I'll try to keep this as concise as possible to the backstory and what is currently happening.
We had a physical server running Server 2008 R2 Standard x64 that had Veeam Endpoint Backup 1.5 installed on it and it had made multiple large backup jobs that were safely stored on an internal network NAS. When Veeam Agent for Windows was released, this upgraded Veeam Endpoint Backup from 1.5 to 2.1 and changed the schema on how things are backed up. When this happened, I started a new backup path with the software, thinking the old backups would still be accessible in case a call for a restoration was made. I have found out now that this is not the case.
Steps Taken to Try to Recover
After finding out that Veeam Agent for Windows 2.1 cannot open the VBM/VBK file(s) made under Veeam Endpoint Backup, I went to Google to find a solution. One way I found that might work was to install Veeam Backup and Replication and use the Extract Utility to try and open the Full Backup VBK file. While I was able to see the backups and attempt to open, I would eventually get a critical error stating "Unable to allocate memory for storage metadata bank." and the job would fail out.
As the previous attempt would not work, I contacted Veeam Support and the tech confirmed that A) The upgrade had brought me to a new version of Veeam that does not support the backups made under the older version, B) I can attempt to install the old 1.5 Endpoint Backup and try to open those old backups, and finally C) If that doesn't work, I have no recourse other than to look to help in the forums as 1.5 is an unsupported product.
I installed Veeam Endpoint Backup 1.5 to a Server 2012 R2 virtual server, went through the File Level Restore and looked to the folder where the backups are and I am seeing nothing listed. When I tried the Extractor Utility, I would see the files at least.
The Ending Dilemma
I do not know what I can do from here as Support can no longer help me and the 1.5 Endpoint Backup doesn't see the backup files. Can anyone help me out in this situation?
