When creating backups with 'esadm backup -d...'; Later can I view these descriptions from the files?

We create regular (daily) backups for Ops Center using the esadm command.

when creating backups with:  "/opt/SUNWxvmoc/bin/ecadm backup -v -d 30Apr15_Thursday_Backup"

Can I later view these descriptions by listing/the backup files? 

I don't even see this information entered in the Logs created during each backup.

Where exactly is this stored, and how can I see this string to search through them???

     thanks;
