8. Build a Successful Archive Run
Project Plan
Archive jobs can run for a long time!
Per 600 MB file, VBAK = 12 hours write, 16 hours delete, typical 4 files/quarter
Items to consider
Need 2 plans: Test and Production
Resources: 2 wks/qrtr testing, 2 wks/qrtr executing
Preplanned system down times
Month end processing – system performance
Other projects
Contingency
