I usually backup Data, System, Boot, and Recovery (which may or may not mean anything, it just isn't large enough so I just added it to the list).

Is there a way to wipe clean the system storage and just keep the stock ROM?

I initially rooted and flashed twrp recovery on my nexus 7 and then I decided to go to clockworkmod recovery since I'm very familiar with clockworkmod and I use ROM manager app. I'm not sure but I think twrp recovery images are still taking up space in my storage because I have one nandroid backup and I only have 19GB of 27.58GB storage. I have 1.6GB in apps, 0.8GB in titanium backup and 0.7GB misc. Downloads. Thanks in advance.

If you have remaining TWRP backups they will be in the TWRP folder on your SD... If you are certain you won't be using TWRP in the future just delete the folder. A better idea would probably be to move it to your PC just in case you might want them again...

Quick Backup Question

Just a quick question regarding a backup I created. I decided to back up on twrp only the system and boot partitions. I know that doesn't include my user apps and information but that is enough to allow me in the case of an emergency to restore a clean version of android correct?

well, i think it might suffice but it is always good to have a toolbox and a factory rom with up to date set of gapps in case something goes wrong and need to go back to factory settings. if you dont have a pc at hand i would highly suggest to do a FULL nandroid backup, i know the storage maybe limited, but you'd rather be safe than sorry

Yes.
Just make sure to factory reset** and wipe cache before booting it.
** in principle you could "dirty restore" the backup without wiping the contents of /data (especially /data/media, of course) but this would only be advisable if it was an essentially identical ROM as what was previously installed. For instance if you: did the backup, made a mod in /system or the kernel image, and then your tablet wouldn't boot.

[Q] Need Clarifications

Hi Guys!
Unlocked, flashed TWRP and rooted phone via twrp su for the first time in my life. Next move is installing custom PA rom. After browsing xda and other sites for many days to learn how to do it, basically, its just doing it in trwp recovery mode the factory reset, clearing cache and clearing delvic cache, then install rom and gapps then clear again then you are done. Is this right?
now, about factory reset, clearing cache and delvic cache in twrp, when you do this, does it in anyway delete or removes any data or setting in my phone just like when doing it in factory reset in the "Backup & Reset" in "settings" or just like what happens when you unlock/lock your phone? Or it does not really "erase anything"? Coz I do not know if I should backup first and if I must back up, I do not know which to backup or if I should have to make a full backup? Because I might not have to do backups after all for flashing PA custom rom and save time and internal space. If clearing caches and factory reset in TWRP doesnt really delete or mess up anything in android mode then I will go ahead now and install the custom PA ROM. so I need your advice before I proceed.
About flashing back stock recovery, I DL the stock 4.2.2 rom from google dev. do I just flash recovery using this file or is there another specific stock recover file to DL and flash into the phone just like what I did when I flashed TWRP which I was able to DL from goo.im?
Hope you could help me with these clarifications. I did try to search and learn from different threads about this but I not 100% sure I understood it correctly. So I made this thread to make sure of facts and clarify these things.
Hope you could enlighten me. Thanks!
Isn`t this clear enough!
Quoted from PA OP:
INSTRUCTIONS,
1. UPDATE RECOVERY
2. FACTORY RESET
3. INSTALL ROM, GAPPS, FIX-IF ANY
4. WIPE CACHE & DALVIK CACHE
5. REBOOT
PA 3+ UPDATES DO NOT NEED A FACTORY RESET,
BUT YOU NEED TO INSTALL GAPPS ASWELL.

I think you misundestood me. I am aware already of how to do it but I was just hoping on some clarifications as I have mentioned in my concerns.

I hope you would be considerate enough that I have no experience yet on this and I did some browsing and learning thru the guides and threads here in xda and other forums which is why I know the proceedure. I was only clarifying some things this matter that I have quoted now.
also, if someone would be kind enough to lead me to a link where I could find a stock recovery img. the only latest I have found is not JDQ39.
Thanks
Perform a backup of your current ROM first as this will be replaced by paranoid and all app data will be lost when factory resetting.
I don't know where all the need to wipe caches comes from.
Wiping cache and dalvik cache will not erase any of your data
Factory reset will erase all user data (apps, app data, signed in accounts, phone contacts (Google contacts will be downloaded again when you sign into your Google account during setup of new ROM) and SMS messages etc.
Here is the process I usually follow.
Place new ROM & gapps on phone storage
Reboot into twrp
Perform a backup of my working ROM
Factory reset from main page in twrp (the one that says it won't touch your sdcard)
Flash ROM &gapps
Reboot
Once fully setup. Move my old backup from phone storage to pc

Thank you very much for the reply! So in making a backup, i could use the backup feature of twrp and this is enough and would make a FULL backup? Meaning all data, app, settings, vault app and files inside vault and go back into its original state as if nothing happened? Or i am wrong? Should i be making or using another backup method aside from the backup feature of the twrp?

The twrp backup is in essence creating a custom ROM of your phone. Exactly the way it currently is. Including all apps & their data.
If you flash a different ROM and decide you don't like it.
Restore the twrp backup and you will be right back as you was before flashing the custom rom.
If you factory reset (erasing all your data) then restore the backup. It will restore all your data etc...
It's just like a save game. If you mess up. Just reload from there
Note it's not the ultimate tool. If you mess with partitions that are not included in the backup then you might have problems. But for the average user just flashing custom roms . it will backup everything you need

Thanks again for the reply. Now another clarification. So when you say the twrp back is just like making a rom of its current status or like a saved game and if i did not want the new rom then i could revert back to this backed up rom. So does it mean that if i install PA rom then restore the backup from twrp, will it overwrite the PA rom and go back to my original rom that i have backed up or will it only restore the apps and settings, etc.?
Also about this twrp backup, will it also backup and return to old state when restored certain apps like notepad and the notes i have saved in this app. The same goes to the vault app and all the files i have hidden in this app, will it back it up as well and will be restored?
Thanks for your patience..

Correct. It will revert the entire ROM back to what it was.
Basically how your device is when you backup. Is how it will be when you restore.
All app preferences and settings. All apps. Widgets everything.
The only thing it doesn't alter is what's on your internal storage
And a point to note.
If you make changes to contacts or have received texts after the backup. It will revert them if you restore back to what they were when you backed up.
It is just like turning back the clock on your phone. Putting everything back to the point you backed up except files you have put on to the internal storage

I think you are saying that you will want to restore data on PA. You can backup/restore data with titanium backup or carbon.

Whoops yes didn't read fully. You get no choice with a twrp backup. It's just the full lot that gets restored. If you want specific apps to be restored onto a new ROM you need to make backups of them using something like titanium backup on your current ROM. Then restore them on your new ROM.
You can use app like SMS backup and restore for taking your SMS history into a new rom

Thanks guys for the replies. Yes, what i exactly wanted was to install PA but be able to restore all data, apps nd settings back to what it was except that now it would be running under PA rom. If this is the case then titanium back up is what i am looking for? With titanium, is there a specific setting or option that i shld select or just press backup button? Sorry, its my first time to use titanium. Also, does the backup of the titanium also covers my notes on my "note everything" app as well as the files that i hid in my "vault" backup? Or should i make a separate backup using the apps on backup feature? And in the case of the "vault" app, should i unhide them first, backup with titanium then after restore just hide them again?
Im really appreciating the help..

I'm not really sure how either of those apps work, but I'm guessing your notes will be fine. You might have to do some experimenting with the vault app. You should do a TWRP backup in addition to Titanium. In Titanium Backup, you just press the batch button in top right corner and "backup all user apps/data" or whatever it says.
As far as system settings go, they should be restored if you choose that option after logging into your Google account (only during initial setup).

Side note: In order for batch processing to work within Titanium, you must purchase the Pro key. Otherwise, you will have to backup and restore each app individually.

It still does batch, but it's a pain...

Twrp Backup system vs system image

I just went to backup my stock ROM and noticed that twrp now lists system and system image. What is the difference between the two / do both need to be backed up and restored. Also what is contained in the vendor partitions.
Thanks

Is there any option to remove SYStem Image partition and save 6GB?

Hey there,
Is there any option to remove SYStem Image partition and save 6GB?
You're referring to what you see on TWRP?
That's not a real (or separate) partition. It's something TWRP makes. Load Disk Info or Partition Backup from play store and it is not listed. This topic is discussed in one of the threads. You can't restore it, so don't bother making it in TWRP. If I remember correctly it can be used to make an EDL package or something similar. But it's not an additional partition to your standard System partition. It's made from that.

No bro if open twrp and check backup option you can see a separate partition for SYSTEM IMAGE (6GB)
Read and research. I'm telling you look at disk part. It lists the partitions and it isn't there. It's something TWRP makes. Just don't check it when you do a backup. You can't do anything with it.

Quoting twrp.me (official twrp site) :
On most devices shipping with Android 6.0 or higher, the device maker has enabled dm-verity as a security measure. The device will signature check blocks of data on the system partition during boot at the block level. The usage of dm-verity prevents TWRP from being able to successfully restore a normal system backup. On most of these devices, you will see an option on the backup page for System Image. 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).
It is the same partition as system, just done differently. You flash it with fastboot.
