Recommended network infrastructure

A decade ago, the standard backbone infrastructure featured speeds of 100 megabits per second. Demands for network traffic and input and output have increased steadily and substantially. As a result, standards for network backbones have increased to meet demand. Modern network backbones support speeds such as gigabit Ethernet (GbE), which transfers Ethernet frames at 1 gigabit per second, or 10GbE, which is ten times faster.

For running Rapid Recovery, Dell requires a minimum network infrastructure of 1GbE for efficient performance. Dell recommends 10GbE networks for robust environments. 10GbE networks are also recommended when protecting servers featuring large volumes (5TB or higher).

If multiple network interface cards (NICs) are available on the Core machine that support NIC teaming (grouping several physical NICs into a single logical NIC), and if the switches on the network allow it, then using NIC teaming on the Core may provide extra performance. In such cases, teaming up spare network cards that support NIC teaming on any protected machines, when possible, may also increase overall performance.

If the core uses iSCSI or Network Attached Storage (NAS), Dell recommends using separate NIC cards for storage and network traffic, respectively.

Use network cables with the appropriate rating to obtain the expected bandwidth. Dell recommends testing your network performance regularly and adjusting your hardware accordingly.

These suggestions are based on typical networking needs of a network infrastructure to support all business operations, in addition to the backup, replication, and recovery capabilities Rapid Recovery provides.

UEFI and ReFS support

Unified Extensible Firmware Interface (UEFI) is a replacement for Basic Input/Output System (BIOS). UEFI is used in the Windows 8, Windows 8.1, Windows 10, Windows Server® 2012, and Windows Server 2012 R2 operating systems. For Windows systems, UEFI uses the Extensible Firmware Interface (EFI) system partitions that are handled as simple FAT32 volumes. Protection and recovery capabilities are available in Rapid Recovery for EFI system partitions.

Rapid Recovery also supports the protection and recovery of Resilient File System (ReFS) volumes for Windows Server 2012 and 2012 R2 .

Rapid Recovery also supports UEFI for protected machines with the Linux® distributions we support. These include Red Hat® Enterprise Linux® (RHEL®), CentOS™, Debian ®, Ubuntu®, SUSE® Enterprise Linux (SLES®), and Oracle® Linux.

Support for dynamic and basic volumes

Rapid Recovery supports taking snapshots of all dynamic and basic volumes. Rapid Recovery also supports exporting simple dynamic volumes that are on a single physical disk. As their name implies, simple dynamic volumes are not striped, mirrored, spanned, or RAID volumes.

The behavior for virtual export of dynamic disks differs, based on whether the volume you want to export is protected by the Rapid Recovery Agent software, or is a VM using agentless protection. This is because non-simple or complex dynamic volumes have arbitrary disk geometries that cannot be fully interpreted by the Rapid Recovery Agent.

When you try to export a complex dynamic disk from a machine with the Rapid Recovery Agent software, a notification appears in the user interface to alert you that exports are limited and restricted to simple dynamic volumes. If you attempt to export anything other than a simple dynamic volume with the Rapid Recovery Agent, the export job fails.

In contrast, dynamic volumes for VMs you protect agentlessly are supported for protection, virtual export, restoring data, and BMR, and for repository storage, with some important restrictions. For example:

  • Protection: In the case when a dynamic volume spans multiple disks, you must protect those disks together to maintain the integrity of the volume.
  • Virtual export: You can export complex dynamic volumes such as striped, mirrored, spanned, or RAID volumes from an ESXi host using agentless protection.

    However, the volumes are exported at the disk level, with no volume parsing. For example, if exporting a dynamic volume spanned across two disks, the export will include two distinct disk volumes.

    When exporting a dynamic volume that spans multiple disks, you must export the dynamic disks with the original system volumes to preserve the disk types.
  • Restoring data: When restoring a dynamic volume that spans multiple disks, you must restore the dynamic disks with the original system volumes to preserve the disk types. If you restore only one disk, you will break the disk configuration.

Repository storage: Additionally, Rapid Recovery supports the creation of repositories on complex dynamic volumes (striped, mirrored, spanned, or RAID). The file system of the machine hosting the repository must be NTFS or ReFS.

Support for cluster shared volumes

In Rapid Recovery release 6.x, as in AppAssure release 5.4.x, support for cluster-shared volumes (CSV) is limited to native backup of CSVs running Windows Server 2008 R2. You can also restore CSV volumes running Windows Server 2008 R2 from a recovery point, or perform virtual export to a Hyper-V CSV running Windows Server 2008 R2. You cannot perform virtual export of a cluster-shared volume. New as of Rapid Recovery release 6.0 is the ability to perform virtual export to a Hyper-V CSV running Windows Server 2012 or Windows Server 2012 R2.

For other operating systems, the Rapid Recovery Agent service can be run on all nodes in a cluster, and the cluster can be protected as a cluster within the Rapid Recovery Core; however, CSVs do not display in the Core Console and are not available for protection. All local disks (such as the operating system volume) are available for protection.

The following table depicts current support in Rapid Recovery core for cluster-shared volumes.

Table 1. AppAssure and Rapid Recovery support for cluster-shared volumes
Rapid Recovery Cluster Shared Volumes Support Protect, Replicate, Rollup, Mount, Archive Restore CSV Volumes Virtual Export to 
Hyper-V CSV
Rapid Recovery or AppAssure version 5.3 5.4 6.0 5.3 5.4 6.0 5.3 5.4 6.0
Windows Server 2008 R2 No Yes Yes No Yes Yes No Yes Yes
Windows Server 2012 No No No No No No No No Yes
Windows Server 2012 R2 No No No No No No No No Yes

While Rapid Recovery may let you protect some other operating systems on cluster-shared volumes, you do so at your own risk. Only the configurations in the table above are supported by Dell.
