 The /dev to be backed up has:
 
 crw-r-----  1 root  operator   24,  524289 Mar 22  2017 rsd0j
 crw-r-----  1 root  operator   24,  524290 Mar 22  2017 rsd0k
 crw-r-----  1 root  operator   24,  524291 Mar 22  2017 rsd0l
 
 which on amd64 maps to some rmd:
 
 crw-r-----  1 root    operator   24,       3 Oct 12  2019 rmd0
 crw-r-----  1 root    operator   24,       0 Jul 18  2011 rmd0a
 crw-r-----  1 root    operator   24,       3 Jul 18  2011 rmd0d
 crw-r-----  1 root    operator   24,      19 Oct 12  2019 rmd1
 crw-r-----  1 root    operator   24,      16 Jul 18  2011 rmd1a
 crw-r-----  1 root    operator   24,      19 Jul 18  2011 rmd1d
 
 ... and of course the currently running kernel has no md(4) at all.
