I've used Todo Backup Free[^] before to back up a drive and restore it. It should have settings for specifying the amount of compression used or turning it off. It also allows you to mount and access the files of a backup image - so if you need to restore a missing or corrupted file you could do that.
I've also used Aomei Backupper[^]. Basically the same as Todo backup with a lot of the same features.
Reason for using them? They are free (for home use) and they did the job 
Otherwise you might just want to use some file syncing software[^] to sync the important files to the external hdd.

This probably doesn't apply here, but all I use at home is robocopy.exe (which is already in your %windir%\system32 directory) and a batch file.
I use nothing but VMs. Backing up is a matter of syncing .VHD files. I don't bother backing up the VM host, as there's nothing running on it except maybe for custom motherboard drivers, which take about 3 minutes to install after reinstalling the OS from an ISO, which itself takes under 20 minutes.
As an added bonus, diskmgmt.msc can mount those .VHD files, so you can access the content as if it was another drive.

Hi All,
I didn't turn my PC on yesterday, I checked mail on my phone nothing urgent. Turned it on today over 100 e-mails, what? I am amazed at the sales starting on Xmas day online and today. Does anybody really need a new dining set on Christmas day???? 
|

|
|
|
There exists at least one person who needs a new dining set on Christmas day.
|
|
|
|
|
Ah! but are they sober enough to order it, also my thinking was if you need it why wait until Christmas day, surely you can wait the few hours until boxing day...
|

Because of the fight the night before the table got destroyed.

I would agree with you but then we both would be wrong.

I needed several HashSets on Christmas day. I just constructed them myself.

It depends on how much got destroyed during the meal

To find the longest common substring between two strings.
Assume that both strings are in the same language, and that it is a real existing language with a logographic real alphabet having spaces between the words. (And no, I don't intend to get into a discussion about that, I'm certainly not an expert in languages and I just looked it up, if you have a problem with that definition assume English instead  )
You can also assume a fixed number of bytes per character and consistent white spacing, that means that EOL is always the same character or set of characters and that the space between words are always the same character.

Nah, I'm playing with Conway's Game of Life this Christmas. Thanks.

Ummm... what? 
Apparently there is an Easter Egg for it, but I don't see how that qualifies as "ironic".

Hint: Start by writing a tokenizer.
Advanced: Write / use a multi-lingual tokenizer like the ones used in enterprise search solutions.
Extra points: Make a performance comparison running the tokenizer in expansion and reduction mode.

What's the tokenizer for?
|
|
|

Hmm, how do I phrase this?
A tokenizer creates tokens.

Of course it does, but what is its purpose in the problem?
|
|
|
|

Procrastination!
You move the problem of finding the largest common substring in two strings to finding the largest common sequence of tokens in two token streams.
You know that it ruins a joke if you have to explain it, don't you?

Right, the tokens are just characters, so that's done.

Might be sacrificing space for speed?
What size character and integer? Did it convert individual 8-bit characters to 32-bit integers? Or put four characters in each integer?

Yes but not badly so.
PIEBALDconsult wrote: What size character and integer?
UTF16 (windows internal) and Int32.
The point is simply that integer math is faster than string comparisons.
