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)."

Hey, what does those recoveries backup?
I mean - System data/User data..
I just made a ZIP backup with CWM (6.0.2.3) and it's only 312MB (~430MB Unzipped),
and when I used TWRP I remember it was ~920MB (.win files).
In the TWRP backup there are cache, data, recovery, efs, system and boot files,
and in the CWM there are only system and boot.
I only need system backup because I backup the apps I need with TiBa.
(Is there anything else that I should backup?)

the Clockwork backup is a complete image of the phone. the recovery partition, boot partition, apps, and data. you could load a ROM onto your phone and have it not work to your liking and turn around and use the Clockwork recovery to reload the saved image and be exactly back where you were before the ROM got loaded.
on the other hand, about the best app to backup other apps and data is Titanium Backup. they don't get much better than that app for backing up your phone and having as many ways to accomplish that task as you could ask for.
Weird..
TWRP made a complete backup and it's 900MB,
and in the CWM backup ZIP there is only system.tar and boot.img.
TiBa backups only apps (and their data), doesn't it?
I need a backup of my ROM..
TWRP's backup is the ROM and the apps, and CWM's backup is the ROM only?

No CWM backs up everything it always has done.

The new partitions are not very clear to me...
What do I have to backup to fully restore the phone?
Boot, data, system and vendor? No IMGs?
Thanks!
I believe the ones that are already selected when you go to make a backup. Data, system, boot. Though I tried to make a backup last night and it failed to mount and wouldn't create a backup. It might be because I'm still encrypted
Please somebody could explain exactly what i need to backup in twrp? The system image and vendor image are needed? What they are in def? Thanks in advance...
From this forum, "the /vendor partition would only need backing up if you manually made changes to it yourself (for instance, if you use Layers). Otherwise, you can just use the vendor.img from the factory image if you need to restore /vendor."
From this forum, "According to TWRP in regards to System Image... this is a system read-only option that's intended to help you make a pure backup of your system image that you can later flash to receive over-the-air updates after having rooted or ROMed your device."
"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 isn’t available for backup on certain devices). If your device has the option, backing up android_secure and/or sd-ext may be a good idea. There’s usually no reason to back up cache or recovery (recovery not available for backup on some devices)." Answer found here.

Also make sure you backup your efs and keep atleast 2 copies eg 1 on phone and another on computer or in the cloud etc.
You only need to restore this if you loose your imei number due to corruption etc.
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.
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.
