If you do this then the max number will be 3 backups - this because the 4TB drive is not actually giving you the full size of 4TB.įor example, I could not do a sector-by-sector backup of a 4-TB drive to another 4-TB drive. Question: why do you want to make sector-by-sector mode backups including unallocated space? This is not needed for any normal Backup & Recovery operation and will cancel out any compression and exclusions set for the task, so the backup size will be the disk size, i.e. If I have a 1-TB internal hard-disk drive, and a 4-TB external hard-disk drive, how many sector-by-sector backups (including unallocated space) can I keep on the external hard-disk drive?
