If you are now ready to transfer your data to a remote server in the cloud, it is time you had a closer look at how your data will actually be transferred.
The first challenging task associated with data transmission is media restoration. Information stored on disk drives can be easily transferred.
If you have your data stored in tapes, you are in some trouble. Though tape technology is fast becoming a dimension of the cloud and can be seamlessly linked up for backup, the process is as yet in its infancy. The cloud does not, as yet, allow for easy online transfer of data from tapes to the remote server. The data on your tapes may have to be transferred to disks before it can be ported to the remote server. You need to check whether your service provider understands your unique needs and can help you transfer the data from your tapes to the cloud backup server.
However, many cloud backup services offer disk-to-disk-to-tape (D2D2T) backups for data archival and additional backup requirements of enterprises. The cloud backup vendor transfers the data stored in the remote server, back into a tape for shipment to the enterprise for quick archival and local restores. This reduces cost and frees expensive online storage resources for valuable currently active data or ensures that a local store of data is available for instantaneous restores from the tape archives of the organization. A few cloud backup vendors allow users to link up their tape drives to the network and create remote and local backups of information simultaneously using the cloud backup software.
Seeding of information to the cloud is time consuming. If you have to get down to transmitting several thousand terabytes of information from your disk drives over the Internet relying on the available bandwidth, it will consume a lot of resources unproductively. As a result, many cloud backup services permit you to ship your first information “seed” to them on a disk or tape for upload to the cloud backup data server.
Does the data undergo processing changes during transmission to the cloud?
Data uploaded to the cloud backup server is often deduplicated, compressed and encrypted. Encryption algorithms commonly used include AES 256, Triple DES or Blow Fish 448 as these are considered to be standard algorithms and fairly impregnable. Further, files and folders are converted into objects with metadata attached for ease of ediscovery. Data integrity checks and standard protocols may be implemented to ensure standardization of transmission of data from heterogeneous environments.
