Hi,
Windows 2008 R2, D: volume is 319GB total space and 228 GB free space. This volume is used for data. E: Volume is 499GB total space and 445GB free space. This volume is used to shadow copies from volume D, in order to have some versions of data.
It's suspicious the low space used for shadow copies on volume E. I'me checked volume changes during some days (shadow copies runs every day at 7:00 and 12:00) and I've noticed than sometimes there is more free space after a shadow copy completes. For example:
Shadow Copy day 1 12:00 - 51.698GB used shadow copy storage space
Shadow Copy day 2 7:00 - 51.908GB used shadow copy storage space
Shadow Copy day 2 12:00 - 52.193GB used shadow copy storage space
Shadow Copy day 3 7:00 - 51.328GB used shadow copy storage space
Why is occuring this? The volume where allocate shadow copies has enough free space for save copies there, and not delete old shadow copies. It's suposing to fill the volume before delete old shadow copies.
I've cheked configuration, and is set to use the maximum space on volume E. I've traced the VSS, and all results are 0x00000000, that is succeed. I can enter to the shadow copies and seems to be correct.
I've noticed too that VSS service and Microsoft Software Shadow copy provider services stops automatically with no defined time sequence. It appears as event ID 7036 on system event viewer (service has entered the stopped state) and with event id 8224 on application event viewer (VSS service is shutting down due to idle timeout). I don't know how to solve this, what I've done is set to automatically start these services, but I think is not the answer because I'm still with this stops.
Any help will be welcome!!
Regards,
Quique
