Disk space issue which then just went away

Evening all

I had an issue with a Company I look after who have Exchange server 2010 installed on a VM.

They have a Typical Exchange 2010 install, with two virtual drives....(**Disclaimer alert** - I have inherited this setup!)

C: System and Trans logs
E: MDB

The disk space on the C: drive dropped to less than 2GB causing Back pressure to kick in and mail flow to stop.  This happened on a Monday, although the Friday before it had 19GB of 60GB of free space.

We freed up some space etc and it started working again, and then it ate up the 7GB we cleared off and went offline again.

I got the server going again but only by turning off the back pressure feature, then about an hour later the disk space freed itself up and it was back to 19GB free!.....

Now I figured someone deleted a stack of mails or moved a number of mailboxes and this sent the Trans logs into overdrive and ate the space....but no ones owned up to anything and there is nothing on the server to say otherwise.

The backup had a few issues so it may not of truncated the logs as expected, but I thought that would have been more gradual?...

The EDB barely budged in size during all of this....

Any other thoughts as to why the space would go and then come back?...

Thanks

Nothing in the event logs to explain why the disk suddenly emptied.

The disk space issue carried on till the Wednesday, and two backups had occurred since then.  Thats not to say that there wasn't an underlying issue of the logs not truncating.

Circular logging is enabled on the largest database, but not on the others.....
