Hi all.
I just made my first TWRP backup there and just accepted the defaults as I always have on any device.
After having a bootloop issue due to vendor.
I'm wondering when making a backup should I tick the Vendor / Vendor image ones too or just leave the defaults?
Vendor, not the img, I believe.

I'm getting ready to make a backup in twrp, but have a question. What is vendor and vendor image. Should I include both in my backup or not?

+1. Also system vs system image.
Only thing you need to backup is what is selected by default. System, data and boot I believe ?
Hey guys, quick question. When I go to do a backup in TWRP, I have the option to select System or System Image. What's the difference/benefits of both?
Thanks!
I found a good answer on the TWRP website:
What should I back up in TWRP?
The default backup options in TWRP are system, data, and boot. For most cases, this is sufficient for backing up a ROM. (Note that in some rare cases, boot i...

"A system image backup takes up more space than a regular system backup, but the system image backup is a bit-perfect backup that, when restored, will not break dm-verity (assuming that you don’t break dm-verity before making the backup)."
Cant recall so many partition options in my earlier phones, but with Oreo 8.1 on Rn5 I find these:
boot, cache, data, recovery, system, system image, vendor, vendor image, modem, efs
In all, 10 backup and restore options. I understand data and system are the main ones for backup and restore. And for safe keeping modem, efs as separate backup to the side (not used in regular backup/restore operations).
What about all these new partitions I'm seeing? system image, vendor, vendor image? If I am backing up 9.5.19 and moving to (miui 10) 8.8.23, is data and system all that is required to backup? Will 8.8.23 (fw-less rom) affect these new partitions mentioned? So to restore 9.5.19, just restore data and system and that is enough?
Much thanks.
I want to have a full Backup of ROM, in TWRP when I go to backup these options is checked by default:
Boot
Data
my question is , what is about this other option that backup have and didnt checked ,for what are they :
Bootloader (lk)
Bootloader(lk2)
Cache
Cust
Cust Image
Dtbo
for what is this options and what will happen if I will checked them all?
what is the best to check and do backup?
System, data, boot, dtbo, and cache will be enough. But really you should probs ask in your twrp thread as the other options are very device specific and has nothing to do with building your own. Unless you are trying to better understand it so you can build your own
Backing up the partitions, System, System Image, Vendor, Vendor Image, Data, and Cache altogether brick the system. Is there any idea why this bricks my device? The only partitions that do work are System Image, Vendor Image, Data, and Boot

First of all, to restore such a full backup with all possible options like System and System Image isn't necessary.
You have always to choose if you want to backup/restore 'System' OR 'System Image'. Same for Vendor and Vendor Image.
While the first one does 'only' a backup (via copy) of the data on System or Vendor (which is smaller in space but sometimes problematic), the second one named Image does a full backup of the partition via DD.
Needless to say that the second 'Image' option is the way to go, since you get a perfect 1:1 backup/restore.
