This post might be interesting for anyone who scripts Veeam SureBackup in any form. In this case you probably use the script of Luca Dell’Oca: How can you test 1000 VMs with Veeam SureBackup? This script is great and works just fine! A limitation here is that it is not possible to change default timeouts for boot and application initialization. Honestly this was a limitation […]
Some time ago I had to investigate discrepancies in the space consumption of large Veeam scale-out repositories. Theoretically, about the same space should have been allocated. But in reality the difference was quite huge. In this post I show how to query backup job space on Veeam Repositories and how to find orphaned files with PowerShell. In the first part I show how to easily […]
Recently I had to change DNS server in a VMware vSphere vCenter Appliance (VCSA). Normally this works without further issues. This time it was different. vCenter services did not start after changing DNS servers. I describe in this short post what went wrong and how I could fixed it.
The question keeps coming up, so I thought it is interesting to share: Is it possible to copy a backup copy job in Veeam Backup & Replication? So can a backup copy job use a backup copy job as source job? Yes and no. It is not possible to select the copy backup job directly. But it is possible to select the repository, the (second) copy […]
This post is about a feature of the Veeam Hardened Repository. It is about the ability to extend the immutable time of existing restore points. Veeam made this possible by using PowerShell. See here how to change expiration date of restore points in Veeam Hardened Repository and what’s new in v11a.
Each time I talk to customers at installation dates or health-checks, I spend some time talking about vSphere transport modes. These are: Direct Storage Access, Storage Integration (I take this as a separate mode), Virtual Appliance and Network mode. This is a topic with a lot of facets still not widely known. This comparison of vSphere transport modes is based on a few characteristics. I give some detailed information for Veeam […]
In this post I investigate what happens when a VMware vSphere ESXi host loses its boot device. This device is meant to be a persistent device. For non-persistent devices like USB- and SD-card, behavior is quite clear: whole ESXi OS runs in memory, no mass-write operations should be directed to the device. When it breaks, ESXi isn’t missing it and keeps running.
Backups of VMware vSphere VMs can be done with one of three transport modes. Each of these modes also provide the possibility to restore data. This post is about 3 reasons why direct SAN restore failover to NBD with Veeam Backup&Replication (VBR).
If you are working with Brocade respectively Broadcom Fibre Channel (FC) switches, you have probably had similar experiences as I have. Normally switches are running without any issues after setup. Sometimes firmware needs to be updated and zoning needs to be extended. Otherwise they just run. Last week I had the opposite experience. I saw very strange behavior caused by a full root partition on […]
