- Tape Migration
- Tape migration refers to the process of moving (migrating) tape from the data center tape library site where they are stored to the site where they will be used to get the new data center online.

| Imagine ... |
You’re moving the data center to another location. The last thing on you mind is a disaster created by shipping the backup data to the new location. What will happen if that shipment is lost?
The first impulse is to say just backup the data again and ship it again. All that is lost is time.
That will work fine for DASD backup, but what about tape data? Unless you have made a backup of all your tape, that tape data is lost forever. The obvious solution is to make a copy of your entire tape library before shipment, so that tape data can be recopied if a shipment disaster occurs.
How practical is it to copy 10s of thousands of tapes unless you know which tapes contain data critical to your data center operations?
Enter DR/VFI to identify those tapes that must be copied to avoid the tape migration, lost shipment scenario. Experience has shown that only 5-20% of the tapes in a tape library contain critical data. By using DR/VFI to identify critical tape data, now the copy problem has a reasonable solution.

What is the solution to the tape migration disaster problem? |
- In a data center holding many thousands of tapes, anywhere from 80% to 95% of that tape will be miscellaneous local backups, job logs and otherwise irrelevant to the recovery process. And of those remaining tapes, only a minority will belong to critical applications.
- A full copy of all tape could literally take months.
- Being prepared for the sudden need for a fresh set of data tape copies in the event of a tape migration disaster is the issue.
- DR/VFI is the solution.
- DR/VFI identifies which tapes are necessary for recovery of critical applications.
- DR/VFI not only identifies critical tape, but also generates the control sequences to perform the copies.
- DRVFI will turn a tape migration disaster into a contained and manageable problem in an efficient and cost effective manner -- turning a tape migration disaster into a tape migration success.
