Mod edit Al1000: Split from: https://www.bleepingcomputer.com/forums/t/647980/cloning-software/

I also use Macrium, and is it OK to ask a similar question here? Otherwise, move me to a new thread.
 
I usually make an image, but this time I'm deciding.  I've looked at the tutorial posted above.  Am I correct that a clone also copies the free space from the original drive?  And the diagram seems to indicate that I can choose not to copy the useless recovery partition that came with the machine. Is that correct?

I use Macrium Reflect pretty frequently. If the recovery partition is AFTER the first two Windows created partitions, I've found it's generally safe to de-select it. Also, you would have to do this if you are cloning to a smaller drive since it can't shrink middle partitions.

If you make an image of the drive, the image will only be the size of the used space by default (unless you turn up the compression). If you go to write that image to a new drive it will remember the size the partitions were.

In either scenario Reflect will shrink the last partition to make it fit on the smaller drive, which is why you want your main partition to be the last one.

Nope, just checked. Turns out the Recovery Partition is first, but it's tiny.  When you say it will shrink the last partition, do you mean it will remove empty space or compress the partition?

 

My external HD is only 80GB. This might be too tight to clone anyway:

That first partition isn't a recovery partition. That's a small partition that Windows creates on installation that stores some boot info and things. It's only 100MB total, so fairly inconsequential.

It won't fit on an 80gb drive. That last partition there doesn't have enough free space to shrink onto an 80GB drive.

You could use a tool like Minitool Partition Wizard to shrink the middle partition down, and then move the last partition back next to the middle one so all the unused space is at the end. As it is now, you'd need a 181.79GB drive to fit it, because it can only shrink that last partition down to 20.65GB.

You don't mean 181.79GB. Typo? I'm using only about 70.

Sadly not a typo. You might only be using 70, but because that 161.14GB partition is trapped in the middle, Reflect can't do anything about it. It can only shrink partitions starting from the right, so all it can shrink is the last partition. That unused space in the middle partition might as well be used since it has that last partition sitting at the end of it.

I thought the HD was 100GB, just found out otherwise!! Going to shrink C in Easeus Partition Master, which I already have, then I'll move D.  You saved me from a mess.

 

Would 52 GB be a reasonable size for C, or more? I've already removed all the garbage with CCleaner, and  I can always move some data to a CD if I run out of space on D, but I can't fool with C. After 21 years of computing, I  have only 20 GB of Data.

An 80GB hard drive only has about 74GB of usable space. Shrinking the C: partition to 52GB would make the clone about 72GB with very little extra space on the D: partition. I'm fairly certain it would work, but it's really close.

I think I'll buy a larger external HD. Thanks

OK, I'm cloning now to a new HDD. I've been backing up for years, but one thing puzzles me. How can Macrium clone a C drive when Windows is open and using files? Partitioning programs run in a sort of DOS, but backing up happens while  everything's running, in fact right now.

It works by using Windows Volume Shadow Copy service. It's the thing that allows Windows to make System Restore points. Basically, when the backup starts, it uses VSS to take a snapshot of your system, then it uses that to make the clone/backup. The way it really works is far more technical than I could explain, but it makes for some interesting reading if you want to look it up. I'm still not entirely convinced it doesn't use some sort of voodoo.

Duh. I'm not convinced it makes a perfect copy, but I've never had to restore more than 1 file to test it. 

 

Macrium wouldn't backup, separately,  just 2 folders, my Firefox and Thunderbird profiles,  every night, would it?  Will Windows Backup do it? Otherwise what would you recommend? it has to be automatic.

Honestly, I think you're good with just Reflect. I've had no trouble using it for my regular backups, and I've cloned dozens of drives at work and had no problems.
