Backups taking horrendous time - file size larger than original

W7 64 bit Ultimate    AMOEI Backupper Standard 2

Backing up to ethernet connected NAS drive.

I created a backup of a partition, (383 GB)  ... was amazed that it took more than 10 Hrs. and the backup file was actually 6GB larger at 389 GB .... thought the backup would at least be compressed.

Then on next back up - tried incremental backup ... expected that it would be much faster, as it only had to copy across the difference .... it took more than 10 Hrs and back up file again 5 GB larger than original.

Unless I am missing something, I would be better to simply drag the contents of partition to my external drive

# It would be mush faster

# Resulting file size would be no larger

# Due to file sizes saving multiple backups is impossible

It seems using Backupper has gained me nothing, am I doing something wrong ?

All settings are default.

It is set to 'normal' compression - (yet actually makes files larger)
