iPhone Backup Script

If you jailbreak your iPhone there are multiple ways of doing so. One method requires you to restore your phone, other issues can arise from some of the jailbreak specific applications when upgrading firmware. The best method when upgrading in this situation is to do a clean install and re-apply your jailbreak software (something like package backup can help in this situation). To re-apply the core settings such as SMS / Voicemail / AddressBook can be more hassle.

To get around this I have started to write a backup script (Mac / *nix specific). This will, via SSH, backups installed applications Documents folders, all core settings like SMS / AddressBook / Calendar etc. You will then be able to restore set up the phone as a new phone and then sync all apps and media. Once done you will be able to use the restore function of the script to apply the backed up data.

The script is work in progress and does need to be tidied up a little. The restore function is being written (testing to be done when next firmware / jailbreak is release :-) )

The script and instructions provided below:

• Run the backup script - this should be used in conjunction with iTunes. If anything fails restore from iTunes backup. To run the backup script SSH will need to be turned on, on the phone. You will need the mobile (or root if you prefer) password and the IP address of the phone.
• Run the backup script as follows:
• ./backup.sh -i 192.168.2.3 -u mobile -s
• This will setup the SSH keys and ensure everything is setup for the script to work.
• To run the backups issue the following:
• ./backup.sh -i 192.168.2.3 -u mobile backup
• After you have set up an synced the iPhone you will be able to use:
• ./backup.sh -i 192.168.2.3 -u mobile -d 20090911 restore
• There are options the script can take -a for application only backup, -c for core components and other features will be added as I require them or users request them in the comments!

The script:
