I'm picking up from trying to research this and it's probably somewhat similar to Q_20496976.
I am responsible for a few Exchange servers. I don't have a lot of experience behind me, but I'm working on the education. Two of these Exchange servers (one of them I set up, an Ex2003) that is, two of them do not have this problem where the MDBDATA builds up, however there is one, an Exchange 2000 that has this issue. It was set up a couple years ago, so I haven't been looking for the problem, until it became a big problem... MDBDATA is 55 GBs! The server stopped. I cleared some space and got it started again, but this needs to be solved.
- I know how to set up exceptions for the Antivirus, so it's not that it's scanning the Exchange folders. I actually set that up.
- it's not relaying, because I've tested it... unless there's some authorized account being used for relaying. I don't think it's likely.
We don't make a daily backup of this server. It doesn't actually have the performance for that. We just have everything archive (from the Outlook clients) to an archive folder on a server that is powerful enough to back it up. (Weird, but it works for us. There are so many ways to backup Exchange. The other ones are done differently. But whatever.) Anyway, I'm wondering about the comments made by other people in this other question i mentioned above, in this case.
Here's where I need more education, I guess...
If there is no daily backup, does this cause the MDBDATA to grow? (There is a daily backup on the other Ex2k server, and MDBDATA does not grow, however, the Ex2k3 server also does not have a daily backup, and it's MDBDATA does not grow. So, I don't see the correlation.) So, I'm trying to nail down why this Ex2k server's MDBDATA is growing so fast.
So, the other options that they mentioned were:
- zero out database pages/ enabling circular logging - I don't understand this well, but we're not doing backups the traditional way anyway. Can anyone comment on that? Is this just because e-mail tracking is on?
Anyway, in the end, I need a way to control these growing files and I would appreciate help in understanding this. I'm certainly not going to head in there and start deleting things. What I really need to understand is if I turn off this mail tracking or solve some other issue, can I delete the text-based files in the MDBDATA, or can the system do that for me?
I need some answer soon as we're approaching 1 GB left, so I'd sure appreciate it. Thanks for helping a guy out whose trying to be successful at this.
Let me know if you need more info.
