Remote backup is fast becoming an alternative to traditional backup procedures. Most businesses do not rely on online remote backup as a single source for storage of critical data, but instead use it in addition to traditional backup solutions. It affords them a third storage area and data recovery source in the event of a catastrophic disaster. A remote, online, or managed backup service is a service that provides users with an online system for backing up and storing computer files. Online backup systems are typically built around a client software program that runs on a schedule, usually once a day. This program collects, compresses, encrypts, and transfers the data to the remote backup service provider's servers. A feature of some services is the capability to back up the primary site data plus remote offices and branch offices in a relatively seamless manner. The ability to back up files that are extensively opened, such as Outlook files or SQL database files can be useful. Such ability allows IT administrators to run back up jobs any time of the day, not requiring setting aside server maintenance time. Most online backup products need an add-on for this. A Multi-platform backup service can back up multiple platforms such as the various flavors of Windows, Macintosh, and Linux/UNIX. A continuous backup feature allows the tool to back up continuously or on a predefined schedule. Both methods have advantages and disadvantages. Most backup tools are schedule-based and perform backups at a predetermined time. Some services provide continuous data backups which are used by large financial institutions and large online retailers. However, there is typically a tradeoff with performance and system resources. Some services allow you to access your backed up files via a normal web browser. Many tools do not provide this type of functionality. A way to minimize network traffic is to transfer only the binary data that has changed from one day to the next. The more serious tools use this method rather than transfer entire files. Tools originally designed for network backup use this method.
Remote backup has advantages over traditional backup methods. Remote backup does not require user intervention. The user does not have to change tapes, label CDs or perform other manual steps. It maintains data offsite. Perhaps the most important aspect of backing up is that backups are stored in a different location from the original data. Traditional backup requires manually taking the backup media offsite. Some remote backup services will work continuously, backing up files as they are changed, but most remote backup services will maintain a list of versions of your files. These computer backup systems might have, though, some disadvantages. Depending on the available network bandwidth, the restoration of data can be slow. Because data is stored offsite, the data must be recovered either via the Internet or via tape. Often business might look at data storage in another state as additional protection against data loss, especially if the original area is prone to natural disasters such as hurricanes, tornadoes or earthquakes. Online and remote backup is gaining in popularity for the safety and security of the data. The idea is you download your data through an online process to a remote location that stores the data in a secure environment. Your company has access to the data 24/7 for recovery needs or further backup.
No Backup? Out of Business! Enterprise data backup strategy is a critical issue for any business. Companies are literally forced to employ an enterprise backup policy by legislation, especially if their competence reaches beyond government or medical spheres. It is small to none surprise then that there is a slew of companies in the backup industry hunting for small to mid-size businesses to sell them enterprise backup systems. Setting out on a search for a solid enterprise data backup system inexperienced decision makers will face an overwhelming and ongoing flood of information. NAS-based services, distributed backup, dedupe methods, ROI and optimal backup windows, etc. - all this can confuse even an ultimately decisive person. This is why this responsibility in enterprise environment is usually delegated to a separate backup administration team or there is at least a corporate backup administrator. Companies must take into account many things to maintain continuous 24x7 data protection and set up the best possible enterprise backup method. The most trendy catch phrases in the enterprise backup systems field recently have been "deduplication" and "backup distribution". You are likely to hear more of them as the backup industry develops, so it might be a good idea to get acquainted with these technologies beforehand. Deduplication presupposes economy of disk space capacities by businesses as duplicate data is erased, or rather dealt in a particular way that allows other data to be written to the same spot. There're slight changes in the dedupe methods applied by different enterprise backup systems providers so that they can patent them but in its essence deduplication (or dedupe for short) is all about optimizing the space for backups. Deduplication presupposes that the backup system assigns individual hash values to backed up data and keeps a catalog of all hashes that allows for quick data comparison. There are backup systems that provide ongoing deduplication right in the middle of backing up process or post backup deduplication. Some dedupe systems can also check the data identity by going down to the byte level to eliminate all possibilities of similar hash values and, consequently, data loss. Data distribution is the next most talked about backup topic, and it concerns off-load of the backup server or servers. Enterprise data backup can rarely do without at least several backup servers. It is of outmost importance first of all to lower load for these servers, and second of all to make sure data is backed up all across the network with several nerds. This will provide secure data protection and blitz quick data restore. Even if your enterprise backup methods miss deduplication or distribution techniques, which is a rare case nowadays, you may consider yourself on the safe side. Businesses that have neglected considering and employing a solid backup policy altogether are out of business by now or will be soon. Just google for pitiful Magnolia, JournalSpace, or geek.com, to name just a few.
