Hi folks,
I'm having an issue with log shipping. What has taken 2-5 minutes in the past is now taking 20-40 minutes which is no good really. File sizes have not increased.
I've run the log shipping with a global trace on 3004 & 3605.
The issue appears to be the step Restore: Transferring data to <db_name>which is taking about 90% of the process time in the Restore job on the secondary server.
I'm unsure what this element does in the restore, so am looking for further details / suggestions / where to look for issues.
I'm providing the log from the trace below,
many thanks
Stuart
