​XenData Launches File System Mirroring Software

XenData’s new FS Mirror software synchronizes file systems stored in the cloud, local disk, LTO and Sony Optical Disc Archive storage.

The FS Mirror software, costing from $1,800, runs on XenData Hybrid Storage and Archive Servers. The company claims that, “performance is maximized by restoring files from LTO in tape order and from ODA in disc order; File integrity is assured by using end-to-end checksums.”

Dr. 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 synchronized backup mirror copy of one or more file systems and does so in a way that scales to petabytes.”

One use-case for FS Mirror is to synchronize 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 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. 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.

A wide range of robotic LTO libraries are supported including those from Dell EMC, HPE, IBM, Oracle, Overland Storage, Qualstar, Quantum and Spectra Logic. For cloud storage, it supports the hot and cool tiers of Azure Blob Storage.
