Immutable Backup is a Veeam Backup & Replication feature that protects against ransomware attacks by preventing malicious software from modifying or deleting backup data.
Immutable backup means that once data is written to a backup repository, it cannot be modified, overwritten, or deleted until a specified retention period has passed. This can prevent ransomware from corrupting or encrypting backup data because the malware cannot modify or delete the backup files.
To backup VMs, you must first create a backup job. The backup job specifies how, where, and when VM data should be backed up. A single job can process one or more virtual machines. Jobs can be started by hand or scheduled for a specific time.
This scenario is useful if you want to store backups on multiple external hard drives that you intend to move between locations. The drives that are rotated can be detachable USB or eSATA hard drives.
You can use network-attached storage (SMB or CIFS Shares) as backup repositories with Veeam Backup and Replication. A network-attached storage (NAS) device can be a shared folder on your computer or any other physical device accessed via the Server Message Block (SMB) protocol.
You can back up and restore the On-Premises physical machines running Windows operating systems. Backup agents are installed on each computer by Veeam Backup & Replication.
Veeam’s WAN acceleration technology optimizes data transfer to remote locations. It is explicitly designed for off-site backup copy and replication jobs. You must deploy a pair of WAN accelerators in your backup infrastructure to enable WAN acceleration and data deduplication technologies.
Off-Host Backup proxy servers will retrieve VM data from the source datastore, process it and transfer it to the destination. The off-host backup proxy removes unwanted overhead on the production Hyper-V host.
Veeam Backup & Replication can perform backup, replication, and file copy operations on Microsoft Hyper-V VMs whose discs are located on Microsoft SMB3 file shares.
Microsoft released Windows patches on the second Tuesday of every month. This procedure installs Microsoft Windows server patches for the production cluster servers without an outage.
There are many ways to rebuild the Hyper-V host, but I will show you how to rebuild a Microsoft Hyper-V host via Virtual Media. These screens captured were for Windows Server 2019, but not for Windows Server 2019 only. You can use Windows Server 2022 ISO image file too.
Vulnerability in this Veeam Backup & Replication component allows unauthorized users to obtain encrypted credentials stored in the configuration database. The vulnerability may lead to these unauthorized users gaining access to backup infrastructure hosts. The vulnerable process Veeam.Backup.Service.exe (TCP 9401 by default) allows unauthenticated users to request encrypted credentials.
Veeam releases new patches on March 7, which fixed this vulnerability. No Hosts restart is required after installing this patch.
There are many ways to rebuild the Hyper-V host, but I will show you how to rebuild a Microsoft Hyper-V host via Virtual Media Wizard. This process is also can use for other vendors’ machines, not for the dataOn host only.
There are many ways to rebuild the Hyper-V host, but I will show you how to rebuild a Microsoft Hyper-V host via PXE. This process is also can use for other vendors, not for the DataOn host only. It would be best to ask the host hardware vendor to send you the custom WIM image file before rebuilding it.
This procedure upgrades a Windows Server 2012 R2 generation Hyper-V virtual machine to Windows Server 2019 (2022) generation 2 Hyper-V virtual machine.
Veeam released Veeam Backup for Microsoft 365 v6 on March 9, 2022, there are lots of new features at this version included Self-Service Restore Portal, Backup copy to low-cost object storage… etc. the detail information as following link.
