Log Shipping Stops after 3/4 days
Ive setup log shipping for two of my databases to a server so I can run reports against the 2nd server. Once I set it up, the process runs quite happily for 3/4 days then the restore process of the logs to the secondary server starts to fail. The copying of the files is still working its just the restore side which is failing. The only way to get this back up and running is to remove the log shipping options and resetup the process.
How can I identify the problem? Ive checked the job history of the restore process and this is the error.

Ive gone through more of the job history and found this which could have something to do with the issue.

Looks like the process is out of sync?

Sure, I can leave the logs as long as you like whats the best setting for this?
Once the set time of retention has elasped, will the process fail at that point?
What I want is to set it to a value which will cause the process to fall over.

I think you need to determine the best value by yourself.
What I can suggest is that you need to observe when you database is in use - how long does it take?
Next you need to determine how long does it take for your server to restore unrestored logs.
You need to keep logs as long as they are not restored.
Maybe scheduling reports execution to low transaction time in your enviroment will help - if you can schedule them like that ;)

Let me correct myself:
You need to keep logs at least as long as they are not restored ;)

Ok, that makes sense. I run a report on Friday at 1 and its at this point the log shipping falis. Im going to change it so the log shipping doesnt take place during that time.
ASKER
Right, yes - that makes sense in terms of keeping the logs.
Im going to set everything back up now and test.

Thank you.
When your log shipped database is used in some queries no logs can be restored. Maybe this is your issue?
I'd suggest you to think about mirroring as an option. You can mirror your database and in mirror server run snapshots against mirrored db. Then you can generate raports using snapshot.
Take care,
