Hi I'm trying to understand log files and Exchange 2007. I understand the basic idea, but was hoping for some help with more concepts. So if I look at a log folder, there are logs such as E01.log, E010001AED0A.log, E01res00001.jrs. There are also other logs such as E01.chk and E01restoreenv Could someone explain what the E01.log actually does? From what I've read, it's the log file that actually being written to, but that doesn't make any sense to me. The E01res00001.jrs is the reserve log to allow the store to dismount gracefully if space runs out, correct? E01.chk is the Checkpoint file which keeps a note of which logs have been commited to the DB, correct? And the E01.restoreenv file is the equivalent of the E01.chk but for restored database? Am I thinking along the right lines?
