How long roughly should it take to copy 238GB of data (HDD Backup image) from a local drive on a computer to a NAS drive?
Connected by Ethernet, The computer is showing its connected to the LAN at 100Mb/s. The NAS and computer are both connected to the same switch on the LAN (not via the router or anything). Both have fixed IP address (not DHCP). The transfer rate is currently 10MB/s, and estimated time is 7 hours!!!

10MB/s is the max you'll get on a 100Mb/s connection.
Time will increase if there are lots of small files.

Sounds about right. 10MB will be maxing out the 100Mb connection.
230,000 MB / 10 = 23,000 seconds = 6.6 hours.
Could be a bit more depending on the size of files. The more smaller files the longer it will take

Fair enough. Would a gigabit switch help then im guessing? Both the NAS drive and computer have gigabit LAN ports.
There is only actually 2 files. A HDD image, and a HDD image database file (only a couple of meg, the majority of it is the 1 large file).

Why not just direct attach the NAS and PC if you don't have a switch. Most NIC's are autosensing now so crossover shouldn't be needed.

The computer runs headless so i use RDP to connect to it. Its also my media server so need it connected to the LAN really.

Not got a second NIC or something? Just thinking of an immediate solution for you rather than having to faff getting a gigabit switch.
Had 2 large migration projects over the weekend - using a gigabit NIC we were able to transfer approx 2.9tb in 7.5 hours on one box - 112MB/sec
Had to do the same on a second but had the ability to use LACP on the switches we had, so had 4 NIC's aggregated together and the throughput was just over 320MB/sec
