Symptoms
When opening the CloudBacko Go user interface, the following error message is displayed:
[PBEInputStream.init] Failed to obtain IV from input stream
Cause
This issue can occur if the CloudBacko Go user settings file (e.g. ~\.obm\config\settings.sys) saved on the client computer is corrupted.
Resolution
To login to the CloudBacko Go, please remove, then re-create the user settings file on the affected computer.
Important: Before proceeding to the next step, ensure that you have the encryption key for all backup sets of the affected user. Re-creating the user profile will require you to enter the encryption key for all existing backup sets.
For more details and best practice for managing encryption key, refer to the following KB article: Best practices for managing encryption key on CloudBacko Go
Refer to the following steps to resolve the issue:
1. Stop the CloudBacko Go services
2. Locate the settings.sys file in the .obm folder at %UserProfile%\.obm\config\settings.sys
3. Rename the settings.sys file to BACKUP_settings.sys
4. Login to the CloudBacko Gouser interface
At this point, CloudBacko will prompt for encryption key of all existing backup sets. You must enter the correct encryption key of each backup set to regain access to them.
