Single or multi tier backup which is best?

Backing up enterprise data is extremely important these days, especially, when data loss issues like ransomware are on mounting prowl. Thus, IT Managers and decision makers should think ahead and invest in the safety of their business data before an issue arises in which data could go inaccessible forever.

This is where having a backup copy of data shows its prominence and that’s due to the fact that it would likely cost more money to recover lost data that it would to back it up in the first place.

There are different backup solutions depending on your needs, such as a single or multi tier backup and both have their own quality and reasoning. So, this article will attempt to expose the difference between them

Single tier backup- As the name itself suggests, only a single machine is involved in backing the data. This machine reads from the source and writes to a target appliance. This backup option is well suited for environments where backup source and target are close to each other. Single tier backup appliances are not accessible via internet without some help from a third party.

A single tier backup must be used by a single user environment and both the source and the target must remain connected to each other. Synchronization of backups with multiple machines must be done on a manual note. Most single tier backup repositories do not allow sharing of files via internet.

Multi Tier backup- In this backup variant, a single machine reads from source, while another machine writes to destination. This backup solution is well suited for environments where source and destination are far apart and are connected through internet. Multi tier backup only transfer and backup the modified part within a file, which is known as delta or delta backup. The backup up file can be accessed from anywhere, via a web browser.

In a multi tier backup environment, several users can backup to a single repository. The source machine can be dynamic meaning it can be moved relative to the destination. For example, users can backup data from their laptops to a central server. This backup arrangement can also serve as a file sharing resource and has the ability to synchronize multiple machines automatically.


If you are looking for local backup where the source and destination are close by, single tier backup is the way to go. On the other hand, if you are looking for backup where the source and destination are far apart, multi tier backup will be a better choice.
