The DDBoost plugin has a dependency on the version of libc library. 
Before version 1.23.0 some versions require libc version 2.14 or above.
Version 1.23 and above have been created requiring libc 2.12 or above.

The OS RHEL 6.x may only have libc version 2.12. 

Environment

Product Version: 5.28

Resolution

Fix
Issue is fixed in gpbackup 1.23.0 and above.
