The evolution from traditional archive to archive to cloud
Interest in data archiving has increased over the past few years. Data archiving has evolved into a cloud-based archiving solution due to the explosive growth of corporate data and the need to keep it for longer periods of time in order to meet certain regulatory requirements.
Archive, unlike backup, is to put the inactive data from main storage to another easy to access, also cheaper on a secondary storage layer, and then delete it on a local disk resource. This reduces costs by freeing up more expensive primary storage, reduces backup Windows, increases operational efficiency, and provides long-term data protection reliability. A viable, efficient data archive should provide: scalability, cost-effectiveness, availability, and long-term data protection
In this article, we'll take a closer look at the evolution of the data archiving process and the different data archiving methods, which are:
1. Traditional Archive
This backup archive is a traditional tape-based archive. As part of the backup process, a backup software or system device is applied to write data to tape or an automatic tape library, and the data is saved from disk to tape. These tapes and the data they contain are separated by regular backups and specified for a longer retention period, usually from 10 years to unlimited length. When the data backup is removed from the server's disk drive, these archive tapes are sent to a remote storage device for permanent storage.
The advantages of this approach are that tapes are relatively inexpensive, easy to manage, last a long time, and provide very reliable storage for large amounts of data that can be stored very efficiently.
The disadvantages of tape are that you have to wait for the tape to be fetched from another location before you can retrieve it, and then it takes time to scan the tape, find the data to be recovered, and recreate the tape to store the data.
2. Disk-based Data Archive
Along with the globalization, and the disintegration of the traditional corporate structure, no longer as before, there is one or two central locations, now the company has several offices, scattered in different areas, need to be quick and easy to get a lot of documents, research, and other business cooperation thus was born the Disk-based Data Archive.
These systems provide fast, easy-to-manage storage, easily scalable incapacity, and the necessary tools and software to manage the archive process. These systems also provide data protection characteristics beyond RAID6, data retention, data validation integrity, and WORM(multiple access once wrote) capabilities.
The benefits of this archiving approach are that copies of the data can be stored online and accessed easily and quickly.
The downside to disk-based archiving for the enterprise is that the enterprise has to buy approximately 50 terabytes of disks at the beginning of the purchase. For many businesses, it is neither practical nor cost-effective, and they buy so much disk space that they may only need 1 or 2 terabytes initially.
3.Archive To Cloud
Since with shrinking budgets, shrinking payrolls, and growing demand for data storage, companies are looking for other, more cost-effective ways to expand their storage capacity. Now, enterprises are looking at the latest developments such as cloud computing, storage as a Service (SaaS) as a possible way to meet their requirement of the growing storage while meeting the requirement of reducing costs, personnel, hardware, architecture, etc.
Service providers in the territory of cloud storage offer almost infinite scalable storage to the enterprise, which is a fixed cost on an application basis. This allows enterprises to expand their storage on a need-based basis without having to worry about the usual costs, usually extending the disk environment, such as creating more architectures, hiring, training more people to manage additional storage, increasing the cost of refrigeration, electricity, and so on for additional storage. For other advantages, this service model also provides a geographically multi-site architecture. It allows multi-site businesses in different regions to access their data from the network at any point in time. All this access is transparently provided to users and presenters. These solutions often apply enterprise existing architectures and applications easily when providing secure connections to all data transfers.
Because of improved data archive access and reliability, users are more inclined to move data from primary storage. This would not only reduce the cost of the primary storage, and reduce the cost of data protection and disaster recovery.
Meanwhile, Vinchin Backup & Recovery also will add the new feature - Archive Backup To Cloud which supports AWS and AlibabaCloud, on the upcoming Version 6.0. That means you can archives the backup data again to local storage or cloud storage for secondary backup by Vinchin Backup & Recovery to realize the data protection.
