Remote Data Backups Versus Local Data Backups - Advantages and Disadvantages

These days, technology is growing much faster than what is used to be. Almost all the businesses are having their own online webpages and data storage area where they can perform marketing and communications with their customer via online store front. Whether your business is big or small, data backup is vital for protection of your data and it maintains your business's security. Backing up data can be done either remotely using file servers, or locally using DVDs, pen drives, tapes, external hard drive or another part of local drive. The advantages vs. disadvantages of local backups and remote data backups are listed below.

Advantages of Local Backup

A very effective way of data backup is downloading data into storage devices such as DVDs, CDs, pen drives, external hard drives all of which are portable, and also a part of local drive, from where data could be easily retrieved if required. Local backup is advantageous as it is quick and easy. Also backup softwares are available now for your computer and its files. If your computer crashes, your files can be retrieved from these storage devices. This method is used by small business people as well as individuals.

Remote Data Backups Versus Local Data Backups - Advantages and Disadvantages

Disadvantages of Local Backup

Though local backup is quick and easy, it also has some disadvantages. You never know when a calamity like fire or flood would happen. Such a calamity will destroy not only your computer but also the storage devices with your data backup. Also it's not unusual that sometimes we lose memory; so you are likely to forget where you kept the pen drive, thereby losing the files.

Advantages of Remote Backup

Remote data backup is gaining wide use now due to some advantages. When your data backup is secure at a safe location away from your office you can rest assured that whatever may happen at your workplace your files are secure. Almost all big concerns go in for this method. With the advent of worldwide outsourcing, remote backup has gained popularity since the data sourced from abroad are secure at their own base in their country, while the data is used by their offshore offices.

Disadvantages of Remote Backup

The disadvantage of remote backup is data transfer speed. Remote backup may take considerable time according to the speed of the transmission devices. High speed LAN can transmit data rapidly while other devices could have their own problems due to upload limitations and firewalls.

It is advisable to utilize both the methods so that you can be sure of your data being secure despite all odds.

Excel - Combine Data From 2 Different Spreadsheets With a VLookup

A vertical lookup is an extremely useful - but little-used - feature of Excel. It allows you to link data arranged in a table to data in your spreadsheet by matching a field contained in both the table and the spreadsheet - for example: an i.d. number, a last name, a zipcode, etc.

For example, say you have a spreadsheet that lists your employees and their home addresses, and another spreadsheet that lists your employees and their work departments. Suppose you want to put that information together - have one spreadsheet containing both the home address AND the department information. Vlookup will use a field that both spreadsheets have - in this case the employee name - and look up the information (the department) in the second spreadsheet and display that information (the department) in the first spreadsheet.

Here's how to do it:

Excel - Combine Data From 2 Different Spreadsheets With a VLookup

Copy the second spreadsheet onto a worksheet in the first spreadsheet, so that the information is all in the one Excel file, but on different worksheets (tabs). Sort the data on the second spreadsheet in ascending order, on the employee name field. Now you want to look up each employee's department and put it on the spreadsheet with the employee's address.

On the first worksheet (with the employee name and address), type in a header for Department.

In the cell under the header, type in the formula for vlookup: =VLOOKUP(lookup_value,table_array,col_index_num,[range_lookup]) Look_up value is the cell address of the field the two worksheets have in common - in this case, the employee name.

Type a comma (very important!)

Table_array is the table that contains the department name for the employees - in this example, you've placed it on another worksheet (tab) in this file. To enter this information into the formula, go to the worksheet the table is on and select the entire table (you can hold the mouse button down and run the cursor over the table: Excel will enter it automatically). Turn this address into an absolute address by typing a $ in front of the letter and the number of the cell address - for example, A1:B156 would become $A:$B6.

Type a comma (very important!)

Col_index_num is the number of the column in the table that contains the information you are looking for. In this case it's "2" because the department information is in the second column of the table.

Type a comma (very important!)

Type FALSE. This tells Excel to return a department from the table only if the name is an exact match. If you type TRUE, if there is not an exact match, Excel will return the closest one. Type a close parenthesis ) to end the formula, and press Enter.

You will be returned to the first worksheet. The cell containing the vlookup formula will now display the department for the employee. Copy the formula down for the rest of the employees. You've now successfully combined the information from the two separate sheets onto one sheet, linked by the employee's name.

External Hard Drive Data Recovery - How to Recover Damaged and Corrupted Data From an External HD

Recovering corrupted and tampered data from external hard disk drives is one of the most common tasks which require us to spend laborious hours on it. Though external hard drive data recovery is a tedious work, it is no longer termed as an impossible undertaking. A hard drive has become an indispensable part of our lives as it is used to store all our digital data such as music, pictures, videos etc in it. The consequences of the failure of such external disk drives can be annihilating. Therefore, external hard drive data recovery is a prerequisite to save ourselves from the devastating effects of the loss of crucial data such as financial information, pictures, official documents etc.

Some of the reasons which result in the failure of hard drives are as follows:-

· Due to the negligence of the user, the hard disk can fall of from his or her hand resulting in physical damages being made to the hard disk drive.

External Hard Drive Data Recovery - How to Recover Damaged and Corrupted Data From an External HD

· The hard disk drives may get overheated due to the absence of sufficient ventilation techniques.

The above causes are few of the most commonly appearing faults which makes the task of external hard drive data recovery even more important.

Once a hard disk drive gets damaged, we should not retain the damaged device for further usage as it might result in further deterioration of the system. A repair utility should also not be carried out on the data of a damaged drive as it might transform all the retrievable data to an irretrievable form.

External hard drive data recovery can be carried out easily by making use of one of the available data recovery tools such as Data Clinic, EASEUS Data Recovery Wizard etc.

The working of a data recovery tool can be illustrated by the following steps:-

Loss of data due to virus attacks or hard disk drive damages are considered to be high priority situations which require immediate attention. The various technicians determine if the drive can be accessed using the lab equipments. If the damaged disk can be accessed, an image of all the data on this disk is copied to a new disk. If the damaged disk cannot be reached, the level of damage is determined. The failed or damaged parts can be replaced by the new components in order to perform recovery. The low level data sectors are analyzed carefully by the technicians in the case of logical drive recovery. Ultimately, the data files are extracted by de-stripping the servers containing multiple drives.

Any of the available recover data tools can be used by the people to recover their damaged disk drives. As these tools are innumerous, recovery of lost or corrupted data is no longer impossible.

Which is Faster Wireless Router Or Wired Internet?

It is commonly known by data networking technicians that a wired network for Internet connectivity is faster than Internet connectivity from a wireless router. But what is not commonly known is why. A router is a device that is used to connect one network, such as the Internet, to a Local Area Network (LAN) that has several connected devices such as computers. Wired Local Area Networks commonly use the Ethernet protocol for data communications. This protocol generally has bandwidth speeds from 10Mb/s (megabits per second) to 1000Mb/s with 100Mb/s being the most commonly used for networking computers in most homes and offices. The Ethernet data communication protocol uses full-duplex communication; that is, it can send and receive data at the same time.

Internet Service Providers mostly offer high speed broadband services up to 1.5Mb/s which are defined in terms of the maximum download speed because several common consumer broadband technologies have a slower maximum upload speed.

A router as the name implies, distributes data packets from the Internet to each requesting computer connected to it. This is done in an orderly manner by using high speed electrical switches. The maximum rate at which the router can switch the data packets also determines the maximum speed of operation of the Local Area Network. If you have too many computers connected off the router, the router can become a speed bottleneck. So in theory, if you use a 100Mb/s Ethernet cable to connect to your Internet Service Provider, then your Internet connection will not slow down as most broadband Internet Services for home use peak out at around 1.5Mb/s, and business use peaks out at about 10Mb/s (but shared across many computers).

Which is Faster Wireless Router Or Wired Internet?

With wireless data networks, the most widely used protocol is the IEEE 802.11 standard. This standard has had many revisions over the past few years and the latest is the 802.11n version. The 802.11n version can in theory work up to 300Mb/s whereas the earlier 802.11b version works up to 11Mb/s and the 802.11g works up to 54Mb/s. But wireless routers only provide wireless data connectivity using a half-duplex protocol (either send or receive data but not both at same time) and this makes them slower than wired Ethernet connections. But there are a few other factors that make wireless networks slower than wired networks due to signal and data processing overheads. The wireless signal can be susceptible to local interference from other nearby electrical equipment and this can cause the performance of the wireless network to degrade. When the wireless signal degrades, the wireless router must perform more data error corrections to maintain the integrity of the data and this causes delays in distributing the data to and from its destination and slows down the connection.

If wireless security protocols are also used to encrypt the data, this requires additional data processing to be undertaken that can also limit the performance by introducing inherent latency delays. Hard-wired networks do not need to have the data packets encrypted because they are physically secured in most buildings whereas wireless networks cover areas that are not secured and hence the data needs to be encrypted to secure it from unauthorized users.

For better performance Internet connectivity, use a wired cable if you can because it is physically secure, allows faster performance, costs less, and is not as susceptible to electrical interference compared to wireless connectivity.

In summary, if you use your computer for gaming, voice over IP, or real-time collaboration, then you are better off using a wired cable network connection to the router that connects to the Internet Service Provider.

New Computer - Old Email, or How to Back up and Transfer Your Email

If you have a brand new computer, or are thinking about buying one in the near future, one of the things that you will need to consider is how to transfer your emails from the old system to the new system.

At least once a week in my job as a help desk analyst, I am helping a customer set up Outlook Express or Outlook (there are other email clients that are used, but these two are the most popular) on their new computer. Once we are finished with the setup and they open it up to the Inbox the question is asked "where are my old emails?" The simple answer; "on your old computer". Then of course the follow up question is; "how do I get them to the new computer?"

Easy or Hard

New Computer - Old Email, or How to Back up and Transfer Your Email

The easiest way to do this is to back them up to an external hard drive or a compact disc before you make the switch to the new computer and then copy them over to the new computer in the exact same directory. The harder way is in the case of a crashed computer or the inability to access the files normally. I cover a bit of that in another article called 'Got Backups?' which you can find at my website.

Outlook Express

With Outlook Express your emails/email folders are stored on your hard drive in a directory that is buried way down deep in the Operating System. Instead of me giving you the full path to get there, it's easiest if you have Outlook Express open, click on Tools then Options.

Copy/Paste

Once you are here, click on the Maintenance tab and then click on the Store Folder button. This will pop another window with the location of your emails. Using your mouse, highlight the path and then right click and copy it.

You will then click on the Start button, then click Run, and then right click in the Open box and Paste the path. Click Ok.

This will open another window with your email files. Unless you have added other folders to your Outlook Express, the default folders will be here with a .dbx extension (Folders, Inbox, Sent Items, Deleted Items, and Drafts).

Backup

If you are going to write these files to a CD, you can burn them at this time by using your favorite burning software (providing that you have a CD burner installed in your computer).

To copy them to an external hard drive, you must now connect that device to your computer, create a folder on that drive (I usually call it Email Backups), copy the files from the old computer then paste the files into the Email Backups folder.

Import

Once you have the files copied to the CD or external drive, then you will go to the new installation of Outlook Express and import the messages. It would be nice if you could just copy them to the new OE and be done, but Microsoft doesn't like you to do it that way.

Open up OE and then click on File, Import, Messages. This will open a new window called Outlook Express Import. Choose Microsoft Outlook Express 6 then click Next. Click in the circle that says 'Import mail from an OE6 store directory'. Click OK. Then click 'Browse' and navigate to and select the directory you have saved them to. Click OK. The next window will give you a list of all of the email folders you have previously saved. Keep 'All folders' selected and click Next.

This will begin the process of importing all of your 'old' emails into your 'new' Outlook Express. Once it has finished you will have all of your old emails back! Cool, huh?

Outlook

The procedure to save and then import your emails in Outlook is similar, but different.

To start with, Outlook uses a file extension called pst, or Personal Folder File. Don't ask me why it's called that. Call Bill Gates and ask him.

Export

You will start on the old computer and with Outlook open, click on File, then 'Import and Export'. This opens the Import and Export Wizard. Choose 'Export to a file' then click Next. Choose 'Personal Folder File' here and then click Next. In the Export Personal Folders dialogue box you have your choice of what you want to do. The easiest is to keep the default choice of just the inbox, but if you want your sent items and all the other folders, choose the top item (Personal Folders) and then choose the 'Include subfolders' option and then click Next.

The next window will have a default location listed
(usually C:Documents and Settings'your computer name'Local SettingsApplication DataMicrosoftOutlookbackup.pst). I would suggest following the same procedure as for OE (see above). Then click 'Finish' and let it do it's thing.
Once you have your pst files backed up, move to the new computer and the import process will again be similar to OE.

Connect your external hard drive to your computer or insert the CD into the drive.

Import

Open Outlook, click on File, then Import and Export. In the Import and Export Wizard, this time choose 'Import from another program or file' then click Next. In the 'Import a File' window, scroll down and select Personal Folder File (.pst) and then click Next.

In the 'Import Personal Folders' window, click the Browse button and navigate out to the location of your backed up pst file, choose it and then click Next. Click 'Finish' and it will import all of your messages.

Regzooka Review - Should I Use Regzooka?

Are you wondering if you should use Regzooka? Well, a group of experts and I have purchased a variety of different registry cleaners and put them to the test to see which software is the most effective for our consumers. Regzooka was among one of those registry cleaners that we have tested.

On paper, Regzooka is an award winning registry cleaner that is created by BluePenguin Software, a technology company that is known for creating systems utility tools for removing spyware. Keep in mind that "award winning" should not be a deciding factor when choosing which software to use because most programs like this have won similar awards.

Upon doing additional research on their company, I discovered that they have received a very poor rating in the BBB (Better Business Bureau) Business Review. In fact on September 28th 2010, BluePenguin Software had their accreditation revoked by the BBB's Board of Directors.

Regzooka Review - Should I Use Regzooka?

Now that we have reviewed the facts on Regzooka, let me report to you exactly what we discovered after having purchased and tested this program ourselves.

After the results for Regzooka had come in, we were not surprised when we found that this registry cleaner was classified as mediocre among the other programs tested. This software was a fairly decent and had all the necessary functions to do a thorough scan on your computer, but lacks some advanced options and special features such as the System Optimizer or Evidence Eraser that we want in these programs.

The interface was not as user-friendly as we hoped for. Some features were hidden away and might require a few minutes of digging before you could find them. Novice computer users may not be able to navigate this program as well as advanced computer users, however all the basic functions to perform a computer scan were simply laid out.

One thing that set Regzooka apart from the other programs we tested is its 100% guarantee of error removals. If this software did not clean out 100% of your computer errors, you had 60 days to do a complete refund. This was a nice option, however many other programs also offered 100% 60-day money guarantee if you were not satisfied with the program.

Overall, we give Regzooka 6.5/10 because it is a fairly decent piece of software that could potentially remove all the errors and help speed up your computer performance.

However, within the given price range, there are many other registry cleaners that offer much more in terms of special features.
