Types of Data Storage Systems
Overview
Every computer and server holds data, but not all qualify as data storage systems. True data storage systems are crucial for recovering files in the event of a disaster. These systems can be located onsite, nearby, or remotely. A wide range of models and media options exists, allowing each system to be tailored to meet a company’s specific requirements.
Models and Media
Data storage systems are predominantly used by medium to large companies. These organizations need reliable storage solutions that facilitate swift file recovery. The choice of storage location often depends on the types of disasters anticipated. For instance, a company in an earthquake-prone area should avoid relying on solely onsite servers and might benefit from remote data solutions.
For example, Wall Street firms maintain mirrored facilities out of state, complete with office essentials and data backups. This strategy ensures minimal downtime, even in the event of a major disaster.
Backup Models
Various backup models enhance the reliability of data storage systems:
- Full Backup with Incrementals: This involves creating a comprehensive backup of all files and storing it securely. Incrementals capture changes at regular intervals. If recovery is needed, the complete backup is restored first, followed by incrementals to update any changes.
- Full Backup with Differentials: This efficient method compares the full backup to current files, copying only the differences. During recovery, only the full backup and the latest differential are needed.
Additionally, some systems connect directly to computer networks to record all activities in real-time.
Media Options
Historically, magnetic tape has dominated data storage media due to its dependability, capacity, and cost-effectiveness. However, modern hard disks are becoming competitive, boasting ease of use and quick data accessibility.
For individual computers, optical discs like CDs and DVDs offer viable storage solutions. Many companies choose to outsource data storage, uploading files via LAN or the Internet for remote storage and recovery.
By carefully choosing the right model and media, companies can ensure their data remains secure and accessible, even in unforeseen circumstances.
