You can use the Veeam Backup & Replication console to restore individual files and folders from Veeam Agent backups. The procedure of file-level restore from a Veeam Agent backup practically does not differ from the same procedure for a VM backup. The difference is that you select a Veeam Agent backup instead of a VM backup in the File Level Restore wizard. To learn more, see the Guest OS File Recovery section in the Veeam Backup & Replication User Guide.
To restore files and folders from a backup of a Linux machine, you must have a VMware vSphere or Microsoft Hyper-V virtualization host added to the Veeam backup infrastructure. When you start the file-level restore procedure, Veeam Backup & Replication will use this host to deploy a helper appliance — a helper VM required to mount Linux machine disks from the backup. To learn more about adding a virtualization server, see Adding VMware vSphere Servers and Adding Microsoft Hyper-V Servers.
