I am running 4.5fp6 on an Unix (11i) Master/Media Servers. I have been backing up the information store/public folders with nightly full backups. The admin stated that he saw the last full was from Dec. 30th. Even though I have been performing fulls nightly. They have been finishing with an exit status of (1). The error causing the exit status of 1 is due to a second information store that the admin is testing with. The backup is unable to back up the second information store. My question is will the exchange client NOT remove transaction logs if the backup exits with anything other than 0 ?? Just wondering if any of you have run into this situation. I will more than likely just split the two information stores up to prevent this in the future but would still like to know the cause. Thanks!
