port 443 or 8181)
Server	Node	111/tcp, 111/UDP, 2049/tcp, 2049/UDP, ports specified in /etc/sysconfig/nfs - variables MOUNTD_PORT (TCP and UDP), STATD_PORT (TCP and UDP), LOCKD_TCPPORT (TCP), LOCKD_UDPPORT (UDP)	NFS access to browse mountable backups and logs from administrative portal (using IP that is detected as the source IP - shown in the Node list in the portal)

Network consideration

• Depending on where the node is located you need to verify if data will not pass via low-bandwidth links.

• Access to the internet network from the node may be required in the following scenarios:

  • Installation, when using the external repositories

  • Backup and restore of Amazon EC2, Google Cloud Platform, Azure Cloud and M365

• Storware Backup & Recovery Node requires connectivity with backup destinations

• Storware Backup & Recovery Node needs connectivity with the Hypervisor or Hypervisor Manager.

• If a netcat transfer is used for Red Hat Virtuallization/oVirt/Oracle Linux VM/Proxmox VE/KVM stand-alone environments - 16000-16999 ports must be reachable from the hypervisors to the node which is responsible for those hypervisors.
