Do I need to backup data in order to be able to revert back to my stock Rom? My understanding is that if I did a backup of the System, Boot, EFS, and Cache then I should be fine. Only gripe is that my Apps and app data will be lost. Is that correct?
You are right

i'm using a htc desire running on cm6.
when there are newer versions of cm and i would like to update to it.
what is the best way of achieving this without having to wipe the data/settings/etc?
if there is no such way, what can i do to backup settings/data/apps so that once i update to a newer cm , i can just restore my stuff?
what about Rom Manager Premium, theres an option to check for rom updates, would Rom Manager update your rom for you?(and keep all settings/data/etc?)
Yup.
it does everyting. buy it. seriously.
vision
seriously?
i use titanium backup and it works fine for me..
another option to back up your apps & system data is the nandroid backup on the recovery menu..
titanium backup requires busybox and for that to work i need to be nand unlocked.(which im not).
i always thought that nandroid backup will backup everythign to a state, so if i were to upgrade roms, and then use restore, wont it just revert me back to the previous state(not updated)?

You are correct. A nandroid restore will undo your update.
If you're upgrading to a newer release of CM6, you should be able to do it without wiping your data. Wipe dalvik and cache, flash the rom, and reboot. You'll have new featuers but all your old apps and data in tact.
Nandroid backup first for good measure though
oh okay, so wiping dalvik and cache would just wipe all settings(including home screen layout, widget placements, folders etc?)
some tutorials that i've read about updating roms, is that i dont even need to wipe dalvik and cache, anythign bad about that?

Nope, dalvik and cache wouldn't even affect your settings.
The cache is the temporary cache used by the Android operating system, and the Dalvik-cache is the cache used by the Dalvik Virtual Machine. The only thing about wiping them is that the first boot will take longer as they rebuild their indexes and such.
Nine times out of ten, you'll be fine without wiping these. It's just generally considered "better" if you do.
Again, nandroid backup and try it out. If it doesn't work without wiping, restore back and wipe the caches.

For some reason we can't back up all the partitions in nandroid. It should be enough to backup system and data. Optional: boot, logo (if you modified M boot logo), cache (usually not necessary), sd data (if you use ext partition on SD card).
With nandroid of system and data (and the others, but only if you use them) you should expect to be able to go back to exactly how your phone was at the time you made the backup. But you will lose changes you made after you made the backups.
When I'm about to start testing ROMs, I backup system and data. To go back to my pre-testing ROM I restore system and data and then wipe cache partition.

You want to say system and boot ?
Because changing a room modify system.img and boot.img
The boot.img is the same on all the ROMs thanks to the locked bootloader.
Yeah, I never even bother changing boot.img from the sbf version. If I did I'd probably use the Russian one because I think it was the most recently compiled.
Ok, I wasn't knowing that I always flash boot.img that come with ROM.
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
Hello guys. Is it necessary to change data file system back to f2fs before restoring?
Restoring what, a backup of stock rom by what i assume? If you went of custom, and now you're coming back to stock yes, you gotta restore data partition to f2fs before restore a backup. If not, it won't work.
