Backing Up to Removable Media

According to your backup strategy, certain files or groups of files may take longer than acceptable to complete a backup to tape. In such cases, a good solution may be to back up to disk or other removable media. This backup can take the form of a centralized backup to a large Redundant Array of Independent Disks (RAID) bank, or the archiving of files to DVD or other local devices by individual departments.

When speed and minimal impact is essential, tape and disk backup may be combined. An initial copy is staged to a secondary server’s disk, which is a fast process. A copy of the data then is picked up by a backup program and written to tape. Many backup applications perform the data staging phase as an integral part of the backup.

Backing Up “Into the Cloud”

More and more products are taking advantage of relatively fast bandwidth and inexpensive storage by backing up to remote locations over a wide-area network (WAN). The backup destination may reside at a commercial host’s data center (such as Amazon’s S3 service), or simply over a company virtual private network (VPN) to a remote office.

The term “cloud” came into existence to refer to a service that exists over a network and grants a single interface to its offerings. Cloud services typically offer high scalability on the back end without a subscriber needing to understand the details of how the back end works. With respect to backup, you ship someone your data for storage, which is then available to you on demand. This cloud may be offered by a service provider or by a dedicated group within your company.
