Backup storage |
This option applies to Unitrends virtual systems only. Backup storage can be increased by adding a virtual disk to the UEB virtual machine using the hypervisor. Note: Although it is possible to attach external storage directly to the UEB VM, this is not recommended. If you must connect to external storage from the UEB virtual machine directly through network protocols (NFS, CIFS, or iSCSI), be sure to use a supported vendor from the list in KB 1574. Once the storage is added in the hypervisor, go to the Unitrends system and either expand the existing backup device to include the new disk, or add a separate backup device. (See To expand a backup device or To add backup storage and create a new device for details). Within the hypervisor, you can add internal disks to the UEB VM or, if you deployed your UEB to an attached SAN or NAS storage array, you can create datastores (VMware) or volumes (Hyper-V) from that array to add virtual disks (VMDK or VHDX) to the UEB VM. Warning: It is strongly recommended that all UEB storage is either direct attached storage (DAS, internal to the hypervisor) or resides on one external storage array. If you configure storage across multiple storage arrays and one becomes unavailable, all backup data is corrupted, resulting in total data loss. You can leverage SAN or NAS storage to create datastores (VMware) or volumes (Hyper-V) by connecting the external array to the hypervisor host: • A SAN LUN on the array can be connected to the hypervisor host and exposed to UEB. You can then add the entire LUN to UEB or create virtual disks (VMDK or VHDX) on the LUN and expose these disks to UEB for added storage. • A NAS share can be connected to the hypervisor host over CIFS or NFS protocol to create virtual disks (VMDK or VHDX) for added storage. |
Vault storage |
This option applies to Unitrends virtual systems performing legacy vaulting only. Additional vault storage can be added to the virtual system in the following ways: • A SAN iSCSI LUN can be used • The Hypervisor can connect to a SAN using iSCSI or Fibre Channel and expose the LUN as a Raw Device Mapping device • An additional virtual disk can be added to the virtual system • A NFS NAS share can be leveraged. NAS shares configured with the CIFS protocol are not supported for legacy vaulting |
Archive storage |
This option applies to all physical and virtual systems that have been licensed for advanced archiving. Additional archive storage can be added in the following ways: • A SAN iSCSI LUN can be used • A NAS share configured with the CIFS or NFS protocols can be leveraged • For virtual systems, an additional virtual disk can be added • Cloud storage using the Unitrends CloudHook |
NAS protection |
This option applies to all physical and virtual systems. A NAS share configured using the NFS or CIFS protocol can be mounted directly on the system and protected as a client. |
Protect VMs on a SAN |
This option applies to Unitrends physical systems and UEB on VMware. This options is not available for UEB on Hyper-V. For VMware environments where datastores are hosted on a SAN, configure SAN storage so that data is backed up directly from the SAN to the backup system. For details, see VMware SAN-direct backups. |
