† Red Hat 7 Family Note
RecoverEDGE is not currently supported for disks created using the System Storage Manager (SSM) on the Red Hat, CentOS, Scientific Linux, and Oracle Linux Server 7 and later families.
UEFI is supported with BackupEDGE 03.02.00 and later. See the UEFI Support Tables for UEFI support information.
Oracle Linux Server 8.2 uses the Linux 4.x kernel in standard mode, and the Linux 5.x kernel in Unbreakable Kernel mode. However, you must install the Linux 4.x kernel distribution of BackupEDGE (edgelx40_64) for use with this operating system.
Oracle Linux Server 7.x, 8.0 and 8.1 can use the Red Hat kernel or the Unbreakable Kernel. You must choose the correct in-use kernel when making RecoverEDGE media.
- RecoverEDGE currently supports true hardware RAID on most platforms.
- MD RAID may be configured at any level, for any number of hard drives. Spare drives are not currently supported.
- DMRAID is not supported.
In many cases, if you run the operating system auto updater, such as "yum 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 7.7. 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.
RecoverEDGE releases prior to 03.02.00 supported BIOS mode only. See the UEFI Support Tables for UEFI support information.
Trusted Boot is not currently supported. Operating systems with Support Level 1 or Support Level 2 automatically become Support Level 3 when using Trusted Boot.
RecoverEDGE releases prior to 03.01.04 supported FDISK partitions only. See our GPT Support Table for a list of operating systems currently supporting GPT in RecoverEDGE.
RecoverEDGE bare metal disaster recovery currently supports the LVM2 volume manager under 2.6 and later kernels for backup and disaster recovery.
IPV6 networking is not supported; only IPV4.
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 Ubuntu Linux, then download the latest and greatest kernel from www.kernel.org and install it, two things would occur. One, you are no longer really running Ubuntu Linux, and two, it is unlikely RecoverEDGE would still function. Please limit your updates to those provided by the vendor.
Kernel Switches and Updates outside of normal updaters
BackupEDGE release are tested with standard operating system distributions and updates and normal security and application updates provided through updaters such as via "yum update". If you install a third-party kernel, or even a kernel from the OS vendor that was packaged and delivered outside the update / upgrade process, it won't have been tested and your product may no longer work with RecoverEDGE. If you choose to do this your license will be re-classified into Support Level 3.
