While trying to run the backups using dedupe option with SDLO 7.5 the backups are failing with the following error
FAILED to copy to Network User Data Folder. Dedupe engine offline
How to troubleshoot:
1. Confirm whether all firewall settings on both Dedupe Storage Location (DSL) server and DLO client are disabled.
2. Confirm the connection to "http://[DSL server name]:8080" and "https://[DSL server name]:8443" on Internet Explorer of DLO client.
[DSL server name] is a server that is running the service "Mindtree StreSmart Dedupe Server" and the process Tomcat7.exe.
"StoreSmart Dedupe Server Status: (20159) Active." needs be displayed on Internet Explorer.
3. Confirm whether "Domain Users" is added to "Allow log on locally" in Group Policy Management.
When DSL exists on Domain controller (DC), use "Default Domain Controllers Policy".
When DSL exists on Member server, use both "Default Domain Policy" on DC and "Local Security Policy" on Member server.
If the job works correctly by adding "Domain Users" to "Allow log on locally", change from "Domain Users" to a specific Domain User name because of the security reasons.
4. Confirm the path of Storage Location is different from one of DSL.
The path of Storage Location must not be same as one of DSL.
Disable the dedupe option from the profile.
