My normal strategy is to move the log files to a different disk after verifying the DB is in a Clean Shutdown state. We then take a flat file backup of the logs and a new, full online backup of the database is taken.

Smith Sent: 12 August 2010 20:35 To: MS-Exchange Admin Issues Subject: RE: Log Drive Full You can do that IF AND ONLY IF you know exactly which log files are required to remount the Exchange database. It's a whole lot easier to tell someone how to compress files than it is to tell them how to determine which log files they need to remount the Exchange database. Besides which, at the time you remove the log files, you also lose point-in-time recovery of your Exchange database. That is, it is potentially a lossy recovery and may impact a company's RPO (Recovery Point Objective). I rarely, if ever, recommend a lossy recovery when there are other options still available.

IIRC Symantec's BackUp Exec will do that if you have the Exchange agent installed plus a couple of config changes to backup exec. I am talking about Ex2007, though. I'm not sure about other versions. > From: mich...@smithcons.com<mailto:mich...@smithcons.com> > To: > exchangelist@lyris.sunbelt-software.com<mailto:exchangelist@lyris.sunbelt-software.com> > Subject: RE: Log Drive Full > Date: Thu, 12 Aug 2010 19:25:54 +0000 > > Such as, don't select the EDB file or *.jrs files or E00tmp.log etc. etc. > > The valid log file format is EnnXXXXXXXX.log > > Where nn is 00 - 99. > > And XXXXXXXX is a hexadecimal number. > > So, E0000000964.log is a "normal log file", but "E00.log" and "E00tmp.log" > and "E00res00001.jrs" are not. > > Make sense? > > Regards, > > Michael B.
