### NTFS File System Support

Windows file-level operations require the Storware Backup and Recovery Node to access NTFS file systems. This is needed when the node mounts backup data and allows users to browse, recover, or restore individual files from Windows volumes.

To perform these operations, the node operating system must provide NTFS support. In most Linux environments, this is provided by the `ntfs-3g` package or another compatible NTFS driver/module.

If NTFS support is not installed on the node, Windows File-Level Restore operations may not be available or may fail when accessing NTFS volumes.

### 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.

* Supported MariaDB versions: 10.11

We recommend installing MariaDB from the official [repository](https://mariadb.com/kb/en/mariadb-package-repository-setup-and-usage/).

{% hint style="info" %}
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](https://mariadb.com/kb/en/installing-mariadb-with-the-rpm-tool/)
{% endhint %}

## Hardware Requirements

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

* 64-bit, 8 processing cores
* 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 processing cores
* 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 processing cores
* 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)`

More detailed sizing can be found [here](/deployment/sizing.md).

## General network requirements

### Communication between the server and the node

| 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) |

### Subscription and telemetry

**Server requires Internet access** (on 443/TCP port) in order to enable subscription-based license model and send reports/logs to the support team.

If the Internet connectivity is restricted, then you need to allow traffic from the server to the fallback API endpoint: [fallback-api.cloud.storware.eu](http://fallback-api.cloud.storware.eu) (port 443/TCP)

### Network bandwidth

Make sure to use a high-bandwidth, dedicated network for data transfers:

* from the source to the node
* from the node to the backup destination of your choice

## Security Requirements

## User Permissions

User `vprotect` must be a member of the group "disk".

Sudo privileges are required for the following commands:

**Storware Backup & Recovery Node:**

* `/usr/bin/targetcli`
* `/usr/sbin/exportfs`
* `/usr/sbin/kpartx`
* `/usr/sbin/dmsetup`
* `/usr/bin/qemu-nbd`
* `/usr/bin/guestmount`
* `/usr/bin/fusermount`
* `/bin/mount`
* `/bin/umount`
* `/usr/sbin/parted`
* `/usr/sbin/nbd-client`
* `/usr/bin/tee`
* `/opt/vprotect/scripts/vs/privileged.sh`
* `/usr/bin/yum`
* `/usr/sbin/mkfs.xfs`
* `/usr/sbin/fstrim`
* `/usr/sbin/xfs_growfs`
* `/usr/bin/docker`
* `/usr/bin/rbd`
* `/usr/bin/chown`
* `/usr/sbin/nvme`
* `/bin/cp`
* `/sbin/depmod`
* `/usr/sbin/modprobe`
* `/bin/bash`
* `/usr/local/sbin/nbd-client`
* `/bin/make`

**Storware Backup & Recovery server:**

* `/opt/vprotect/scripts/application/vp_license.sh`
* `/bin/umount`
* `/bin/mount`

## SELinux

PERMISSIVE - currently, it interferes with the mountable backups (file-level restore) mechanism. Optionally can be changed to ENFORCING if the file-level restore is not required.
