I'm still not understanding what this means. Your current data would be on your "Server" (or whatever you call it). Backups are redundant, separate, copies of the current data.
To me, backup for most small businesses means the following three conditions are met:
1) Live data on a Server, with the Server locked up somewhere. The Server has redundant drives, typically RAID1 or RAID5.
2) Ongoing backup onto a removable hard drive or tape drive.
3) Rotating offsite storage of some of the removable drives or tapes.
This gives you "instant" access to items that are accidentally erased, or lost because of Server RAID array failure. In the case of a major disaster, you have multiple copies of the data offsite, including older versions.
In the case of data that is no longer stored on the Server ("archived data"), keep two separate copies in different places. And I wouldn't trust both of my copies on CD or DVD media, because of my concerns about CD/DVD reliability.
