Tape Drives, CD or DVD ROM Drives for Data Backup, the different data backup devices.
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.
You should review how much data you generate daily, weekly, and monthly. If
you can backup your data at the end of each business day the better it will be
when you need to recover your data after a catastrophic event. There are
different ways to backup your data.
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.
