So looking for some help.
I am trying to backup 1.5TB worth of ~11 million small files (2-20KB each) from my NAS to my new 2TB WD My Book Live. Confoundingly the MBL runs out of space before the NAS has finished backing-up.
The problem seems related to the huge number of small files that I work with on my NAS. These small files seem to expand in size and effectively fill the My Book Live!
Looking a bit deeper - SSH’ing ontop the MBL and using “du” - shows that these small files are effectively occupying 64KB of space each compared with the 4KB on the NAS. So I think this has somethink to do with Drive Block Size and the fact that the disks are significantly different in set-up. And therefore small files are very inefficiently store on the My Book for my particular use.
Is there anything I can do to reconfigure the block size on the My Book. As an alternative, I could ZIP together the files and backup the result but that takes an age and means I cant easily access a subset of old files when needed.
Any help/insight much appreciated.
Thanks.
