So I've read that regular LineageOS updates work with "dirty flashes" but the bigger updates (between majoe Android versions) require "clean flash".
Is it possible to somehow save all the system and application settings and data between the big upgrades requiring clean flash?
Thanks and sincerely

Boot into TWRP, select the Backup option, then select "advanced", select the data partition but do not select any other partition, swipe the slider to start the backup. When the backup finished, move the backup file to external sdcard or PC if you don't have external sdcard.
When you flash your ROM(do not store your ROM and gapps in your internal storage, store it on external, if you, don't have external, store it in your internal but don't wipe your internal when you do your wipes), wipe system, data, cache and dalvik cache then flash your ROM. After the ROM finishes, while still in TWRP, you can either go ahead and restore the data backup that you created or you can reboot into system to let the ROM do its initial load then immediately power off, reboot into TWRP, select Restore, then restore the backup of your data partition and reboot the device. I would let the ROM boot then go back to TWRP and then restore the data.
Thank you sir!
Is there any downside of restoring from backup instead if setting up everything manually?
Are there any downsides of choosing one if the two options proposed by you over the other?
Sincerely

1) no downside, it restores all settings, apps and app data to exactly what you had before flashing the update.
2) no downsides, it is just that letting the ROM boot first then going back and restoring the backup reduces chances of things being buggy after the update.
I recommend that you boot into TWRP, select Backup and make a full backup of everything except for internal storage. Then, when you flash your ROM then let it boot then go back to TWRP, select Restore, then select "advanced restore" then select only the data partition and none of the others(this will restore only the data partition from the backup and not the others), then swipe the slider to start the restore process then reboot the device.
The reason I say to create a full backup of everything is so that you have a working backup to restore if something goes wrong with the update process. It gives you a restore point to go back to so you can troubleshoot what went wrong then try again. And if everything goes right with the update, you won't need to restore the whole backup, you can just do the advanced restore and restore only the data partition and then you should be where you want to be.
I don't know if this will backup and restore your SMS/MMS text messages, you may need to backup/restore those via one of the SMS backup and restore apps in the PlayStore, there are several that can do this.
Thank you again.
Does this backup work for migration between any custom ROMs let's say from LineageOS to PixelExperience or only between versions of the same ROM like from Lineage 18 to 19?
Is it possible to migrate the same set of settings and data from stock ROM with locked bootloader to a custom ROM?
Sincerely

Do you have to backup to stock rom or can you just install a rom on top on another without backing or w/e?

You should backup your rom before flashing, this way if anything goes wrong you can go back.
You should always wipe, wipe, wipe.
Wipe data/factory reset
Wipe cache partition
Go to Advanced and wipe Dalvik Cache
After the wipe go back and Install zip from sdcard. After install I do another wipe on the Dalvik Cache then fix permissions. Remember Wipe, Wipe, Wipe.
so as long as I do that then I can install a rom over another and delete the previous one while doing so?

I recommend making several backups.
First, make sure you have Clockworkmod installed via nvflash. Then make a backup. Download the backup to your pc for safe keeping (just in case things go wrong).
Use Titanium Backup (free version works, but buy the full one if you like it). Use the batch feature to back up all user apps. Do not back up system apps.
When installing a new rom, especially roms that use different versions of android, you should wipe everything you can except the external sd card (where you keep your backups). Wiping "system" is important.

Since I just got stuck with a broken nightly on cyanogenmod I wanted to ask for a solid way to backup the system, apps and all settings of my device (which is a HTC one S ville).
I thought about backing up my cyanogenmod system with TWRP?
Is TWRP able to backup all the apps and app settings? Does it also include for exmple Tasker profiles?
What is a backup app like titanium for? Do I even need it if I back up frequently with TWRP?
Thanks in advance
The twrp backup is an exact image of all your partitions: cache, boot, system and data including the file system. It'll contain everything you have on your phone except sdcard. It's downside is that you cannot restore only a specific app or it's data, you have to restore all of them.
Titanium Backup on the other side, backups the apps and data and allows separate restore for each app.
If you do frequent twrp backups and you would restore everything at once, you don't need TB

Agree TWRP
What do you guys typically do when you try out new ROMs and want to do a clean flash and get back up and running quickly?
1. Restore via Google
(Very slow to redownload everything, doesnt restore everything)
2. Sony Backup/Restore
(Sometimes Restore doesnt work)
3. Titanium Backup
(This is what I currently do, but can also be extremely slow)
4. Titanum Backup (creating update.zip for use in TWRP)
(Backup only seems to allow backup to internal storage so I run out of space)
5. Something Else
I use twrp recovery menu to backup my data, system and kernel
I usually backup to my internal storage since its faster than my mSD
From there i wipe and flash
Or to restore wipe and restore (since cache/art cache wasnt included in the backup)

If you wipe/restore from TWRP, then haven't you've just wiped your brand new ROM and returned back where you started?
My question is specifically for people who try custom ROMs do a backup and restore.

I think i made a bit of a typo there
when going to flash
- backup
- wipe
- flash rom
- flash gapps if needed
when going to restore
- wipe (cache, art cache)
- restore
I'm sorry, I still don't understand.
1. You backup (system, data, etc)
2. wipe
3. Flash rom (which writes new rom to system and data)
4. Then you restore your backup, which now overwrites system and data, thus erasing the new rom you just flashed
I need a way to restore apps and app data while keeping the new rom, otherwise it defeats the purpose
long story short: just to assure myself for everything to go smoothly while installing Lineage OS 14.2 i stupidly decided to tick the 'system' box on factory reset for TWRP along with the standard data, cache and dalvik. now i tried to system restore the backup i have on my sd card and it says error 225 at the end and its stuck on boot!
what have i done wrong? can you no longer restore if you tickbox the 'system' thing; does the backup option not backup literally everything? did my files corrupt? will the 'format data' option (deleting everything on internal storage), then trying to restore fix it? HELP.
phone is a Samsung Galaxy J3 2016 (J320fn) fwiw

If you wiped everything, you can't just restore the system only, the default restore that restored all partitions that were backed up, is what you need.
Or, you can boot into TWRP, then select the wipe option, then select advanced wipes, then select the system, data, cache and dalvik cache partitions then swipe the slider to wipe. After the wipe is finished, flash your LineageOS ROM and gapps.
After flashing the ROM and rebooting the device, if you want to try to restore the backup that you made, boot into TWRP, when retoring a backup, it isn't necessary to do any kind of wipes because it automatically formats the partitions before restoring the backed up data to each partition.

i solved. it turns out i just didnt have enough memory to extract the system restore into internal storage.
what do you mean though? the only problem im having in the stock OS now is that my phone will randomly stop charging and/or display different battery %'s (one time it said i had 89% for 15 minutes straight without charging it. i rebooted it and then it said it was at 94%), as well as im unable to manually update (says my original OS was modified in a non authorized manner)
is there anything i can do in TWRP in regards to either of these things? maybe re flash stock OS? (how would i go about doing that without losing all my data?)
So I made an oops, *sadface*. Though I'm glad I backed up the important stuff before I went from OOS to LineageOS. I decided to see how RROS was with Q, So I downloaded needed files, and I proceeded with what I thought was necessary. RROS 8.1.0, proper gapps. Had Magisk and TWRP on phone already, so I did factory reset, install RROS, TWRP -> reboot TWRP -> flash GApps, flash magisk... Clearly something went wrong as my phone went default encrypted with no way to decrypt it. Apparently I had to wipe the data and start out freshy fresh. So, what did I do wrong? How could I have avoided this? I've done some research and it seems that with the A/B partition, format data is required? If that is so, so be it. I'd just like to know if there was an alternative way to switch ROMs without having to backup all data and restore it after formatting data. Way more hassle than I anticipated.
Imo, there is no way to change custom rom without formating data, otherwise your storage will end up encrypted. I am just using automatic google backup for apps, settings, wifi, call logs and sms and google photos for images and it works great. You dont need to take care of it at all, just set it and it will automatically backup all your data periodically and when you swith to the new rom you will have choice to restore all of the above from your backup during initial setup.
