Cool [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

You probably want an adb backup or a nandroid backup.

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

The backup can be restored from your recovery (nandroid backup) or using adb (for adb backups.) You can't directly boot from it, not really.
For the boot sector, I'm not sure what that is for Windows. The bootloader, maybe? Android has that too, of course.

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
