These days I investigated the possibility to export Veeam Backup&Replication (VBR) console job log programmatically with PowerShell. Read here how this can be done.

This post is about a new feature in Veeam Backup&Replication v11: Hardened Repository. This means immutable backups. It will massively increase security on repositories. Read here how it behaves.
This post is about a great new feature in Veeam Backup&Replication v11: Hardened Repository. This means immutable backups. It will massively increase security on repositories. With immutability enabled, root access is needed to delete or change backup files. Read here how it (just) works and how it behaves.
When backing up on XFS repositories for example with Veeam Backup&Replication, XFS feature reflink can be used for Fast Cloning. I wrote already a post about checking Microsoft ReFS space savings. Now I want to show some basics to check XFS savings too.
In this post I share a small PowerShell/PowerCLI script to check if VMs get backed up by Veeam B&R. If you do not run VeeamONE, it can be challenging to check if every VM that should be backed up, is really backed up. For checking this, this script should be helpful.
These days I had to troubleshoot poor VMware vSphere SAN transport mode performance during backup with Veeam. Before SAN mode, NDB transport mode was used. NBD outperformed SAN mode totally!
These days I had to troubleshoot a problem with system time within a VMware vSphere VM. During backup VM freezes for more than 30 seconds. When this happens, system time in VM also stops and resets to current time after the freeze. And this behavior causes massive problems in the application-layer. During troubleshooting we found a very slow VM snapshot deletion on NFS volumes on […]
This post shows three ways to analyse ReFS space savings with Block cloning. And because Veeam Backup&Replication uses this feature massively, I use this backup solution as an example here.
An interesting question arose some time ago. A customer changed permissions of files on a Windows file-server VM. Changes were replicated using DFS. So far so good, but the amount of data that was processed at next incremental backup of target VM was even more than a full backup. Because incremental backup is based on VMware Changed Block Tracking (CBT) feature, it was suddenly interesting […]
