SAP Backup on EMC Datadomain

Hi all,

we're doing SAP backups via Brtools + EMC's DataBoost technology for serveral weeks - this scenario works pretty well for taking backups but

we're facing a problem in connection with retention period. Where do you guys configure it? Assuming the parameters resides

in the  *.sap files (default: 30 days) seemed to be wrong as we tried to recover a backup that was older than 20 days thus the question, where do we configure the retention period for backups using BRTOOLS and EMC DataBoost technology?

Thanks in advance,

Rafael
