I'm running Exchange 2010 on two nodes using DAGs.
Normally I use Windows Server backup to backup Exchange and truncate transaction log files about once a week.
Recently I let it slide to about 4 weeks and tried to do a backup today.
When trying to do the backup I get the error message:
"The application will not be available for recovery for the component Micorsoft Exchange Server/Microsoft Information Store/Exchange 2010/74cf3917-4bd9-89ed-ec
. Contact the application vendor for help"
I looked this up on Google and found that it might be because I have too many transaction log files. So I checked, and sure enough in the MB database. I have many files, dating back to the last successful backup I did. I have copies of these transaction files.
My question is this, can I delete the transaction log files from last month without harming the Information Store. Seems to me the only thing that would happen if I deleted these log files from last month would be that I couldn't use them to restore if I needed to :) Is that so? Do I need to dismount the database to delete those files or can I just use Explorer to trash them?
See attached image for the files I am talking about deleted. There are a few hundred of them all similar to the ones in the screen shot.
