I have an Exchange 2003 server and I noticed that the folder that contains the EDB and logs was over 226GB. I checked it out and discovered log files that dated back several years.
I am in the process of moving to an online backup solution so I decided to try to backup Exchange prior to setting up the new backup system. The old backup has been failing for a while now and we need to get something stable.
Once I started the backup (to disk with NTBACKUP) it hung up and eventually failed. I cancelled what was left but the server was busy at 100% so I let it sit for a while. When I came back, I noticed the server was running faster, but I also noticed all but today's logs were gone. Can someone please explain to me if I lost anything? Is it possible for the store to contain the messages in the logs even though the logs still existed or did the log files contain messages that were not "commited" for years? I have trouble believing the latter. From what I've read, the log files sit there until they are commited. Do they get commited with a full backup or just purged? I checked my folders in Outlook and I still have mail dating back to when I started almost a year ago.
Thank you in advance!
