What is D2T backup (tape backup)?
Tape backup, also known as D2T (Disk-to-Tape) backup, is a data protection strategy that involves backing up data from a disk to magnetic tape storage media. This method is commonly used for long-term data retention, as tape provides a reliable and cost-effective solution for archiving and storing large volumes of data.
With D2T backup, data is first copied from the primary disk storage to a backup disk array, which acts as an intermediate storage. Then, the data from the backup disk array is transferred to magnetic tapes using tape drives or tape libraries. The tapes are then stored in a secure offsite location, ensuring data redundancy and protection against catastrophic events.
Data protection strategies suitable for long-term retention
When considering data protection strategies for long-term retention, it is essential to implement solutions that address the challenges of data security, scalability, and cost-effectiveness. Here are a few strategies that are suitable for long-term data protection:
1. Tape Backup (D2T)
As mentioned earlier, tape backup is a reliable and cost-effective solution for long-term data retention. Tapes have high storage capacity and can be stored offline, protecting against cyber threats such as ransomware. Additionally, tapes have a long shelf life, making them suitable for archiving data that needs to be retained for an extended period.
2. Cloud Backup
Cloud backup services offer scalable and secure data storage options. By transferring data to a cloud provider’s infrastructure, organizations can benefit from off-site storage and eliminate the need for physical media maintenance. Ensure that the cloud backup provider offers robust encryption, data isolation, and redundancy to meet long-term retention needs.
3. Archive Storage Systems
Archive storage systems are designed specifically for long-term data retention. These systems provide high-density storage and advanced data management features like data deduplication and automated tiering. Data is securely stored and easily accessible when needed. Implementing an archive storage system ensures efficient data retention and retrieval.
4. Data Lifecycle Management
Implementing a data lifecycle management strategy is crucial for long-term data retention. This strategy involves categorizing data based on its value and defining retention policies accordingly. This ensures that data is retained for the required duration and then properly disposed of when it is no longer needed. It helps optimize storage resources and reduces compliance risks.
In conclusion, when considering data protection strategies for long-term retention, a combination of D2T backup (tape backup), cloud backup services, archive storage systems, and data lifecycle management can provide a comprehensive solution. Based on the specific requirements of your organization, choose the most suitable strategy or a combination of strategies to ensure the safety and availability of data over an extended period.
