CoreSnapshot Series

This technology uses image data management technology to perform a single backup and restore operation. The SSD capacity is divided into two areas. Before the backup is executed, the data will be written to the two areas simultaneously. Once the backup is executed, one of the areas will be locked as the backup area immediately. Subsequent system operation and data access will be in the user area. When the system encounters problems during operation, the system data can be rescued via remote operation or locally, so that the system can return to normal operation. To perform the next backup, the entire system needs to be reset.

This technology uses the latest incremental data management technology for multiple backup and restore cycles. The SSD capacity is divided into two areas. Before the backup is executed, all system and data will be written to the active area. Once the backup operation is performed, subsequent data will only be written to the incremental area. When the system runs into problems, an admin can trigger a system data rescue via remote operation or locally, so that the system can return to normal operation in seconds. After the restore operation, another quick backup operation can be performed without resetting the entire system.

How Do Backup and Recovery Work?

CoreSnapshot 3, an upgraded version of CoreSnapshot 2, is a new firmware-based instant backup and recovery technology. Unlike CoreSnapshot 2, it utilizes a proprietary algorithm incorporating logical block address (LBA) and tag number within a single user area, eliminating the need to partition the drive into two separate areas. This means that users no longer need to wait for the incremental data area to be erased after a recovery to prepare for a new backup. In simpler terms, CoreSnapshot 3 supports a multi-backup feature that enables users to back up their data whenever necessary.
