Can a nandroid backup created on android 6.0 be restored on android 8.1

[Android Central Question]

So I created a Nandroid backup of my data more than a year ago,it was an emergency because my device was almost dead and it wont boot(except for the recovery mode).
Now i have my new android device which has android 8.1 ,so i tried to insert the SD card and boot it in recovery mode, but it wont give me any option to restore the data(or even backup).
(Backup =12 GB , Available storage =16 GB )

Any help would be appreciated.

Nandriod backup was created when rooted and custom recovery , unless you root your new phone and install a custom recovery I dont think you'll be able to.

You can open the backup on a PC, find all the files and copy them to the new device, but unless it's in something like TWRP format, there's no direct "restore from nandroid backup" app. You could learn a little Linux (Android runs in Linux), then mount the backup as a loop device. That would give you access to the individual files in the backup.

mount -o loop disk1.iso /mnt/disk

will do it on a Linux device (disk1.iso is your backup - use whatever name it has, /mnt/disk is where you want to see the files in it)

or just open the backup in a program that handles iso files, like 7zip. (You'll have to drill down through a few folders to get to the files.)
