You finally have your backup strategy all mapped out and ready to implement. Now you need to find out where your file backups will securely live. The basic rule of thumb is to not store your backups on the same device where your data originally lives. For instance, backups take up a huge amount of space, and if you are storing your production files with same space as your backups – you are going to run out of space. Ideally, you would want to keep them separate so you can have dedicated space for your production files versus your backup files. Trust me – you will save yourself a few headaches at the end of the day.
Secondly, if something were to happen to your computer or server that stores your production files and your backups are stored in the same physical place – you will unfortunately lose both; causing a major catastrophe. Also, you could suffer a major security breach, hardware failure or a power outage that would leave your server unusable. The main objective is to eliminate any single points of failure in your environment for total protection. Having a dedicated device for storing your backups should do the trick.
The first type of backup media is – Tape. Tape backups used to be the most popular ways of storing data around the late 90’s and early 2000’s but is fading away because you now have more convenient backup options. There are a few positives for utilizing Tape backups. You can store a massive amount of data; especially for archival data. The downside is it’s not flexible and takes a long time to read and write data to tape. Keep this in mind when you are planning your backup strategy.
Next backup media is “disk-to-disk” backups. Basically, you are saving files from one server to another server. The backup server usually has a magnetic drive because they are less expensive and hold more data. Magnetic drives store more data than SSD’s, but SSD drives operate a lot quicker. The downside is that SSD’s are more expensive.
Lastly, you can use the cloud as a viable storage media. You can take your backup files and ship them off to your cloud storage. If there is a total disaster with any physical device on your environment you can still get to your backups because they are stored, safely, securely and redundantly in the cloud. Now the drawback to using cloud services is in the event we need to restore data you will have to download the backup files from your cloud storage provider. This can take a while depending on your internet speed and where your cloud instance is located.
When you are dealing with backups, you now know three types of backups, the method of backups and now you have something else to consider in “where” you will store your data backups, and the different media available to you.
