Hello, This is Ryotaro.
I want to ask about Databackup for DT6.5.
My customers want to keep all the data of DT6.5 for a certain period of time.
I want to know about the diffrence of session data with PWH DB data.
I think session data = PWH DB data, so I don't have to back up the DB data if when I get the session data.
my understand is correct or not?
Basically there is a huge difference between 'Session' and PWH data. The session data is your PurePaths data (to keep for the short period of time) and the PWH is your metrics data (to keep for a long period of time).
A session is a set of diagnosis data related to a specific System Profile.
Examples of a session are:
Depending on the location where a session is stored, there are three types of sessions.
The Performance Warehouse database stores time series from both system monitoring such as CPU and memory usage, and PurePath timings. Data is stored at one-minute intervals at the highest resolution. Granularity is diminished at the medium (hour) and low (day) resolutions.
