Proxmox: configure High Availability (HA) The Proxmox High Availability cluster feature allows to automatically migrate VMs to another cluster member node if the node where the VMs runs goes down. This feature guarantees the maximum VM availability reducing the downtime of the VM in case the node on which the VM is running fails. To configure HA, you need a working Proxmox cluster.   Create a Virtual Machine To test High Availability we need to have one or more VMs running in the Proxmox cluster. To create a new VM, right click a Proxmox node and select Create VM. Assign a VM Name and ..read more

Veeam v12: fix repository time shift detected During the Backup Job operation to a Hardened Repository, Veeam displays the warning "repository time shift detected" and the immutable flag is not applied to backup data.

Slow backup... are we using the right configuration? If you have a slow backup, the backup operation for the configured machines and applications may not be completed within the so-called backup window leaving dangerous time gaps in the backup strategy.

Create a Proxmox cluster Compared to VMware, to create a Proxmox cluster you don't need a dedicated appliance to centralize the management of resources such as CPU, RAM, storage and networking. The cluster is at the node level and can be managed by any node since it is a multimaster cluster (no master-slave nodes). To ensure a consistent configuration across all cluster nodes (the cluster configuration is distributed to all nodes), Proxmox uses a quorum-based voting mechanism leveraging the Corosync cluster engine.   Create a Proxmox cluster To create a Proxmox cluster you need two or mo ..read more
