Point

Creating a snapshot is optional. However, create a snapshot to revert the system back to the previous environment in case the software update is canceled or the software update fails.

6.5.1.1 Stopping Operation

Follow the procedure described below to stop operation.

Make sure that the shared folder is not being accessed. If it is being accessed, wait until the access is completed or stop the operation that is accessing it.
In the Used cache capacity panel of CSG Web GUI, check that Untransferred data is indicating "No". If it is indicating "Yes", wait until it changes to "No". You can estimate the completion time of the data transfer as follows:
1. Calculate the average cloud transfer performance (MB/s) from the performance data in the Cloud transfer performance panel of CSG Web GUI.
2. Check the Untransferred value (GB) in the Used cache capacity panel of CSG Web GUI.
3. Estimate the transfer completion time using the following formula with the values obtained above in a and b.
```
Estimated transfer completion time (s) = (amount of untransferred data + 1) * 1024 / average cloud transfer performance
```
Log out from CSG Web GUI, and close the web browser.
