One of the fundamental problems in distributed computing environments is to ensure proper security of user data, which due to the nature of the system, are mostly stored in the dedicated distributed shared disk resources. These resources are available for computing machines (WN) via a special server - Storage Element (SE) with dedicated access protocols such as NFS or LUSTRE. Currently, the numbers of concurrent computing machines exceed a few thousand which, combined with shared disk resources, whose capacity often is counted in Peta Bytes (PB), prevents the efficient archiving (backing up) user data. This can cause the additional load on the SE, while maintaining efficiency in data access. The solution to user data in a distributed shared disk resources is to use the snapshot mechanism (snapshot) which is mostly available in a disk array. The authors present the results of using a dedicated backup system with snapshot mechanism on the disk array with the intermediate backup server and backup software HP DataProtector6.0 for protection of user data in PL-Grid environment.
