Backing up a 2.x MDT (or OST) is described in manual for:

 file level (MDT only supported since 2.3):
https://build.hpdd.intel.com/job/lustre-manual/lastSuccessfulBuild/artifact/lustre_manual.xhtml#dbdoclet.50438207_21638


 device level:
https://build.hpdd.intel.com/job/lustre-manual/lastSuccessfulBuild/artifact/lustre_manual.xhtml#dbdoclet.50438207_71633


I, personally, think it does an OK job of describing the limitations of
file and device backups - but there is always room for improvement:
