If I backup both VMWare ESX host side and guest OS side, will files that are backed up from the guest side be de-duplicated when you backup the VMDK file from the host side?Dakota Backup de-duplicates at the block level. Since all the guest OS files appear as one large VMDK file from the host side, individual files backed up from the guest side will not be de-duplicated within the VMDK file. However, if the same file was stored in multiple different directories on the guest side, these would appear as repeating blocks within the VMDK file and these blocks would be de-duplicated.
