XFS filesystem can be backed up on Linux hosts using xfsdump.
Below are steps.

dnf -y install xfsdump
Backup the xfs filesystem using below xfsdump command.
xfsdump -f <filename>.dump <xfs filesystem to backup>
For example if you want to backup /var/lib/containers XFS filesystem and save the dump to /apps/images.dump, your command will look as follows:
xfsdump -f /apps/images.dump /var/lib/containers
