Hi folks,

we should make an effort to back up the test beam raw data to hpss. The 
data disks are somewhat the wild west with raw data files scattered all 
over private directories but you should be aware that your are just one 
catastrophic disk array failure away from loosing some or all of it. We 
stopped putting test beam files into hpss in 2017, I just backed up the 
TPC data from 2018 and 2019. Everything else - see the previous sentence.

Chris

P.S. reasons for catastrophic failure include loosing more then one disk 
in a lun before raid5 can recover (I remember that happening once) or a 
controller hardware error where it starts overwriting stuff (also 
happened once).
