How to repair a corrupt iTunes backup or SQLite file

Every now and then, iTunes backups may turn out to be corrupt. Error messages shown in iTunes for a corrupt backup can vary depending on the main issue, sometimes without giving many clues on the real problem.

In most instances, it’s almost impossible to repair corrupt backups, and certainly not without a full understanding of what is missing and how to fix it. The next best option is the recovery of data and files that still exist, using the free edition of iPhone Backup Extractor.

The following messages may indicate that a backup is corrupt:

  • "Error loading backup in [...] Not a valid mbdb"
  • "Couldn't load backup in /Users/Username/Library/Application Support/MobileSync [...] file opened is not a database file"
  • "[...] there was something wrong with the manifest an underlying SQL exception occurred"
  • "AuthData Value was not a dictionary/node"

Don't despair though: we might still be able to help with the data recovery. Our support team may well be able to help, and they can do so if you're able to share copies of your Manifest.plist, Manifest.db, Info.plist and Status.plist files.

We publish a guide for working with corrupt backups, and it describes the main ways of recovering data in detail.
