How to Configure the Historian to Delete HDB2 Files After a Period of Time
Open the Canary Admin. Select the 'Historian' tile.
Select 'Configuration'. Select a DataSet that houses the old HDB2 files that must be deleted.
Under the
section, set the 'Delete:' field to 'Custom'. Adjusting this interval deletes all files older than the specified time period. The deletion does not occur until the next Roll-Over.
Do not make this setting less than the Roll-Up time, doing so will delete the entire Roll-up file that the latest HDB2 file gets stored in. Users may not want to delete all that data.
