Export this page. VSS is a copy-on-write driver that intercepts disk writes before they actually happen. The contents of the disk are written to a shadow copy buffer before the write takes place.
The disk image, therefore, represents an exact point-in-time and is not affected by disk write activity during image creation. Macrium Reflect cannot cause VSS to fail.
Any failure is caused by other software or system configuration problems and will affect every program that uses VSS. Failures must be located and fixed for disk images and file backups to complete successfully.
VSS uses writer components to ensure that the file system is in a stable state when creating your disk image. For example, SQL database writers ensure that all transactions to databases are complete before allowing the shadow copy service to continue.
Thanks for the post. I will certainly comeback. Have you ever thought about creating an e-book or guest authoring on other sites? I know my visitors would value your work. If you are even remotely interested, feel free to shoot me an e-mail.
Another advantage is the safety feature. The length-to-diameter ratio, pitch, length of each zone and helix angles of a screw must all be matched to the plastic type being used.
These heaters are good at absorbing as well as dispersing heat energy. I tried this fix. The problem is it stays No Error for some time and again it goes to retryable error. Any inputs? Even if i start the writer through command prompt, the backup operation stops it. Did you ever resolve this? Having the same issue for a AG with nodes that are in 2 separate subnets. No load balancers. If your cluster nodes span different subnets, this may be normal. Nicely explained. On my organization servers, VSS services are missing in the services.

Wednesday, May 2, PM. Go to "Task Scheduler" console. Please report back the result. Alikhani Wednesday, May 2, PM. Hello, Rich has left our company and I will be picking up this issue for him. Thanks, Brandon. Monday, June 4, PM. Here is the output of vss list writers from directly after a reboot: Microsoft Windows [Version 6.
Wednesday, June 6, PM. Yes, it will work for a time after reboot, but then will eventually fail once again. The server has actually been rebooted a number of times since the problem began. I just tried kicking off a manual backup to see if that is triggering the failure, but that does not appear to be the case, it is still in a good state.
The issue can also be reproduced by running a shadow copy task, would that also work to help troubleshoot the issue? Can you please provide me the exact error message after executing the mentioned command? Thank You. Here is the output: C Copyright Microsoft Corp. Error: Another shadow-copy creation is in progress, so the current shadow copy c annot be created. Generally, retrying the operation after a few minutes or changing the schedule o f an automatic task should fix this problem.

Alikhani Thursday, June 7, PM. I'm confident that the backup will complete if I stop that service, and will try that as a workaround tonight, but I'd like to first try and identify the problem so that I can use the VSS Writer for SQL. I'll let you know if that allows the back up task to complete.
If so, please tell us which version of SQL Server has been installed on the server? Friday, June 8, AM. The backup completed last night for both partitions.
The version is SQL R2. Friday, June 8, PM. Please do it and report back the result Alikhani Friday, June 8, PM. Yes, that does contain a newer version of the SQL writer. I'll give it a try tonight and report back Monday. Any updates? Wednesday, June 20, AM. Sorry I haven't gotten to this yet, it has fallen in priority since I can get good backups of the server as a whole even if the SQL writer is not working.
I should have an update soon. Wednesday, June 20, PM. Any other suggestions? Saturday, June 30, PM. To do this configuration, on a system with Windows Server R2, follow the steps below: 1. Look at the following figure: 2. Alikhani Saturday, June 30, PM.
