Each backup set creates these files so we get maybe 6 sets of these every day, hence the space usage. I will look to exclude this directory ready for tonight's backup and see what happens. If these are tidied up, then I will look at removing files from this directory. Thanks for the advice, Dave Backup Exec 2010 Disc Space Usage with VSphere 4.1 Hi. I have inherited a Windows 2008 Backup Exec 2010 installation from my predecessor. This is used to backup VM's on our Estate, I have noticed when looking at the Shortage of Disc Space on the C Drive on one of the Backup Servers that the space is used in the following directory "C:\Windows\Temp\vmware-SYSTEM\". Whilst looking within this directory there are a number of the following files, each as a set of 3 that corresepond with Backup times. vixmntapi53{4bfd419c-1e64-11e0-ba9b-001185d55529}.TMContainer00000000000000000002.regtrans-ms 512KB vixmntapi53{4bfd419c-1e64-11e0-ba9b-001185d55529}.TMContainer00000000000000000001.regtrans-ms512KB vixmntapi53{4bfd419c-1e64-11e0-ba9b-001185d55529}.TM.blf 64KB I assume that this is the VCB element of the Backup Exec backup, but I am not sure whether these files are truely "Temp" or whether these need to remain for the restore process to be successful. Any help with this problem would be appreciated. Dave Solved
