Business continuation is very important for internal control. Disaster recovery plan is required to guarantee business continuation. Remote backup is suited for disaster recovery. However, conventional remote backup system has several issues such as communication bottleneck, security, cost and so on. In addition, it must recover the image snapshot taken at any time. In this paper, we propose a backup system which can solve these issues using VLSD (Virtual Large Scale Disks) toolkit. VLSD is a toolkit for constructing large scale disks by gathering free resources. Our system has been developed with VLSD classes. For example, Primary Backup Disk generates differential backup image efficiently. CipherDisk encrypts communication data. RemoteDisk communicate with remote disk server. In a remote side, UnionDisk concatenates differential disk images and then provides accessing to the image of any time.
