Hi Charlotte, Oracle Secure Backup is a backup suite, competing head to
head with Commvault, NetBackup, TSM, Avamar, DD Boost, Veeam, Rubrik and
Cohesity, to name a few. I have no experience with Oracle Secure Backup
and cannot even begin to guess what the problem is. However, having
worked for a backup manufacturer for a long time, I know that backup
products are very complex and have features like deduplication and
compression which can behave in rather interesting fashion, to put it
mildly. I would recommend opening a ticket with Oracle about the
problems you see.
