Hi Peter, It sounds like you're dealing with a VM environment, possibly either Hyper-V or VMWare ESxi -- and that there are two types of backups being done on the Virtual Machine; host replication and guest backups. Both of these types of backups being carried out against the VM Guest from the VM Host would utilize the Volume Shadow Copy Service on the Guest OS... If this is correct and that they are using Volume Shadow Copy Service then you will need to either update to v17 or stop using the volume shadow copy service until the update to v17 is completed.

Note: If the replication backups are being done every 15 minutes via VSS then I don’t see how turning off the 4D Server would be an efficient way of avoiding issues. More information about 4D's support of Volume Shadow Copy can be obtained from the following blog post: https://blog.4d.com/enterprise-virtual-machine-snapshot-support/ ^ Feel free to share that blog post with your customer or their technical team / contractor. -Tim -----Original Message----- From: 4D_Tech <4d_tech-boun...@lists.4d.com> On Behalf Of Chuck Miller via 4D_Tech Sent: Wednesday, December 04, 2019 7:55 AM To: 4D iNug Technical <4d_tech@lists.4d.com> Cc: Chuck Miller <cjmil...@informed-solutions.com> Subject: Re: O/S Replication and Backup interaction with 4D (2004, v15) In all cases they should be able to set backup to exclude particular files and or directories.
