Backing Up Your Data
If you only have a single copy of your data, you’re vulnerable to losing it. A hardware failure or theft can lead to losing hundreds of hours of work or irreplacable photos.
“Don’t worry— I have a Time Machine backup," I hear you say. Having a Time Machine backup is a good first step, however, you’re still at risk in cases where you lose both copies in a house fire or if both your laptop and Time Machine hard drive are stolen.
Hard disk drives are also prone to failure.
One solution is to store a copy of your data remotely in the cloud. Storage services will also have redundancy measures in place to avoid data loss when hard drives inevitably fail.
A good rule to follow is the 3-2-1 rule for backing up your data.
The 3-2-1 rule for backup goes as follows:
- Have at least three copies of your data
- Use at least two different types of media for your copies
- At least one of your copies should be offsite
Backing up your experimental data
Following the 3-2-1 rule, your sequencing data for your study should have at least three copies. A typical case would be:
- one copy on a external hard drive stored in the lab
- one copy on the volume attached to the server where you’re doing your analysis
- one copy in Mediaflux labeled with appropriate metadata
Cloud-based automated backup services
Having a remote backup for your computer is also a good idea. Services such as Backblaze can automatically backup your computer, but they also have a monthly subscription fee at around $5 a month.
An example of using the 3-2-1 rule for backing up your laptop would be:
- one copy on the SSD in your laptop
- one copy on a HDD with Time Machine backups
- one copy in the cloud using a cloud backup service such as Backblaze
