At the Coveware blog<\/a>, a few days ago, an interesting post was published. It covers the Nitrogen ransomware targeting VMware ESXi servers, but with an unexpected twist: the malware has a critical bug that makes decryption impossible.<\/p>\n\n\n\n

Even paying the ransom won\u2019t restore access, because the encryption keys are broken. This unusual case highlights just how crucial it is to have valid, tested backups. At the end of the day, this is a stark reminder: backups are your last line of defense, and without them, no ransom can save your data.<\/p>\n\n\n\n

Veeam Backup & Replication Essentials & Veeam Software Appliance<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n

One detail that is easy to overlook – but still relevant in practice – concerns the use of the Veeam Backup & Replication Essentials<\/strong> license.<\/p>\n\n\n\n

When this license is in place, it is indeed possible to deploy the Veeam Software Appliance<\/strong>, which can be a convenient and efficient option for many environments. However, there is an important limitation to be aware of: at least at the moment, the Veeam Software Appliance may not be deployed on physical hardware when using the Essentials license<\/strong>. Its use is supported to virtual deployments only<\/strong>.<\/p>\n\n\n\n

With the release of Veeam Backup & Replication 13<\/strong>, High Availability for the Veeam Software Appliance (Veeam HA)<\/strong> was introduced, enabling failover of the primary backup server node.<\/p>\n\n\n\n

Less widely noted is that the Veeam ONE 13.0.1 update<\/strong> adds monitoring and alerts specifically for this feature.<\/p>\n\n\n\n

A broad set of alerts now covers failures and health degradations in the HA environment:<\/p>\n\n\n\n
