  1. [ Blog ] How to Object First

    If the OOTBI repository used for Veeam backups is out of space, you can expand Object First OOTBI cluster with a simple, secure, and seamless procedure.

    The process of adding new nodes to your cluster is straightforward allowing you to go from a single node to a multi-node powerhouse in just a few simple steps.

    In this example, an rviv.ly/kfFLR5

  2. I'm back to a three-node #Proxmox cluster. With replications and high availability configured, this setup is my favorite because I can turn off my power-hungry #DIYNAS and my critical #homelab services will still be online, distributed among the rest of the nodes. Also, this cluster will survive a random single-node failure, so I'll be less worried about the #homelab while away.

    Price is an additional 10-15 watts of power consumption.

  3. [ Blog ] How to configure the Veeam High Availability - pt.1

    Veeam & Replication v13 introduces the High Availability Cluster, which allows you to keep the backup infrastructure alive in case one Backup fails.

    Before proceeding with the configuration, it is important to be aware of the limitations of the HA cluster.

    To Proxmox cluster and prevent data loss or corruption, especially when Ceph storage is in use, you must follow a specific procedure.

    Explanation:
    This big beautiful spiral shines in X-ray light. It is about 20 times larger than our Galaxy. It belongs to Abell 2029, a galaxy cluster one billion light-years away. To see only the galaxies, look at the image to the right.
    Galaxy clusters are the largest structures in the universe that are supported by gravity. Abell 2029 is formed by thousands of galaxies, surrounded by a huge cloud of hot gas and the equivalent of more than a trillion times the mass of the Sun in dark matter. The spiral is made of gas, mostly hydrogen and helium, heated to millions of degrees. It was found in a recent study that used data from NASA's Chandra X-ray Observatory to show that Abell 2029 had a collision with a smaller cluster four billion years ago. The collision affected the gravitational field and caused the intracluster gas to slosh, like wine moving in a wine glass, shaping the spiral.
