Linux Support - Red Hat Family - RecoverEDGE Notes

Operating System and Hardware Restrictions

UEFI is supported in 8.x and 7.x products. UEFI Secure Boot is not currently supported.

NVMe Storage is currently supported in the 8.x family.

IPV6 networking is not supported; only IPV4. As long as IPV4 is configured properly, it will be used. IPV6 may also be configured but will be ignored.

RecoverEDGE is not currently supported for disks created using the System Storage Manager (SSM) on the Red Hat Enterprise Linux, CentOS, Scientific Linux, and Oracle Linux Server 7 and later families.

The P2V feature of licensed copies of BackupEDGE is not supported with LVM; only with standard filesystems.

RAID Types

  • Hardware RAID is supported.
  • MD RAID is supported (8.x and 7.x families.See below.).
  • DMRAID is not supported.

MD RAID Support

RecoverEDGE supports MD RAID with the following caveats:

  • We do not support spare devices.
  • The MD structure may only contain a file system. No logical volumes or partitioning of the MD devices are permitted.
  • BackupEDGE release 03.04.01 build 1 is now the minimum required release for those using MD RAID.

In many cases, if you run the operating system auto updater, such as yum update (or dnf update), you'll end up with the equivalent of an entirely new release, which may not yet be supported by your current BackupEDGE release. For instance, run yum update on Red Hat Enterprise Linux 7.5 and it will essentially be upgraded to Red Hat Enterprise Linux 7.9. Make sure that:

  • you match and update BackupEDGE releases to those compatible with your Linux release.
  • you re-create your RecoverEDGE media or ISO images.

In some instances attempting to re-create RecoverEDGE images may fail after an operating system upgrade. Before calling technical support, download and update / upgrade to the latest BackupEDGE release listed as having support for your updated operating system release.

Bare metal disaster recovery, i.e. RecoverEDGE, requires an intimate knowledge of the base Linux operating system involved, the vendor supporting the operating system, and the updates and changes the vendor makes. Only authorized updates from the vendor relating to kernel and storage issues can be supported. For example, if you were to install Red Hat Enterprise Linux, then download the latest and greatest kernel from and install it, two things would occur. One, you are no longer really running a fully integrated Red Hat Enterprise Linux distribution, and two, it is unlikely RecoverEDGE would still function. Please limit your updates to those provided by the distribution vendor.
