Promoting a backup to the next level

Hi Folks,

When an interval is promoted to the next highest interval, is it done with a simple rotate and rename:

mv <interval-1>.<max> <interval>.0

or is <interval-1>.<max> rsync'd and hard linked into <interval>.0, meaning that there will be paths to both <interval-1>.<max> and <interval>.0 at the conclusion of the backup?

Thanks for the help,

Chris.

It's an "mv", and only changes the inode that holds the directory information: much, much, much faster than doing rsync.
