How can I find out the actual size of a backup after compression and deduplication ?
Hi everyone, I am using Veritas NetBackup version 11 to backup Oracle databases and all virtual machines in a quite big system. The using experience is nice and smooth, but my boss want me to show him the exact actual size of a backup after being backed up successfully. This means the actual size of a backup after being deduplicated. How can I find this statistics ? The Activity monitor in NetBackup Web UI shows the logical size and the deduplication ratio of each job ID, but it is suffering to manually sum them up =))) So, I really want to know that: Are there any faster ways to get the actual size of a backup after being deduplicated ? And if the only way to do that is manually calculating, what is the correct formula when I know the logical size and the deduplication ratio ?
What you can store and transmit with deduplication seems to very sensitive to deduplication rates.
The charts in the PDF are theortetical it would be interesting to see if others are getting results like these? From what I can see the ability to deupe data can have a significant impact on storage and transmission.
