Can I create a mksysb system backup on my Linux server?

While there is no direct equivalent of AIX’s mksysb utility to create bootable recovery media built into Red Hat Enterprise Linux, there are a number of commercial and open-source packages available that will be able to create system image backups.

In the event of a catastrophic system failure, our standard procedure is to perform a clean installation of the OS, install all updates, restore OS configuration files, and restore the database. While typically not as fast as an image-based restore, this process can be completed in a relatively short time (typically 2-4 hours), works on all any hardware, and ensures that your system is brought up to the latest build specifications.
