We are looking at going from a Tape only shop to a Disk2Disk plus Tape shop as we must have an offsite copy for DR.
We would like to:
- Run SYN Fulls weekly
- Run Incremtals daily
- Copy all Jobs to Tape (shipped offsite daily)
My question is do Synchronous Copies copy the entire dataset for each Syn Full each week, or just the changed data??
When I copy to tape, I'd like to make sure we have a copy of the entire backup set each week in case of a disaster event that would destroy my DC. I'd like to only have to recall the most curren't week's tapes and not all the tapes from when I started doing the Aux copies to tapes?
Hope this makes sense
Is the Syncrhonous Copy the correct way to go to achieve this or do I need to also implement a Selective Copy to copy only the most recent Full data to Tape as well?
