SAKURA Cloud is designed to store customers disks and archives in a storage system with high reliability; for example, the system has improved resistance to malfunction through data disk distribution and a redundant hardware structure. Furthermore, SAKURA Cloud is designed so that services are not affected even when localized malfunction occurs. However, we make no guarantee for integrity in the event that a major disaster, etc., damages facilities over a wide area and makes recovery difficult, in the event of an error in the OS or application, or in the event of logical malfunction such as incorrect operation, etc.
Therefore, we recommend that customers use the extensive backup functions available in SAKURA Cloud to periodically back up data themselves.
Disks connected to the server are used for a wide range of task from booting the OS to recording/saving data. Depending on usage, disks may contain personal information, information on business transactions, or extremely important confidential data. In order to guard against the loss of disks and logical malfunctions, SAKURA Cloud provides several ways to easily back up your disks.
One method for backing up disks that have already been created is “disk copy.” This method copies the same contents to another disk. When not quickly connecting to the server for use, another available method is “archive copy.” This enables copying to Archive and inexpensive storing of data. Both of these methods can be used from the [Copy] button on the disk details screen.
This method copies all of the contents of an existing disk to a new disk. Since the copy destination is a disk, it is possible to quickly connect to the server and begin use if a problem occurs with the original disk for back-up.
This method enables storing of an existing disk as Archive. It is not possible to directly connects archives to a server for immediate use; instead, it is necessary to perform write operation to a disk before use. However, this method features inexpensive storage cost that makes it optimal as a storage destination for periodic back-ups.
