Red Hat Enterprise Linux 8 / 7 Family Notes
Linux server distributions are generally supported for finite periods of time, generally two to five years, by the developer releasing the product. BackupEDGE support may be limited, even under Subscription, after the operating system has reached the developer's official end-of-life.
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.
