Sony PC Companion backup extractor

Utility to extract data from sony pc companion. Tutorial on how to use the program is over here: http://www.johannesdeml.com/blog/extract-data-sony-pc-companion-backup/
Download the file: https://github.com/JohannesDeml/pc-companion-restore-data/releases

For encrypted files (Encrypted with android not the companion) you will need to change your security settings and use the command line to run the program. Requires Java 7. Handling encrypted backups requires the JCE unlimited strength jurisdiction policy.

Commandline: java -jar restoreData.jar [password]

Build project with IntelliJ

Download the latest version of Bouncy Castle Provider jar (bcprov-jdk15on-*.jar) from here:

http://www.bouncycastle.org/latest_releases.html

Drop the latest Bouncy Castle jar in lib/, import in intellij and adjust build path if necessary. For building a jar artifact make sure to remove the signing information in bouncy castle (see readme in lib folder). Syntax for running the jar:

extract data from fullbackupdata file:	java -jar restoreData.jar
extract data from encrypted fullbackupdata file: java -jar restoreData.jar <password>

If the password is not given on the command line, then the environment variable ABE_PASSWD is tried. If you don't specify a password the backup archive won't be encrypted but only compressed.

Alternatively with Ant:

Use the bundled Ant script to create an all-in-one jar and run with: (you still need to put the Bouncy Castle jar in lib/; modify the bcprov.jar property accordingly)

java -jar abe.jar pack|unpack|pack-kk [parameters as above]

(Thanks to Jan Peter Stotz for contributing the build.xml file)

Alternatively with Gradle:

Use gradle to create an all-in-one jar: ./gradlew and then:

java -jar build/libs/abe-all.jar pack|unpack|pack-kk [parameters as above]

Notes

More details about the backup format and the tool implementation in the associated blog post.

Packing tar archives

• Android is very particular about the order of files in the tar archive. The format is described here.
• Incompatible tar archives lead to errors or even system crashes.
• Apps with the allowBackup flag set to false are not backed up nor restored.
  • (you can try restoring manually via adb push and adb shell)
• Errors are only printed to logcat, look out for BackupManagerService.

The safest way to pack a tar archive is to get the list of files from the original backup.tar file:

tar tf backup.tar | grep -F "com.package.name" > package.list

And then use that list to build the tar file. In the extracted backup directory:

tar cf restore.tar -T package.list

You can now pack restore.tar and try adb restore restore.ab
