VEEAM BACKUPS LICENSE
If you are using the Enterprise or Enterprise Plus license edition in your virtual environment, consider that Veeam Backup Enterprise Manager keeps index files for backups that are currently stored on disk, and for archived backups (for example, backups that were recorded to tape). Note that with the file browsing functionality, you can browse and search for files in the selected machine backup at a specific restore point only. After catalog replication, you can browse any machine backup for OS guest files.
