Via the wizard 10 seconds, but it would more likely be constrained by how long your log backups took

Hi, what is the problem you are trying to solve? The lowest I have ever seen in a production environment is every 5 minutes. Probably, the most common frequency setting is every 15 minutes (the default). Of course, at that low setting of every 5 minutes, you will have many transaction log backups, many copies, and many restores occurring. Also, the size of the transaction log backups which will be log-shipped should be smaller due to the increased frequency of the backup portion of the process.

Thank you sir,

I have replicate data from one server to another, and my log shipping time is 1 hour, so whatever i have transferred data from one server to another it reflected to another server after one hour, so i have to reduce that time, so with in minimum frequency i have to reflect that data,

Is anymore suggestion for me?

I think Andrew would agree also, what is your RTO; Recovery Time Objective?

The recovery time objective (RTO) is the targeted duration of time and a service level within which a business process must be restored after a disaster (or disruption) in order to avoid unacceptable consequences associated with a break in business continuity.

How much time does the business give you to have the secondary database available and ready for connections from the application?

Also, what is the Recovery Point Objective, the amount of data that the company is willing to lose during the log shipping operation. The answer is always zero, but zero is not attainable this way (or really, any other way with 100% assurance). 15 minutes? 5 minutes? That number also determines how often you should be shipping the logs.

In our business we transfer data from one server to another i.e secondary with in one hour using log shipping, so ROT is one hour, so with in one hour whatever updated data comes we have transfer into another secondary server database to avoid disruption ,and also make easy to access in read only mode
