For those who work behind a computer everyday, it can probably never be stressed enough that a full data backup is required. A data backup refers to the copy (or copies) of original data that can later be used in the event of data loss. The primary purposes of a data backup are to restore a machine to its original state following a disaster, and to restore a number of files that have been corrupted or even accidentally deleted.
Although a backup can save one the trouble of creating loads of lost data from scratch, it still is the last line of defense against data loss and is probably the least convenient of solutions. This is because a backup will not necessarily save a copy of all the data stored on a computer. What it does is it creates a mirror image of primary data that is essential in bringing back a damaged computer to an operative state. Data capacity that is required to do this is quite considerable and it may even be complicated.
However, regardless of how the data is backed up, there must be some sort of medium required for the backup. This may include hardware such as Hard disks, Optical disks, Floppy disks, USB drives, Memory Sticks, Compact Flash Cards, etc. One increasingly popular medium for backup storage is the Internet. This sort of backup can also be referred to as a Remote Backup.
People keep on chanting data room, data room in their bid to use the internet on mobile phones for their pleasure even if it is turned for just 5 minutes for security reasons.
Backing up files is critical and has to be done as quickly as possible. It is advisable that any data created or updated must be backed up almost immediately. For most individuals, the most effective way to back up files is to just copy them onto another storage medium. Portable Hard Disks are easy to come by and are quite affordable. These disks can be used mainly for storage of particular, if not all, files that are deemed important. The Hard Disks can then be stored in a safe and preferably cool, dry place.
At present, companies have also included terms and conditions within their policy to include the backup of information vital to operations. For some companies, one of the most effective ways to backup is to have an onsite and offsite “storage vault”. This basically means that one copy of a particular company’s data is held within the premises and another copy is stored on a server that is located outside the physical location of the company. This has proven effective for data-heavy companies, especially those whose businesses involve the online development of information in text and graphics, such as website companies.
Of the many back up options, one only needs to keep four things in mind in order to save storage space as well as time. Firstly, only the most important of data needs to be backed up. Second, the backup strategy must be just as useful as the restoring process. Third, storage of original data and its copies within the same vicinity is not advisable. This is because of uncontrollable events such as fires and electrical surges that may damage all of the data within range. Lastly, automated backups are more convenient because there is room for human error when performing manual backups.
