Replication would be used to transfer parts of a database, such as individual tables, also to respond to particular events. Replication can also be used between heterogenous systems. The subscribing system can be both read AND write.

Log shipping would be used when you want a standby database system. You have a second server and load transaction logs at regular intervals. This secondary database can only be read only.

Actually, I've one server A and I want to synchronize with another server like B. All historical data will be on Server B and will be used for reporting purpose only.

The server A will be having 1 year historic data only.

I am planning to implement transactional replication. Can you please provide me a list of Assumptions (i.e. Software/network requirements) and advantages/disadvantages for transaction replication?

And I need to copy daily incremental data from Server A (around 25 tables' data) to Server B.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

a.      Assumptions (including Software/Network Requirements)
The assumptions are that you can reach the other server across the network and that the latency is not too high. Requirements, it depends upon the volume of traffic. There is no particular requirement on the SQL Server.

You need to be able to connect via OLEDB. If it is another SQL Server, no problem. You can also replicate to different servers (Sybase, Oracle etc) but then you need adapters.

b.      Advantages
Replication has the lowest latency and the receiving system can be writable. It sends data transaction by transaction. Replication can also be used where the data needs a transformation.

c.      Disadvantages
You need to set up the replication by creating a publication and a set of articles. That may take a bit of scripting to maintain. Log shipping is definitely easier to maintain and *ALL* changes are transmitted.
