In one embodiment, the method includes: Access that can be and often times is controlled by tokens can include physical access to rooms, buildings, areas and so on; electronic access to servers and data files; electronic account access; and so on. Another form of access controlled by tokens is the ability to conduct transactions such as, for example, credit, debit and other financial transactions. Credit cards, charge cards, debit cards, loyalty cards and other purchase-related tokens are used to provide the consumers with ready access to funds.

How Does Remote Backup Work? Our Remote Backup Service works like regular data backup software, with one important difference. Instead of sending backups to a tape drive or other media attached to the computer it is backing up, Remote Backup sends the backup over the Internet, regular telephone lines, or other network connections to our backup servers safely offsite.

It does this usually at night while computers are not being used. Backups can also be done on-demand, any time. In fact, you may even forget its working. With businesses depending more and more on the data stored in their computers, proper backups are becoming much more critical.

Remote Backup accomplishes several essential steps that are often overlooked or done improperly by other backup software - especially in the regular non-automated backup systems.

Backups are done on schedule, reliably. Since Remote Backups are done with automated software usually at night, when nobody is using the computer, backups are always done on schedule. The correct files are backed up. Ordinary backup software is often installed with a list of files to be backed up.

This set of files usually represents the state of the system when the software was installed, and often misses critical files. Further, it often fails to back up files that get added later. Compounding this problem, VERY few businesses take the trouble to reset their backup software regularly to include new files.

Remote Backup solves this problem by constantly reevaluating the computer system, adding files to the backup as needed. Several full copies of files are stored using a sophisticated version control system unavailable in most other backup software of any kind. This is much too important to overlook.

The general definition of "proper" backups requires redundancy.

CA Final ISCA Summary notes

One must keep multiple copies of the same files at different points in their development, called versions. As an example, you should have a different copy of each backed-up file for each backup session. Further, you should be able to easily restore any of your files up to any given point in time.

Banks do it, big corporations do it, and so should small businesses. Only Remote Backup has such an easy to use version control system. Remote Backup encrypts its backups using your choice of eight of the strongest cryptographic methods in the world for complete security so nobody, not even the RBS Service Provider, can read the files.

Finally and most importantly - Backups are immediately sent offsite and stored safely away from the clients' computers and their businesses. This is where almost every business makes its biggest mistake.

Even if they do everything else perfectly, backups are of little use if their building burns, or they are unable to physically recover their tapes from the premises. Most small companies who do backups leave the tapes in the building with the computer, where they can be destroyed right along with the computer.

Depending on the country you are in, some of these standards may not be available to you. They are all available in the United States and Canada. Your files are encrypted before they leave your system.

Only you have the encryption key. It uses a key length that is variable from four bits to bits. Remote Backup supports three levels of AES from bits to bits.

No Encryption is used in cases where you want to share data among peers, or when the requirements of a particular business do not allow encryption. Remote Backup has many advanced features.

It works with all networks, including Novell Netware and Windows networks.

Developed in the early s at IBM and based on an earlier design by Horst Feistel, the algorithm was submitted to the National Bureau of Standards (NBS) following the.

Data Encryption Standard (DES) is the predecessor, encrypting data in bit blocks using a 56 bit key. Each block is encrypted in isolation, which is a security vulnerability. Triple DES extends the key length of DES by applying three DES operations on each block: an encryption with key 0, a decryption with key 1 and an encryption with key 2.
