Error - Create SDR - DRMTable

Hello friends,

I come for your help. I'm doing some tests on Veritas 20.1. Create a full backup of the C: drive and the system status, all good. I will create a recovery disk after a disaster, everything goes well to the point of creating the ISO, I get the following error: Error opening "C: \ Users \ cesar \ AppData \ Local \ Temp \ SDRStaging \ CustomSDRD1 \ AMD64 \ System32 \ BkupExec \ drmtable "System error message: Security pack specific error.

I appreciated your help. :)
