Hi All,
When creating a snapshot using Trident CSI, how is the snapshot size determined?
For example:
Scenario 1:
I have a PVC with a capacity of 1 TB, and 100 GB of data is currently written. If I take a snapshot now, what would be the size of that snapshot?
Scenario 2:
In the same PVC, the data increases from 100 GB to 150 GB. If I take a second snapshot at this point, what would be the size of this new snapshot?
Thank you,
Kannan V

I know you think this is a simple question, but it isn't. I can tell you with certainty that at the time the snapshot is taken it takes 0 bytes. Then as data changes on the filesystem, particularly data modification or deletion, the size of the snapshot grows. How much it grows depends on the rate of change. Because of the dependency there is no way to tell you how quickly snapshots will grow in your environment.
