Backups [Noob Question]

[anthony001]

ive read in the other threads that we should be doing backup when flashing kernels.
how important is it to backup for just flashing a kernel? is it even worth it? Im gonna be flashing Siyah Kernel

I heard nandroid only backups phone settings? did i understand it correctly?

Is it better to root first before doing backup? or should I unroot my phone first?

Please tell me if I got it right
Titanium = app backup?
cwm = nandroid backup?

a bit offtopic but does anyone experience battery drainage when connected to wi-fi even when not doing anything like surfing etc.?

Your choice but a reasonably recent backup should be ok .

I heard nandroid only backups phone settings? did i understand it correctly?

NO it backs up all bar EFS and Modem .

Not relevant as you cannot backup without root.



Please tell me if I got it right
Titanium = app backup?
YES
cwm = nandroid backup?

And more

Nandroid backup makes images of yours phone partitions and saves them into separated files. Truly, I never needed to restore any backup, You doing this only for a precaution measures.

Titanium Backup stores only your .apk, their data and settings. Nandroid saves all and put it into safe place (including whole system).

It's good to have both of backups, but TB can also extract .apk from nandroid backup. In this case nandroid backup is much better.

OT: WiFi always draining your battery because of notification wakelocks and working antenna. Set your phone into energy saving mode, it should help.

really nandroid backups even apk? so lets say i have dino wars installed and fpse so will it also backup those? what about the saves will it also backup the saves? also when using fpse we have a file used to play games which i think is forbidden to write its name will it be backed up too?

Everything in internal partitions system layout and .android secure partition on sdcard... just all you have got actually on your phones internal (system memory). Full backup including kernel, modem, system, apps and their data (saves, settings, etc.)

Of course if game save are stored in internal or external sd-card than its will NOT been stored into nandroid backup, but it remain on those sdcard(s) even after nandroid restore. Only formatting sdcard will remove those saves, data, etc. (also full factory reset with service code formats all phones partition including internal sccard).

If you know what a windows image backup then this works the same restores all .
But EFS and Modem .

Nandroid backup full working phone 10-am
Flash JB xxxx rom and it fails or dont like it .
Restore to 10-am full working phone Nandroid backup .
Modem and EFS stay on the phone the same .

Useful very i have done five Nandroid restores already to day after test modifications .
I also have copy of TB and Nandroid backups on PC just in case .

Important thing is to restore backup on the same recovery (cwm) on which backup was make. If partition layout has changed after nandbacup you also cant restore it, phone will stuck on bootlogo.
