Is there any method available to remove selected data from a backup tape without erasing the tape? I have several tapes with numerous backup sets on them and need to remove selected data from each backup set while maintaining the remainder of data in each backup set.
The need arrives from data existing in the backup that was involved in a legal matter. The judge has ordered that all data concering the case be destroyed. Had we known this on the front-end, this data could have been placed on separate media.
I could take the backups, restore each set, remove the designated data, then backup the data again, but this will be an extremely time-consuming process.
