Hoping someone might have come accross this problem before and have an idea of a fix.
We recently upgraded our vCenter Server to version 4.1, since this upgrade the transaction logs have started going wild in size - I have researched this quite alot, and have the following observations / comment and fixes applied.
1) The database is in Simple recovery mode.
2) It's running MSSQL Express (5)
3) The database was an upgrade of version 4 to 4.1
4) The Veeam backups running overnight cause this transaction log to exceed 4GB
I'm pretty sure this isn't a fault of Veeam, and it's down to vCenter Server upgrade, but the reason for posting here is that it's definately the backups causing this to happen, I have run the backups during the day and watched the log file go nuts, I have run a trace on the database to ensure I am watching the correct traffic etc and it's definately coming from the software.
This wasn't happening before the upgrade so obviously a compatability issue between the two of them - has anyone seen this before or experienced this issue, the only fix I currently have is giving the transaction log file a drive of it's own and leaving it to run wild this obviously isn't a long term solution.
I have noticed that a backup of a windows server which has a LUN which is short on room is causing this to rise the fastest (like 1GB+ when sitting at 99% complete), however this might be a red herring

Any help is greatfully appreciated, I have a technical call with VMWare but not heard anything yet, and wanted to see if anyone else has witnessed something similar.
TIA
