We have a web server that uses AD LDS for managing tabs, roles, security, etc. running on Windows Server 2016.
I am currently having an issue backing up AD LDS using the DSDBUTIL. It has been running for years but has recently started having problems and fails to write the backup either to a network share or a local folder (I have tried both during troubleshooting). Also I cannot correlate when it started failing to any server or application changes.
When attempting to run a bat file that contains the DSDBUTIL command, the ADAM (INSTANCE-NAME) Writer reverts to the FAILED State as shown below.
Writer name: 'ADAM (INSTANCE-NAME) Writer'
Writer Instance Id: {8bbe9162-20e3-44ec-9ee3-2a30f439a64e}
State: [11] Failed
Last error: Non-retryable error
The writer also reports the following error when trying to do the backup:
A VSS writer has rejected an event with error 0x800423f4, The writer experienced a non-transient error. If the backup process is retried,
the error is likely to reoccur.
Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.
If anyone can point me in the right direction it would be appreciated. We also have a replicated instance of the same web server and the backup using DSDBUTIL works fine from there. I have also tried using Windows Backup but it also fails, causing
the ADAM (INSTANCE-NAME) Writer to fail again. I have to restart the ADAM (INSTANCE-NAME) service to place the writer back in the READY state.
Thanks
