I personally don't see any disadvantages to data replication. My company uses a data replication software - HVR, if you're curious - to allow several members from different locations to access real-time copies of our main data at the same time. You can use it for that, as it serves this purpose perfectly, but another advantage of data replication is that it serves as a backup if something goes wrong at some point. It's better than regular backup, actually, since it's done almost in real-time and you can access the most recent copies asap. So if you have a bigger organization, I don't see any reasons why you wouldn't want to be replicating your data. Just make sure the software you pick is compatible with your database, btw, as some have limited reach, but other than that you can enjoy many benefits.

As with every action for your data, data replication does have its benefits as well as disadvantages. If you ask me, the advantages are more.


The advantages of data replication are:



  • Creating a ready-to-access and always-available copy of your data

  • You can enhance the resilience of your system by storing data at multiple sites across the network

  • You can be sure that data modifications are reflected in the copies, unlike backups that are pretty much static replicas




And as for disadvantages:



  • Some data replication softwares support too few databases so you have to learn whether yours is among them before making a deal

  • Compared to a centralized system where your data is located in a single place, you'll need more storage
