If you did not use the Intelligent Disaster Recovery Configuration Wizard to set an alternate data path for the *.dr files, you can set it manually.
See Manually editing the default data paths for the *.dr files.
Copies of the *.dr files, which contain the computer-specific information for the computer being protected, are necessary to automate the recovery of an IDR-protected computer.
Backup Exec automatically creates the *.dr file during a backup and stores it in the Disaster Recovery Data Path default location on the media server’s hard drive, which is
C:\Program Files\Symantec\Backup Exec\IDR\Data\<computer name>.dr.
Symantec recommends that you do not change the default.
You can also specify an alternate location where a second copy of the *.dr file is stored so that the *.dr file is available even if the media server has been damaged. It is recommended that the alternate location be on another computer or on a different physical drive than the default location, and that it be a mapped network drive.
