Instructions on how to troubleshoot and resolve issues with corrupt backups
(!) Please note that if you lost the password to the archive, we won't be able to restore it. Recovering a lost password or restoring an archive without knowing its password is not possible
If you have a corrupt backup and need to restore data from it, the general strategy would be to:
- Copy the corrupt backup archive to the internal hard disk drive (if the backup is on an external resource/media);
- Mount or explore the backup archive and try to restore files or folders from it.
To troubleshoot the issue please see the Troubleshooting section of this article.
If an Acronis product creates corrupt backup archives, please use the following scheme to troubleshoot the issue (click to enlarge):
The troubleshooting scheme will guide you through steps to find out whether the backups are detected as corrupt due to the machine's faulty hardware, or they get corrupted during data transfer from network or USB, or due to the faulty transfer cable, or if the issue appears while the software is running in Windows or other loaded operating system, or if the issue is with Acronis Bootable Media.
(!) If a backup task with automatic post-backup validation fails with an error message about backup corruption, while manually started validation succeeds, then such case should be thoroughly investigated - please contact Acronis Support.
(!) Acronis does not guarantee that images created with a newer build of the product will be supported by older builds. This means that restoring an image created with Acronis True Image Build 8163 may fail with Acronis True Image Build 8076.
Contact Acronis Support if you have questions or need assistance.
