Regarding Recoverpoint snapshot granularity
Hi all,
I have several questions regarding recoverpoint snapshot granularity. Can somebody help?
1. Assume i set the snapshot granulatiry fixed/second, will it take a snapshot every second even if no change is made on the production volumes ?
2. I can only see 1000+ snapshots in the recoverpoint navisphere GUI, how can i see all the snapshots ?
Thanks.

Hi there,
If there's a need for an urgent answer, then a SR is in order (can be opened even for a question).
To answer your questions though:
1) Yes, even if there's no change on the production, there might be OS writes, especially if replicating datastores.
2) That is by design, you can search for a specific timeframe when testing a copy through Unisphere for RP/CLI or our RESTful interface.

First i would thank you for your answer.
Just curious, your said 'Yes, even if there's no change on the production, there might be OS writes, especially if replicating datastores.',
Assume i just replicate the data luns(not virtual machine), when i close the application(means no write to the data luns), will it create a snapshot every second ?

Even in CLI, i can only see 2 snapshot in the last 5 minutes.

Current Image: 07:21:31:246971 27/09/2016
BTW, What does current image mean ? The image just distributing to the replicate LUN ?

Hi there,
Try to use image access to search in a certain period to get the full list of images.
When performing image access and you see current image, it means that image access is enabled on a specific image, that's the current image.
