You may need to backup your data if you are planning on changing your phone, be able to get back everything in case of a theft/loss or to just get the phone the way it was before (without losing Contacts/SMS).
I did it for the last reason & surprisingly the battery life doubled, exactly what I needed (probably because of lots of background services not running anymore).
Better backup before the world gets upside down on you.
(Note: This guide is for both non-rooted & rooted phones but users having root access should try Titanium Backup)
Things we will Backup
- Contacts
- System Settings
- SMS
- Call Logs
- - Applications
Software you’ll need
Contacts & System Settings
If you have a Gmail account associated with your phone (& definitely it is) than it’s a non-issue because all your contacts are automatically backed up with Gmail & in the same way restored automatically on a new/refreshed phone.
But if you still somehow want an offline backup or all you contacts in one file, go to Contacts, Press the Menu soft key, Select Import/Export, Select Export to SD Card, Select OK & all your contacts will be saved to the SD Card.
For system settings make sure in Privacy Settings ‘Backup my Data’ is checked (in previous versions, before Android 2.2, check ‘Backup my Settings’).
This will, like contacts, backup your settings online & restore them when needed. Some known settings that will get restored:
- WiFi Settings (including saved networks)
- Wallpaper
- Accessibility Settings
- User Dictionary
- Privacy Settings
- Certain Apps are Re-Installed
But don’t just expect you stuff to instantly re-appear after a restore. Give your phone sometime. The User Dictionary restore may only work in Android 2.2+.
Backing Up SMS
SMS Backup & Restore does what its name says and does just that. It exports all you messages to an XML file on your SD Card. You can get it Installed from the Market.
SMS Backup + is another tool that will backup all your SMS/MMS & Call Logs to your Gmail account. It actually sends them as email to your inbox & labels them appropriately. Am not exactly sure about it’s restore process though it claims it can restore them.
SMS Backup & Restore has a Preview feature to preview messages in the backup file before restoring it & also allows you to find duplicate messages, plus a delete all messages in memory option too.
Call Logs
Install “Call Logs Backup & Restore” from Android Market. The options are simple, just click Backup & it will save your logs into an XML file. The saved file has no ‘styling’ information so if you open it in IE, FireFox, Opera, and Chrome etc. it won’t look neat but is readable. The time, date & phone number can be read from it easily. Android keeps up to 500 logs, so that’s the max it an backup.
The same preview and delete options are here too.
Applications
Start Astro File Manager, press the Menu key & select Tools. Select Application Manager/Backup. Here you have an option to select individual Apps or all of them. Choose the ones that you like & click Backup, Oh you can’t click it… no worries just tap it 
[OPTIONAL] AVG Anti-Virus Free
AVG Anti-Virus Free is a ‘One App’ solution to all backup operations. The catch? You cannot backup individual category like say just the messages or just the bookmarks & the restore will delete all the previous info & replace it with the ones in the backup file. If it’s a new system that’s completely OK. Still it’s a powerful tool and largely hassle free. The ‘App Backup’ will backup your Applications, the same way as Astro. Why it is in the end and not recommended as the only solution? Because it is a Beta feature & may hang during the restore process.
Important Step:
Your call log, SMS, Contacts & Applications are now on your SD Card. Connect your phone to a PC & transfer the files/folders described below or email the smaller files to yourself (I use Gmail) as a fast easy way for online storage/retrieval.
Files: 00001.vcf (or 00002.vcf it that one already exists)
Folders: CallLogBackupRestore, SMSBackupRestore, backups (contains your apps), droidbackupdir (if you used AVG Anti-Virus Free).
Refresh Your Phone
Go to Settings > Privacy > Factory Data Reset.
You phone will restart and it will be like new 
Copy the above mentioned files back to the SD Card, install the respective apps and hit restore on each one of them, that’s all. Besides these there are tons of different apps on the Android Market, you are free to explore them Do check Lookout Mobile Security, unlike the other apps it backs them up online.
We found out yesterday that Motorola’s Xoom would be shipping sans Flash support on Verizon Wireless, and while Big Red claimed that an update would be doled out this spring, the folks at Adobe are pointing to a far more specific time frame. In a new post over at the Flash Platform Blog, Adobe has confirmed that “Flash Player 10.2 [will be] pre-installed on some tablets and as an OTA download on others within a few weeks of Android 3.0 (Honeycomb) devices becoming available, the first of which is expected to be the Motorola Xoom.” We’re guessing that the company’s going public with a statement like this to fend off fears that the Xoom may be waiting an eternity for Flash, in essence removing a bit of fear from hesitant early adopters. Either way, it’s excellent news for those eying a Honeycomb tablet of any flavor, and we’re going to take the liberty of taking “a few weeks” to mean “a fortnight.” Cool, Adobe?
