How does Canary store historical database files?

Historical Database File (HDB)

Canary writes a separate Historical Database File (HDB) for each Dataset.  The files are saved by default in C:\Historian Data and separated by Dataset. These HDB files can Roll-Over, Roll-Up, and be Deleted.

• Roll-Over: This is how often users would like HDB files created.
• Roll-Up: This is how often users would like HDB files combined/grouped together.
• Delete: This is where users can set the amount of time elapsed before the HDB file is deleted.
