Logging & Traces

CxLink Backup Settings will log all the information related with a backup or restore execution in its own log file.

Topics

Agent logs

You can find agent logs to help you troubleshoot errors and failures in the following locations:

File	Path	Description
Local log	/var/log/emory/SID.log	Stores all information related with the emory agent execution and the backup/retore process. (SAP HANA backup/restore process will be stored in the global log)
Global log (HANA only)	/usr/sap/SID/SYS/global/hdb/opt/log/emory.log	Stores all information about the backup/restore execution in a single or multihost environment
