Hi,
I have the following configuration and I wanted to confirm if after 3 months it will erase the first month partition? In other words, I am supposed to always have 3 month of data right?
Thanks!
You'll always have at least three months of data. The partition changeover may depend on the time and date the partition was set. Tag History Providers | Ignition User Manual says,
| Property | Description |
|---|---|
| Enable Data Pruning | Partitions with data older than a specific age are deleted. The check box is not selected/enabled by default. Note: Data pruning works by deleting old partitions. Therefore, data will only be removed when a partition has no data younger than the prune age. |
| Prune Age and Units | The maximum age of data. As mentioned, the data is deleted by the partition, and could therefore surpass this threshold by quite a bit before all of the data in the partition is old enough to be dropped. |
(Emphasis mine.)

Thanks for the confirmation, I appreciated!
For some reason we lost all data of the last year. We were supposed to have November, December & the current January but it is not. Maybe something happened and I'm not aware.
thanks again
