Environment
Vmware NSX-T
Cause
The Cryptographer Changes after an upgrade or a change
Resolution
Reach out to the backup solution
way to test this issue
1- went we are trying to set it up with in NSX if we have the wrong private Key we will get a similar error
2- Use an ESXI host as the source for the backup
- create a folder for the backups on a datastore
- Cd into that folder and collect that path
Note: you can use command pwd to get the path quicker
and add the information into the backup and trigger the backup
