[Q] Initial backup/ image for new device

Hi,

Very noob with a very noob questions

I read a lot about backups etc... Some have to be rooted first...

I'm used with my Windows computers to make a genuine unstarted system image (Ghost, now Acronis)
When I have a new computer, I take out the main HDD and make an image or boot with an Acronis boot disk and make an genuine image, can I do something similar with Android devices?

Is EFS the system image or just the system files, restoring an EFS backup is enough to make a device bootable again without Root?

Windows PC suitable for this? ADB I guess...

Perhaps it's not possible because I haven't see any topic about making an genuine image before first start of an new device or restoring a factory image... Every time Root is involved


Thank you to make me a little wiser Sorry for my poor english

Hi GermainZ,

Thanks for the tip, I'll look for both alternatives, probably ADB I guess...
Will the backup be bootable or the simple fact to recopy all the files is sufficient to boot the device? Windows uses a boot sector, is there something equivalent in Android?

Thanks

of course the bootloader I lost my brain I think

Is the bootloader a part of the firmware or is it copiable as a file, I'll find it out
On a Windows HDD it's a track (boot sector) but UEfI bios modifies the game now

So a full Android system restore is firmware + backup I guess
