Diy-Computer-Repair can help!

You could use one of the following devices to do a data backup on a daily, weekly, and monthly basis.

Tape Drive<

CD Rom(rewriteable disks)

Flash drive

External hard drive.

Each of these devices has pros and cons for backup. I will list them here:

Tape:
Pros: Large capacity, can be encrypted, fairly long life.
Cons: Expensive, both the drive and the media. Complicated.
CD ROM or DVD:
Pros: Medium to large capacity, extremely long life, easy to store, can be encrypted.
Cons: Complicated procedure, read only once the data is written.
Flash drive:

Pros: Cheap, small, easy to use. Can be encrypted.
Cons: Low capacity, easy to lose or to steal, easy to erase!
External hard drive:
Pros: Large capacity, easy to use, can be fairly small, medium price. Can be encrypted.
Cons: Easy to steal.

NAS - Network Attached Storage
Pros: Large capacity, this is a workstation that has the hard drive or volumes shared for access by network users.
Cons: If you use a Windows Operating System such as Windows 2000, XP, or Windows 7 for the NAS then only 10 connections are allowed at time. Cheaper than a full Server.

Scheduling:

when you need to recover your data after a catastrophic event. There are different ways to backup your data.

Manual:

You go to each folder/directory and copy all the contents to your backup media.

Automated:

You use a program to search your computer(s) for any document that has changed during the given period. You can set the program to do daily, weekly, monthly, or full backups of selected folders/directories and select the file type to backup. You don't need to backup programs or their associated files. This type of backup will be discussed in the next section.

This process is explained in more detail in the Self Computer Repair Manual.
