XenData launches file system mirroring software


XenData, a global provider of high capacity data storage solutions, launches FS Mirror software which syncs file-folder structures between cloud, local disk, LTO and Sony Optical Disc Archive (ODA) storage. The software is optimised in terms of performance and integrity specifically for these storage types: Performance is maximised by restoring files from LTO in tape order and from ODA in disc order; File integrity is assured by using end-to-end checksums.

An attractive use-case for FS Mirror is to synchronise a file-folder structure held on an LTO archive, an ODA system or on shared disk storage to a clone copy stored in the cloud. In addition to providing a data protection copy in a cloud location, it supports multi-site access to the entire cloned file system.

Another mode of use is to replicate the file-folder structure on shared disk storage to LTO data tape cartridges within a robotic library. FS Mirror provides a cost-effective data protection solution for high capacity disk volumes that scales easily to multiple petabytes. And, if a file is accidentally overwritten or deleted on the shared disk storage, old and deleted versions of any file can be restored individually from LTO. In the case of a serious problem with the shared disk storage, the complete file system can be easily rebuilt from LTO using the FS Mirror software which will rapidly recover files in tape order.

The FS Mirror software runs on XenData Hybrid Storage and Archive Servers. A wide range of robotic LTO libraries are supported including from Dell, HPE, IBM, Oracle, Overland Storage, Qualstar, Quantum and Spectra Logic. For cloud storage, it supports the hot and cool tiers of Azure Blob Storage.

Phil Storey, XenData CEO, commented, “Conventional backup software does not scale to very large volumes of digital assets because there is never enough time for a full backup and restoring from hundreds or thousands of incremental backups is unreliable. FS Mirror provides a synchronised backup mirror copy of one or more file systems and does so in a way that scales to petabytes.”
