Understanding Personal Computer Backup Solutions

By Jocelyn Davidson


A backup involves copying of data in order to restore it in the event that the original is lost. In simple cases, it is enough to copy individual files from their original location to other storage media. If there are ongoing personal computer backup solutions, it is necessary to block updates as long duplication is in progress. To limit the time when updates occur is done in two steps. First, copy the data to a fast medium such as a hard disk. Then copy data from this disk to the destination medium.

The activity is a key aspect of managing a computer: in case of failure, tampering or theft. You ensure that there is a copy, thus ensuring redundancy of logical or physical data. So if you have a dedicated or special software included in the operating system, the copying is almost always set automatically and normally carried out based on the set frequency (for example, once a day or a week), and other advanced settings if made available by the software used.

The data is encrypted and then transmitted over an encrypted tunnel on the Internet to a professional data center. Benefits include large capacity and low cost of ownership and require no special hardware. You should ensure that data is adequately encrypted (448 bit is currently the highest), and the information is encrypted both during transport and storage. An online copy is stored on a server accessible via the Internet. An online variant allows you to restore data without any equipment other than an Internet connection.

The media on which the copying is performed must be approved for the procedure, and they must be regular checks and replacements. They must also be kept in accordance with corporate security policies, for example, but not limited to privacy issues. Several new services on the internet allow you to back up accounts and data of users of social networks.

This is almost a prerequisite for the expansion of online backup solutions, as all data is transferred over the Internet. One must study the market and ensure that the supplier manages data in a proper, competent and confidential manner. What happens to data in the context of bankruptcy and crashes in addition to how the supplier restores backups.

The incremental process includes all files added or changed since the last duplication (full, incremental). An incremental variant is less rapid than differential; may take a longer time because you need to restore from the last full copy and then add in sequence all the incremental backups. Remote backups perform data backups through the Internet to an appropriate server connected. In the majority of cases, an appropriate software is used.

Portable hard drives with external connection USB and USB flash drives (usb-stick) have taken the place of floppy disks that are no longer in use due to poor reliability and limited capacity. You can also back up continuously using services such as online backup or the backup appliance which are instruments that allow this type of operation through agents.

The differential is useful, in particular, for large files that require a full copy, such as corporate databases. Compression is obtained by algorithms of data compression (such as those used by the most popular programs, such as WinZip, WinRar, WinAce) before they are stored on fill-in media, or through deduplication.
