A proven method for effective storage management is archiving technology that frees up storage resources, improves performance, and secures the data that needs to be preserved. The comparison of different technologies for archive storage is complicated by the technology life cycles of the underlying components.
Tape technology is not compatible every 3-4 years (LTO 1 media can not be read by LTO 5), which requires technological updates and complete data migrations. Magnetic hard drives also have a relatively short life, so at least every 4 years, an update of the technology and data migrations are required.
The main problem is that the archive store requires longer retention periods, resulting in data migrations and technological updates to the hard disk and tape. This is associated with high costs and risks that position Blu-ray as a superior file-and-forget archiving technology for a long time.
- Lower costs than theexisting primary storage
Best TCO with low energy consumption and low cooling costs, as well as without data migration and continuous data backup.
- Long-term data retention
Blu-ray media with 50 years and 30 years backward compatibility in non-proprietary data format.
- Compliance with international regulations
Media based on UDF standards provide internal hardware WORM compliance
- Offline administration ofvery old information
With drawable media allows unlimited offline archive storage, allowing system administrators to safely remove data and offload the network.
The total cost of ownership of Blu-ray storages for archival long-term archiving is less than half the cost of traditional alternatives such as hard disk and tape
