Hello,

it seems rpm : Index of /pub/repos/yum/common/redhat/rhel-7.7-x86_64/pgbackrest-2.27-1.rhel7.x86_64.rpm

is not compiled with zstandard library.

This is a new feature from pgbackrest release 2.27

I have the following error message  when I try to backup :

ERROR: [032]: pgBackRest not compiled with zst support


Thank you.
