LET'S TALK ABOUT BACKUPS AND SAVE INFORMATION


SHOULD I BACKUP MY COMPUTER AND FILES?

Making backups is much easier and less expensive than trying to recover files from a broken hard drive. Not to mention if your hard drive has been lost, damaged, or stolen, backups are the only way that you can recover the data that was on them.



THREE KINDS OF BACKUPS

There are many ways to back up your files. Even manual copies (like saving a copy to a USB drive) are a kind of backup, they just aren’t a very good kind, because you have to do it manually, you have to do it repeatedly, and you have to manage things like deleting and renaming files. A good backup system is as easy as possible (so you’re more likely to use it) but the best backup systems automatically perform incremental backups so you don’t need to think about it or remember to do anything about it once the system is set up.

1.    A BOOTABLE BACKUP (OR “CLONE”): A "bootable backup" (sometimes called a "clone") is like a spare tire for your car. If you get a flat tire, a spare will let you finish your trip or at least get you to the point where you can get more help. A clone is a complete copy of your computer’s primary hard drive (sometimes called a "boot drive"). If your computer’s primary drive died tomorrow you could hook up the clone, reboot your computer from it, and have immediate access to not only all of your files but also all of the software you use, including all of the settings and configuration changes that you have made. If you are in the middle of an important project or just don’t have time to replace the boot drive immediately, a clone can really save the day. A clone also has a copy of all your files as they were when the clone was last updated, which means that if you accidentally deleted a file, you can copy it back from the clone to your boot drive.

Things to consider: expertise level, buy a software, run frequently, what and how to backup



2.    EXTERNAL BACKUP DRIVE: You can also use an external hard drive to create an archive of your changed and deleted files. An archive is different from a clone in a few ways: first, it isn’t meant to be a bootable backup; second, it isn’t limited to a "snapshot" of your entire drive at one point in time. Instead, it creates incremental backups, which keep up with you as you work.

External drive backups are mainly intended to provide a backup of your personal files, especially irreplaceable things like pictures. Instead of looking at your entire hard drive, this type of backup only looks at certain folders, such as your home directory. The archive part of this type of backup means that if files are on your primary hard drive are changed (or even deleted) you can go back to undo the changes and even recover those deleted files. If your computer dies you can simply plug the external backup drive into a different computer and immediately have access to all of your files, as well as the history of changes and deleted files.

Most external drives for PC come with their own backup software. If you use a Mac you can buy an external hard drive and use Time Machine, which will run every hour and check for changes. It will save hourly backups for the previous 24 hours, daily backups for the previous month, and weekly backups for previous months. Time Machine is easy to use, both for backing up and restoring files, but it does have drawbacks. Having to connect an external hard drive to your computer is inconvenient for laptop users who want to be able to move their computer around.

One advantage of a local archive is that there is no monthly or annual fee, and you have immediate access to all of your files in case your computer dies. However, the amount of file history (that is: how far back you can go to get previous versions of files, and how many deleted files you can recover) is limited by the size of the external drive. If you need to get a file back from yesterday or last week, you can probably do that. If you need to get a file back from several weeks ago, you might be able to or you might not, depending on how much other data is being backed up.

Last but not least: an external backup drive is still a hard drive, subject to wear and tear, it will eventually need to be replaced, at which point you will either have to migrate your data to a new drive (if possible) or start from scratch.

Things to consider: very cheap compared with other types of backups, not necessary software and can be freeware, manually and takes a lot of time depends in how much info do you own, can be weekly, monthly and every three months the backup jobs



3.    CLOUD BACKUP: Having a backup (or two) next to your computer is a good start, but it still puts your data at risk for theft, fire, or other disaster. Your best protection against that type of loss is to keep another backup somewhere else. While you could make a clone and bring it to a friend’s house or your office, or even put it into a safe-deposit box, chances are that you would not remember to keep it updated because it would be inconvenient.

In fact, cloud backups are the easiest kind to create and maintain. To get started you simply need to create an account, download software, run it once to enter your account information, and (optionally) set any preferences that you might want. After the initial setup you don’t need to do anything, the software will automatically keep your computer backed up any time it is turned on and connected to the Internet.

Behind the scenes a lot is going on with your cloud backup. First your files are encrypted so no one else can read them. Then they are copied not just to one drive but to lots and lots of drives. One of the main benefits of cloud backup is that the "cloud" is made up of many distributed and redundant computers and drives, so the loss of any one will not cause you to lose any files. Once they are uploaded, you never have to worry about uploading them again unless they are changed. Even then, changes can be sent much faster because the software is smart enough to know what is different and only send the changed data.

Things to consider: price and provider, size of your files and internet connection, NOT all the information can be uploaded to clouds, how often can be or has to be?



WHICH BACKUP OPTION SHOULD YOU CHOOSE?
Ideally, a 3-2-1 backup strategy is recommended, this means 3 copies of your data, 2 on-site but on different mediums, and 1 offsite. A good way to start is by having the original copy of your data, along with an external hard drive or clone at home, and an off-site solution like an online backup provider.

LET’S TALK ABOUT - NETWORK FORENSICS

LET’S TALK ABOUT - NETWORK FORENSICS BASIC CONCEPT Network forensics is a sub-branch of digital forensics relating to the monitoring and analysis of computer network traffic for the purposes of information gathering, legal evidence, or intrusion detection. Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. Network traffic is transmitted and then lost, so network forensics is often a pro-active investigation. Network forensics generally has two uses. The first, relating to security, involves monitoring a network for anomalous traffic and identifying intrusions. An attacker might be able to erase all log files on a compromised host; network-based evidence might therefore be the only evidence available for forensic analysis. The second form relates to law enforcement. In this case analysis of captured network traffic can include tasks such as reassembling transferred files, searching for keywor

LET’S TALK ABOUT PC AUDIO SPEAKERS Computer speakers are one of those PC accessories that are almost essential; and you can spend anywhere from $10.00 to $1,000.00 for quality PC speakers, depending on your budget.   There are tons of tons of speakers with features and different prices as we know. But as I always say: WHAT and HOW is what I am looking for. For sample: I have this one in my office and works properly, the only disadvantage is that has no RADIO and only can be played with micro SD and plugged to my computer. And only pay like $20-$25. USB charged and the battery longs for 6 hours. https://www.energysistem.com/en/products/music_box/music_box_series_/42198-energy_mini_music_box_z100_r_black Here there is some thoughts and share some personal ideas about this topic. I enjoy listening to music a lot, and because my computer is the main source for my digital music collection, a decent speaker system is essential. Expensive is not alway

COMMON TYPES OF NETWORK & COMPUTER ATTACKS Without security measures and controls in place, your data might be subjected to an attack. Some attacks are passive, meaning information is monitored; others are active, meaning the information is altered with intent to corrupt or destroy the data or the network itself. Your networks and data are vulnerable to any of the following types of attacks if you do not have a security plan in place. EAVESDROPPING In general, the majority of network communications occur in an unsecured or "cleartext" format, which allows an attacker who has gained access to data paths in your network to "listen in" or interpret (read) the traffic. When an attacker is eavesdropping on your communications, it is referred to as sniffing or snooping. The ability of an eavesdropper to monitor the network is generally the biggest security problem that administrators face in an enterprise. Without strong encryption services th
