When a backup set is duplicated is the archive bit set?
No
All a DUPLICATE job does is copy the backed up data to another tape or B2D folder, in a format that allows restore from the second device. It does not affect the original data at all
maybe script something to delete files that have been backed up as part of a post command
if you create an "archive" job, then the original data is deleted after a successful backup, but again, DUPLCATE does not affect the original data in any way
At this Point I'd like to either delete the B2D files or erase them off of the temporary B2D location.
Why? Is the data sensitive enough to warrant this? If you manage your OPP (Overwriter Protection period) properly, backup Exec will reuse the BKF files in the B2D target when the next job(s) runs
