Image backup smaller and drive unrecognizable at boot.
Dear all,
I got, Acronis True Image 2019, Build 14690.
I've noticed the .tib complete image backup (is smaller than the original source files). They are compressed?
Also the drive is not recognized as boot media, in windows boot manager. What am i doing wrong?

ATI 2019 #14690 is back level, you should update to the final build #17750.
All backups are compressed by default by an average of around 20%.
What drive are you trying to boot from via Windows boot manager? An Acronis backup is not a bootable image - it is a backup archive file. If you want to try to boot from a backup image then you would need to convert it into a format that allows this, i.e. to .VHD
Dear Steve,
It's an external D: drive i am trying to boot from, via Windows boot manager.
I want it to be booted by the laptop itself; not a virtual machine, so i am checking if .VHD will be recognizable by the Windows boot manager.
If not i need to find a software that does an exact copy of my laptop C: drive, like Samsung's Data Migration.
But a software that does this with an external drive!

Microsoft do not normally allow Windows to be booted from an external USB drive unless you have paid for an Enterprise license and used Windows 2 Go to create the drive!
However, there are other utilities that can allow you to do this, some commercial / paid and others that are open source / free -ware.
One I have used recently to do what you ask is Rufus which can create an external bootable Windows 10 drive.
See webpage: How to Run Windows 10 From a USB Drive - for the steps needed.
Note: this would be a new install of Windows 10 on the USB drive but you can sign in with your Microsoft Account and activate it when connected to the normal PC.

Dear Steve,
I have a licensed Enterprise Windows.
What i want to achieve is an exact copy of my laptop ssd to external ssd.
This way i will be able to boot the external ssd and have the exact same environment as my laptop internal ssd
Acronis does not have software doing this?

If you have the Enterprise version of Windows 10, then you need to use the Windows 2 Go feature to create a bootable external SSD. Acronis cannot do this for you.

If I recall correctly Windows on the Go is no longer supported by Enterprise versions, not sure if introduced in 20H2 or earlier.

Creating a bootable partition on the external ssd is not the issue. I know how to do that.
What i want is all my programs there (and working), as well.
As Acronis does not offer this (unfortunately), i have to find an application that does :)

I have done this a couple of times, once with Hasleo WinToUsb which copied my working Win10 installation to an external drive but which took some time to do so and performed very slowly due to my choice of USB device at that time.
The second time I used Rufus (as per the link in my earlier update) and did a new install of Win10 to a spare NVMe M.2 SSD in an external USB 3.x enclosure, and which works very well but would need me to install more of my programs etc!
Both of the above were done as exercises to see how the tools worked. Hasleo WinToUsb is a paid tool that I got a copy for free from the Giveaway of the Day website when they offered it during a 24 hour period. Rufus is freely available.
Acronis can restore a backup image to an external drive but does not do the 'magic' needed to make this bootable when used externally - the drive would need to be installed internally.

Thanks Steve. Much appreciated!
I'll be able to find a solution eventually.

EaseUS Todo Backup claims to do this. I haven't tried it but I have been curious.
