Rapid Recovery 6.1.2 - Release Notes

Rapid Recovery system requirements

This section describes the system and license requirements for installing the Rapid Recovery Core, Rapid Recovery Agent, and Rapid Recovery Central Management Console.

Recommended network infrastructure

For running Rapid Recovery, Quest requires a minimum network infrastructure of 1 gigabit Ethernet (GbE) for efficient performance. Quest 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), Quest recommends using separate NIC cards for storage and network traffic, respectively.

Use network cables with the appropriate rating to obtain the expected bandwidth. Quest 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). 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 with the following operating systems:

Windows: Windows 8,Windows 8.1, Windows 10; Windows Server 2012, Windows Server 2012 R2, and Windows Server 2016.
Linux: All supported versions of Linux.

Rapid Recovery also supports the protection and recovery of Resilient File System (ReFS) volumes for Windows Server 2012, Windows Server 2012 R2, and Windows Server 2016.

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 or Hyper-V 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.
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.
