DataTypes

DataTypes are the core of what XSnapCourier needs to do its job. Basically, a datatype is another name for a combination of Snap and retention schedules. In each Datatype, we will have the following Defined:

• Snap Time Value
• Snap Time Frame
• Retention Time Value
• Retention Time Frame

The “Time Value” fields are an integer, while the “Time Frames” are strings denoted as “hour, day, week, month” etc. They would combine to read something like this: Snap Time Value: 1, Snap Time Frame: Day Retention Time Value, 10, Snap Time Frame: Day Put together, this would interpret as “Snap the volume once a day, and retain those snaps for 10 days.” This way we can assign a DataType specifically to a Volume on the XIO and have a uniform schedule that we can change at any time.
