Backup Server system disk failed, now i cant access the backups

hiho!

A day ago the system disk of our Acronis True Image Echo  Workstation Backup Server failed, so we had to repace the disk. The backups were located on an external usb harddisk. After setting up the new system i installed True Image and the Backup Server again.

The problem now is that the backup server didnt recognice our backups on the external usb drive. I already point the standard backup location back to the folder where it was before the crash.

How do i get True Image Echo Workstation Backup Server to recognice the backups again?

Thanks,
