Summary0000963: Windows Backup using VSS
DescriptionWe have a Baros-Server running on FreeBSD. We are trying to make a backup of a Windows Server on which an Exchange Server is installed.

Everything is running OK. But after some time we noticed that the Exchange Server transactions logs are not being rolled and that the backup size increases substantially.

After digging around on the Windows Server we saw that the volume shadow copies are not being deleted (yes, we are using Enable VSS = yes ). We think that this may result in the growth of the transaction logs.

Here is an example (on the Windows Server via CMD):

diskshadow
add volume f:
begin backup
create
end backup

The "end backup" will delete the shadow copy. And we assume that this will also lead to a truncation of the transaction log.

So, the question is: Does Bareos (the Windows Client) ends the WindowsVSS in a correct way, so that the shadow copy is being deleted?

If you need more infos, we can gladly help.

Sorry, but Bareos is not able to backup an Exchange database using VSS at this time.
As it doesn't handle Exchange correctly the Logs are not truncated and you'll expierience a growth in transaction logs.

Is there any progress towards backing up Exchange 2016/2019 and have it commit the logs? Windows Server Backup has two options for the VSS, Full and Copy. The Full method will truncate the logs. Is there any way to pass the Full method for VSS with Bareos?
