When using a virtual private server, or VPS, for business purposes, you may be interested in knowing how you can backup the data that you are collecting on that system. Whenever work is being done in a digital environment, we must give credence to the possibility that something may go wrong with the data that we are creating and storing. Having a backup is the best way to ensure there will be no problems if something goes wrong with the VPS. Here is our detailed guide on how to backup your data when you are using a VPS.
Comparing Redundancy to Backups
The two terms that we often hear when it comes to backing up VPS data are redundancy and backups. But these two words are not the same, even though they are often used interchangeably. Redundancy for data means that if one set of data is unavailable, lost or corrupted, there is another set that will immediately take its place. The idea behind a redundancy is that if you have some business processes that are dependent on VPS data, a possible loss or lack of access of that data will not damage the processes, as a redundancy is in place.
The problem with a redundancy is that it often does not have a fall back option. Let us say that if you are mirroring one of the RAID storage setups, you will have a perfect mirror that can replace RAID 1 if there is any problem. However, your mirror is not taking into account the possibility of the entire system or machine failing. That is where a backup becomes necessary.
Backing Up VPS Data
When you use a service such as www.iozoom.com for your cloud VPS needs, you will need to ensure that you have a backup system in place. The idea behind these backups is that you are creating copies of your user data, application data or the entire machine in some other location. If you want to achieve a backup that is seamless and efficient on your VPS, we believe that a file-level backup is the way to go.
With a file-level backup, you have two major options at your disposal: CP Command and Rsync.
- CP Command: With this command, you are telling the Linux machine on your VPS to create a full copy of your hard drive onto another hard drive that is connected to the system. When the backup is done, the drive is unmounted and it can be used somewhere else.
- Rsync command: This allows for more flexible local backups. The great thing about rsync is that it can not only perform local backups, but also remote backups. It is just a matter of having the right inputs when you are using the rsync command, and the process will be done automatically.
If you are going with a cloud VPS provider, it is best that you speak with them about the functionality of the cp and rsync commands, and the possibility of local and/or remote backups.
