Notice to people using Titanium Backup to restore

Please stop using Titanium Backup to restore system files when you upgrade you ROM! Some system apps and settings are incompatible when newer ROMS. When I do backups I backup my user apps to one folder and system apps in another. This way I can just restore my user apps and their data in a batch restore but with the system files I only restore data to apps with the same version.
I make this thread because n00bs keep restoring everything including their incompatible system files and start to whine about the ROM being slow, apps FCing, and other assorted mishaps. I've already helped 2 n00b friends who had phones stuck in bootloop after doing full restore.

Which program would you suggest?
This is an interesting argument

I use Titanium Backup, I just don't restore system app data to incompatible apps.

I backup using apps + system data option.
In this case, system data refers to data that are related ONLY to apps right?
When I upgrade to gingerbread, you think it will cause problem??
Or, Should I only back up apps?

When you backup user apps (the ones in white), you will backup the app + its settings and data.
When you backup system data (the ones in green), you are backing up only system settings, like SMS/MMS, Accounts, Calendar, Timezone, Phone logs, Wifi APN, etc.
When you backup system apps (the ones in red), you are backing up ONLY the settings and data for that app, not the app itself. THIS is what Intratech it asking you to NOT backup.
Why? Because the next ROM you install, will most likely have a different system app version than the one you previously had.
Usually:
Different apps == Different settings === problems

So restoring the green ones should work fine? Especially the Application Widgets is important for me as it is much work to restore.
How to restore the red ones? Market + Samsung Apps?
If I do minor updates 2.2->2.2.1 is there the same recommendation to only restore user apps/data?
Thanks.

Why would you want to backup market and samsung apps?

I restore things like my APNs, contacts and SMS from system data using Titanium backup. Across a range of ROMs I've never had any issues, although I'm not restoring every bit of system data- just a select few.

It is faster to restore app's data than waiting for market to come up with updates and configure all manually.
Does system backup do a backup of new versions of system apps?

the market automatically downloads apps when you open it. personally, i do not back up my apps but instead use my internet connection to access the market and sownload all the apps back at one go. Q: Is the same service(auto download downloaded apps) on samsung apps?

I do backup system data however I'm careful when restoring stuff. I check app version number and if they are different then I don't restore any app data for that.
The market doesn't automatically restore your user apps, that's why I restore those.

The market does auto download those apps that you have downloaded before but are not on your phone.

hello,
I know it's off topic, but can i just ask you a simple question?
when restoring with TB, does screen has to be on all the time?
because for me, when screen goes off, whole process stops and when I turn it back on, it resumes..
Is there an option available in TB where you can set to have screen off while restoring?
cheers

There's a bug with SGS and WakeLocks commands that TB never sorted and never supported or even gave feedback.
ScreenOn: will hang your screen On unless you reset phone
Keep CPU: screen bug is solved, but scheduled backups won't start in standby. They'll start later when you turn screen on. When screen is off, the will keep running (preferred setting for me)
Disbled: you'll have Keep CPU bug added with the pause of jobs when screen auto Off, as you expierience
To be on topic again, restoring green data is safe. Especially SMS, MMS, calendar and contacts data

For myself i duplicate apps folder on phone in case backup fails .
Root Explorer and copy APP file to sd card and or PC .
Backup fails then it just requires each app installing from the sd card .

I don't think something so painfully obvious needed a thread.

I disagree because many guys get confused as to what system apps mean. I had this problem after I restored system apps a long time ago. Since then I don't backup my system apps at all but chose individual system apps like Maps, Gmail etc. to back up.

about titanium backup

so i want to change again my rom again but now i have a lot of things on my phone that important to me
so i would like to use titanium backup but im not quit sure how to use properly
so can somebody explain to me how do i backup everything
and when i mean everything i mean like saves from games and sms and music and pictures and more
so please i need your help
thanks

Using Titanium Backup:
1. Menu -> Batch -> Select RUN Backup all user apps + System data
2. The backup will be in the folder on ur SD card. Copy and save it in case u earse the entire SD card
Using Recovery:
To backup enitre ROM which ever you are currently using. Reboot into recovery..
Currently I use Clockword Mod, so I know how to do it only by this one
1. Reboot into recovery mode.
2.Under Backup & Restore do the nandroid Backup which backsup the currently using ROM with data.
3. This will also be under the folder ClockwordMod in ur SD card backit up in case u do SD card formatting
For SMS, Call Logs & Pictures I use McAfee Wavesecure which I bought long back and backsup all the data.. not sure about Titanium backup for SMS & stuff...
I think this might help you.

Excuse a newbie question, but doesn't the nandroid recovery just take a snapshot of the current setup with ROM and all?
How do you use it with a new ROM?

You use the nandroid if the new rom doesnt work or you of some other reason want to go back to the old rom.

Don't backup System Data if you are changing from one ROM to another, you will invariably get problems backing up system files that won't work smoothly with the new ROM. Just backup user apps.

No, that's fine. You can back both up and just restore apps and app data with no problem. I've never backed up system data I really don't see the point, I guess you could backup and restore to the same ROM, but i'd rather just start afresh each time.

Being able to backup system data selectively isn't a bad idea, i.e. Wi-Fi access points and literally one or two other things, if someone is after a system backup this is where nandroid comes into play, in my opinion.

I do agree backup for user apps. Also I would prefer Nandroid to restore the old ROM fully. Since I have been using some CM7 RC builds & also nightly builds.. i started to restore system data as well, which literally helps me to have all settings as well.
Also he can run Restore apps with data alone...
But it is upto OP which method he prefers..

Open the app and select Backup/Restore and long press on the system data you want to backup. You should exercise caution and not backup system data that will potentially disrupt another ROM. Wi-Fi Access Points, User Dictionary etc can all be found in there. Hope this helps.

Or the way I did it was just go under the backup/restore tab and scroll till you find what you want to backup ie. Bookmarks, wifi, etc then you are just backing up what you want and need

I have a question regarding Titanium that I hope you can help with...
I've just upgraded to the Gingerbread RUU, so I lost root and can't get it back, or frankly want to have it back, but I've backed up a number of apps with Titanium Backup, and is there any way to reinstall them?
They're all saved to my SD card, and Titanium Backup obviously refuses to work.
I can't and don't want to get root back, so is there any way to manually use these backups, or use them with another program?

You can recover the apps by searching the TitanuimBackup folder and extracting the APKs from the Zip files. It's obviously not possible to recover the data as it's zipped up in a tarball and it requires Superuser rights to access if using Titanium, however I don't know that it's not possible to manually replace the data. If you unzip the tarball and extract the folder to your desktop. If it's the BBC News app for example the folder should look like this after you extract it.
'Data/Data/bbc.mobile.news.uk/cache
-----------------------------------/databases
-----------------------------------/files
-----------------------------------/shared_prefs'
I don't know if you can access Data/Data from the phones internal memory without root, I am using Root Explorer. Try with Astro, I am guessing you can read/write to Data/Data without having S-Off as I am not getting prompted to switch to R/W to delete files (I have Root and S-Off).
If you can read and write to Data/Data without root and S-Off you can manually copy and paste the data over after installing the app, it will take ages to do if you've got any number of apps and I am not ever sure it will work, but I suppose it's worth a go.
I hope this makes sense, it makes semi sense to me as I read it back!

[Q] Titanium Backup: restoring after wiping

I have the premium version of Titanium Backup which I have been using for over a year with much success.
I have one query which would make it really awesome if it can be accomplished.
I normally only use it when doing a ROM upgrade. When I am getting ready to upgrade, I delete all my old backups, do a new set of backups on all user apps + system data, and wipe and flash the ROM. Then, when I'm back inside, I go into the Market and download Titanium plus the Pro unlock, and restore the backup.
(First of all, is this what you guys do? restoring all system data shouldn't screw up the features of the new ROM from the old one, right?)
The question is: Is there any way to have Titanium run without having to first go into the Market, find the app plus the unlock, download it, and install it? i.e. If I could just run it straight off the SD card, or install it straight off the SD card without having to use the Market.
Ideally, it would be even better if I could have a startup script on first run where it just restores the full set of apps + system data after I've flashed the ROM.
Is this at all possible?

download or extract from a rom the titanium.apk, put it on sd-card an install the apk after flashing new rom and it´s done.

Never restore system data as it can and has causes issues. It is only advised to restore user apps and data never system data.
As for your other question no not that I know of. Most roms worth anything already include TIBU so all you have to do is install the pro key and run it.

Start Titanium backup
Goto menu/more/create update>zip
scroll down and hit "create update.zip"
when you install a new Rom just use "add another zip" when in Rom manager or 4EXT recovery
Goto SD card and select "update.zip" from root of SD card
Hope that helps

Thanks, that's great!
Do you know if it is smart enough to bundle the Pro unlock into the update.zip? I opened the zip file up and there only appears to be 1 APK in there.
Would it be difficult (or even possible?) to manually adjust the update.zip so that it includes the Pro unlock APK?

restoring
So I'm returning my nexus for a replacement today. Some kind of battery issue that makes it keep turning off every night:
http://forum.xda-developers.com/showthread.php?p=34923533#post34923533
On restoring, if I understand right, I'm going to move my titanium folder back to the new nexus to the SD card area.
Run my TiBU apk and just restore my apps and associated files.
If I understand right, I Should Not restore my system files right? (Although i did a lot of customizing i was hoping could come right over).
Then when i have it all customized again, I'll back up the new system and hopefully it won't have any issues anymore.
Just an android noob talking it through, sound good?
I'll be installing the rom and CM10 again of course before doing this.

How to copy the system 1:1 to a new device by using TWRP

I got a new device by RMA and now I want to copy my nandroid backup made with TWRP to the new one.
Which partitions do I have to copy?

Most of the partitions are system based, so don't touch them. All you would want to copy is data, but I am not even sure that would work, without a boot loop? I keep all my data backed up with Titanium. And Google drive would restore most of what you had on your phone as long as you were allowing setting>system>backup.

Data, as it is the one where your settings and app updates are stored. Just be sure the new device is running the same version of Android as the old.

Restoring a nandroid backup of the data partition to another, identical, device will work without causing a bootloop given the precautions I describe above. Do note however that Google's backup only restores items acquired through the Play Store. Alternative app stores such as Amazon will not be restored, apps acquired through Amazon will not be restored, and any apps sideloaded will not be restored. Since Google's restore function doesn't restore everything, any backup solution - like a nandroid backup - is going to be a better alternative.

Thanks for the clarification that you can restore data as long as you are on the same version, does it have to be at the same security update level as well?
That is why I use Titanium for apps I got off of Fdroid and other sources. I will make sure I try the Nandroid data backup next time.

Security level shouldn't make a difference, but that is not something I have attempted. The pair of identical tablets I have here are running the same security update.

Thanks, data did the trick.

I am having the same problem with the fingerprint reader after restoring data from one phone to another, what files did you delete in TWRP file manager?

Solution for fingerprinter:
1. Boot into TWRP
2. Go to advanced>filemanager to acces the files in your phone.
3. Enter the folder /data/system/user/0
4. Delete following files: ./fpdata/user.db, settings_fingerprint.xml
5. Reboot to system and set up new fingerprints with the fingerprint wizard
6. Everything should work normal
Was not easy to find, but it's easy to do

OnePlus Switch vs Google backup+restore

I have googled this but not getting a clear answer so hoping someone here can confirm.
I am switching from a OnePlus7T to a Nord and I was just wondering what the best option is for transferring my apps and content etc from 7T to Nord.
Last time I went from OP6 to OP7T I did the google restore on the 7T and then also ran the Switch app.
But I ended with lots of duplicate stuff like contacts and other stuff (can't remember what else was duplicated)
So, should I just install Switch onto the Nord - but don't Google Restore and then just run Switch? Will that do everything?
Or is there a better approach?
With my previous non OnePlus phones I would just use Google and some other SMS + Call History restore app and then do other stuff manually.
Thanks.

Hi harryw66, i think the switch app is the better solution as Google Backup doesn't backup everything.

Thanks - I received the phone earlier today and went the Google router - seems to have backed up most stuff - but not my folders etc - so guess I will have to do them manually - just need to be sure the other stuff does not get duplicated...

I use..
- SMS Backup & Restore by Sync Tech to backup messages and call logs and it never failed since first use many years ago. Also it has Google Drive backup, auto delete old messages in drive,.. etc.
- SMS organizer by Microsoft as SMS app. It is the best SMS app I used and still using, though it failed a couple of times in backing up the SMSs.
- Titanium Backup to backup all my apps with data daily.
- SyncMe Wireless by bvaisoft for backing up my entire phone contents to my PC after midnight, daily, including Titanium Backup data.
- To clear the storage space taken by Titanium Backup, the Tasker will delete all these contents at early morning.
I've been using these settings for years, though restoring about half number of apps' data didn't work well with Titanium Backup with 7T. So I used OnePlus switch to copy these apps, but without their data.

Thanks - yes I ended up using SMS Backup & Restore by Sync Tech to backup from old phone and restore onto the Nord.
I used to use SMS Backup+ from Jan Berkel with great sucess in the past - but this seems to be broken now due to Google auth changes...
Cheers.

OnePlus Switch doesn't backup everything. It didnt back up files in Downloads or documents, unless it was an image, or video.
App Data is random. Works for some apps but not for all.
