Easy Data Movement with QuantaStor SDS Using Backup Policies and Automated Storage Tiering -- Scheduled movement of data between appliances in a storage grid improves efficiency and facilitates recoverability, when needed.
Backup Policies are a feature of the OSNEXUS QuantaStor SDS platform allowing IT administrators to set up data backups that run automatically on user-specified schedules. They ensure data recoverability for scenarios including accidental application downtime, hardware failures, and business disruptions caused by computer viruses or hackers. The OSNEXUS QuantaStor SDS (Software Defined Storage) platform delivers a complete array of enterprise features and capabilities for file, block, and object storage.

What are the benefits of Backup Policies?

An important benefit of using the Backup Policy system is its automatic generation of snapshots. This enables users to recover lost files from previous versions on their own without having to engage IT staff to restore data from tapes. The number of retained snapshots is configurable to meet recovery time objectives and SLAs. Long-term retention rules for snapshots enable IT Administrators to rotate daily, weekly, monthly, and quarterly snapshots which are space-efficient and help to protect organizations against viruses and ransomware. QuantaStor's Backup Policy system is heavily parallelized and can scan very large file systems with hundreds of millions of files to make better use of network bandwidth. With Automated Storage Tiering, data can be moved as well as copied, and, users can choose files based on specified file age ranges.

What is Automated Storage Tiering?

Automated Storage Tiering lets IT Administrators easily set up the scheduled movement of data between appliances in a storage grid through new enhancements to QuantaStor's Backup Policy engine in version 4.5. This is useful for automatic migration of data from expensive all-flash pools of storage to lower-cost storage pools based on file age. With QuantaStor's storage grid technology, the movement of files can be done from any QuantaStor appliance to any other appliance within the storage grid, or to 3rd-party NAS filers, and even into cloud-based S3 storage.

Which industries most need Automated Storage Tiering?

In the Media & Entertainment industry, post-production studios have high performance requirements on active projects and lower performance requirements after projects are completed and are ready to be archived. Similarly, research and development fields like Life Sciences also have the need for automatic movement of files to archive tiers, to ensure maximum availability of scarce high-performance computing storage resources. Automated Storage Tiering can be setup by IT Administrators in minutes through QuantaStor's web interface or done via scripts and REST APIs that are set to run automatically on a schedule, thereby eliminating the ongoing labor costs associated with data migration.

Which servers or appliances can be backed up?

Backup Policies can be used to backup data to or from Windows servers, Linux-based servers, and 3rd-party NAS filers including NetApp, EMC Isilon, EMC VNX, and S3-compatible object storage when combined with QuantaStor Cloud Containers. Because they can be used to backup data to or from any NFS or SMB accessible folders on the network, Backup Policies are highly versatile.

How quickly can data be backed up with Automated Storage Tiering?

QuantaStor SDS utilizes a parallelized backup engine that can copy or move files as specified by policy while retaining extended attributes and permissions. The parallelized backup engine is able to rapidly scan massive file systems to identify newly created or changed files using upwards of 64 concurrent streams. This makes it an ideal solution for backing up large scale-out NAS filers and now for automatic migration of older data to or from scale-out NAS filers.
