Reading Time: 5 minutesAs descrived in the previous post (Optimize the consumed space of the Veeam Backup Catalog) the Veeam Backup Catalog is a feature of Veeam Backup & Replication that stands for VM guest OS file indexing. It’s not a server role, but it’s a service of the Veeam Server, for this reason required space must be planned carefully. By default, the indexing data is stored in the VBRCatalog folder (C:\VBRCatalog) on the Backup Server.
