you want to retain the posix permissions. emcopy is smb - based thus it will validate ACLs and tries to copy them.  SID:S-1-5-18-1 means it is "local System" a well known SID and -213 is your owner from the source  if you want to stay on posix perms you should copy using i.e. rsync or (as you do) isi_vol_copy_vnx
If I run an isi_vol_copy_vnx, all permissions look good, but if I leverage emcopy to do a quick incremental copy, the owner and group are changed, even when the /nosec option is used.  Is there a way to leverage emcopy and have newly added files copied with the same permissions as isi_vol_copy_vnx?  isi_vol_copy_vnx permission OWNER: user:213 GROUP: group:203  emcopy permission with /nosec OWNER: user:root GROUP: group:wheel  emcopy permission with /secforce OWNER: SID:S-1-5-18-1-213 GROUP: SID:-S-1-5-18-1-203  Thanks for any input
emcopy changes owner and group security settings on bimodal data
