5 ways to safely backup data

Backup data is the best way to protect your data. This article will give you five ways to back up different data for you to choose depending on your circumstances and conditions:

1. Memory stick

Memory stick (also known as USB flash disk) is a device that helps to quickly backup by its superior features in data transmission. Types of memos that communicate with the computer via USB port. Modern computers have USB 2.0 communication ports that allow data transfer speeds of up to 480 MB / sec (old computers with USB 1.0 ports only allow transfer rates of up to 12 MB / sec). With this advantage, backing up to a memory stick will be quick and convenient.

However, one of its major drawbacks when used in backups is small storage space. Although today there are different types of memory cards in the market (more than 2 GB), most consumers prefer only between 512 MB and 1 GB. Therefore, if you use a pen, you should only back up important data types such as personal documents, work .

2. CDs and DVDs

Backup to CD is a very popular way to use today. With a few hundred thousand dong, you can buy a CD burner right away and the price of blank CDs for recording is also very cheap, only a few thousand dong. Each CD can store about 700 MB of data and it is not a problem to use multiple CDs for backup. Moreover, all computers now have at least one CD drive.

At a higher level, the DVD will surprise you with your storage. To back up 7 GB of data, you need 10 CDs, while only a double-layer DVD disc or two-layer DVD is enough for you. However, to use the DVD for backup, you must have a DVD burner and DVD burning discs. It requires a relatively high investment compared to CD burning drives and CDs. The simple problem here is that the distance between them is very large, so most consumers still prefer to choose CDs.

3. External hard disk

This is a new way of backing up data but very dynamic and effective. To be able to perform backups in this way, you need to have a hard disk and a hard disk box called HDD Box.

Accordingly, the hard disk will communicate with the computer via the USB port of the hard disk case. At this point, its operation is the same as a memory pen and you can easily back up. Its storage capacity is the capacity of the hard disk in HDD Box. Therefore, if you want to store a lot, you need a hard disk with a large capacity and of course the investment cost will also increase with the hard disk capacity.

4. Internal hard disk

With this backup, you need to have a new hard disk attached to the inside of the case along with the current hard disk. The difference from an external hard drive is that the internal hard disk is permanently connected in the case, like adding another hard disk to the computer, ie, not portable compared to an external hard disk. From there, you can back up the necessary data from the current hard disk to the new hard disk to ensure safe data loss.

At a safer level of data backup, use RAID (Redundant Array of Independent Disks), namely RAID 1. To do this, you need a new hard disk with capacity. equivalent to the current hard disk. Accordingly, all data is stored on two hard disks

This will be identical. In the computer system, you only see a single disk. When a disc has a malfunction or failure, the other disc continues to operate normally.

5. Store online

The online storage services that now offer a new way of backup are also very effective for all computers with an Internet connection. Investment costs for this form of backup are acceptable, you only have to pay the Internet connection fee and pay the online storage fee if using fee-based services. With free services, you can only backup a limited amount of data. Moreover, Internet connection speed will be a very important issue if you want to backup in this form.
