Network interfaces are missing in the StarWind Console

This article provides explanation why NICs might be missing from StarWind Console Configuration tab

Symptoms

During HA configuration on the step of choosing Sync and Heartbeat channels all IPs are missing. All IPs are missing in StarWind Console Configuration tab as well.

Cause

Network interfaces might be missing because of a third party app installed that uses port 3260. The most common app is MS iSCSI Target Server which can be accidentally installed along with File and Storage Services pack.

Resolution

MS iSCSI Target Server can be uninstalled via Server Management Console > Manage > Remove Roles and Features > Server Roles > iSCSI Target Server.

Any other software that uses port 3260 should be uninstalled as well.

After this StarWind service must be restarted.

3-2-1 Backup Rule or 3-2-1 Backup Plan

This article provides explanation why it is so important to have backups.

Purpose

The 3-2-1 backup rule can help you overcome nearly any failure scenario if you follow it.

Explanation

The 3-2-1 backup plan implies that you should:

1. Have at least 3 copies of your data

Having three copies of data means that the first one would be your actual data, wherever they reside.

The other replicas will provide for high availability and redundancy, since the more replicas you have, the more chances to keep the data safe.

2. Keep these backups on 2 different media

You should keep the data in 2 different formats, for one format outlives the other. For example, disks from the same RAID are statistically dependent, and often, after one disk failure, you might experience the failure of another disk from the same storage in a short period (often because the devices were bought approximately at the same time and from the same vendor). Using different formats reduces the risks that all your backups will be damaged, as different formats have different strengths and weaknesses when it comes to redundancy. Among the formats are: hard drive, tape library, DVD disks.

3. Store 1 backup offsite

It is understandable that a big disaster like an earthquake, fire or another unpleasant event will destroy buildings, and even datacenters may burn down resulting in powerful data loss. It is the reason why considering offsite data backups comes into view.

Offsite means as FAR AWAY as possible, in another city, state, country or even continent. Your data is safe then, even if there is a fire or national disaster.

There are many ways and solutions (like VEEAM backup, StarWind async replication, VTL, etc.) to accomplish this 3-aspect task, be they software or hardware. Backup process should be set as far from manual interaction as possible to avoid human error.
It is highly recommended to run backup jobs on a regular basis and scale (weekly, monthly backups, etc.) to be able to restore from the most recent and consistent one.
