What size must the SavVol be to accommodate the changes?
You would like to run Celerra Replicator on one of your production file systems. You found from watching the last incremental backup that you have a change rate of 2% a day on that file system. The file system size is 100 GB. You want to calculate the size of the SavVol to be able to continue with replication even if you have a 4 day network outage between the source and destination site.
