Hello,
Moving from OBIEE 12.2.1.4 to OAS7.0 used to setup cron to run the bar file backups and it is easier to automate. Now as DV snapshot is the far most recommendation from oracle for a good recovery in OAS instance/catalogs, automation option is a must. No one wanted to login to console everyday and click to run the snapshots, please work on this or fix the exportarchive.sh to be a best option for recovery scenario , Thanks!
