One minute flow records are deleted from the file system FIFO (oldest first) once the appliance has filled the space that is allocated.

There is a fixed amount of space on the filesystem for completed reports.

A report template can be marked "keep until I delete it" so that any reports that are scheduled with this template are not automatically deleted from the filesystem.

When the flows or rollup records have been deleted from the filesystem, any saved report that was generated from those flow sources is no longer available.

Users have the ability to allocate additional space to the 1 min flow logs in order to increase retention. This is done at the expense of other rollup resolutions.
