Backup is a computing term. It describes the simple process of duplicating files or data sets.
In short, making a backup means creating a safety copy you can recover in an emergency.
Backup meaning: what it is and how it works
Anyone who works in this field knows how important data backup is,
whether on a PC, tablet, smartphone, GPS navigator or any other electronic device that runs software.
It’s a standard procedure, to be carried out as part of routine maintenance.
In other words, something to do regularly to safeguard information you absolutely can’t afford to lose.
So how does it work?
There are two basic steps:
- copy the data;
- store it somewhere other than the original source. Everyday users most often rely on external hard drives or USB flash drives; more advanced users choose the cloud or a NAS.
Naturally, you only restore the data when necessary.
Types of backup
Now that we’ve explained what a backup is, the next question is a different one.
What are the main types in use?
Let’s find out:
- Full As the name suggests, this is a complete backup of all the system’s files, folders, documents and data. Keep an eye on the storage capacity of the medium you use, though: it may not be enough.
- Differential Copies the items that have changed since the last full backup.
- Incremental Saves the items that have changed since the last successful backup of any kind.
- Cold The data is copied offline, so the database is unavailable to users, even for updates.
- Hot Also called a dynamic backup, it is performed while the database remains accessible to users.
What incidents can cause data loss?
As you’ll have gathered, a backup is essentially about prevention.
With just a few minutes of work you can safeguard your personal (or business) data. There are no obvious drawbacks, only benefits.
If you still have doubts about how useful it is, consider this.
Danger is always just around the corner.
Every day you risk losing important information because of:
- human error
- cyberattacks
- technical failures or malfunctions
- equipment theft
One last tip: if you don’t know where to start, don’t improvise.
Rely on real professionals.
