Open-E JovianDSS offers unlimited possibilities for architecting storage environments with iSCSI, Fibre Channel (FC) and NFS, SMB (CIFS) protocols for companies of all sizes - from small family businesses to mid-sized and large enterprises. With its Linux-based architecture, Open-E JovianDSS offers significantly better hardware compatibility than competing products based on other operating systems. Open-E JovianDSS is a perfect choice for any virtualized storage environment as it supports VMware, Citrix and Microsoft Hyper-V. It can be deployed on physical servers or as a virtual storage appliance (e.g. in hyper-converged environments).

ON- & OFF-SITE DATA BACKUP

The On- & Off-site Data Protection feature in Open-E JovianDSS Data Storage Software enables users to backup and restore critical enterprise data in the event of an unexpected disaster using a combination of technologies.

This backup-focused feature enables the creation of consistent snapshots and asynchronous snapshot replication to local and/or remote destinations. Replication tasks can be set according to specific user requirements thanks to advanced retention schedules.

On- and offsite data protection is very flexible, covering a wide range of disaster recovery plans without the need to use additional third-party tools.

On-site (local) backups

On-site backups are kept in your organization on the same server with additional internal drives, external drives, or on other local Open-E JovianDSS-based servers. This type of backup is best for data protection when an organization is affected by ransomware attacks, hardware failures, or other disasters. Because of its location, restoring data is usually easier and faster than in the case of an off-site backup. Therefore, it is a perfect solution for hot data that can be restored with minimal downtime or even instantly by switching to the backup copy.

OFF-SITE (REMOTE) BACKUPS

Offsite backups are backed up to a geographically different location. Such backup secures the data in case of e.g. theft, flood, fire, power failure, etc. In case of such disasters, the data can be restored to a new primary location or, in some solutions, the backup can take over the role of the primary server and the data can be retrieved immediately. Data transfer is secured by encryption. This type of backup is also suitable for archiving purposes. It is also possible to set up multiple backup locations.

DATA RECOVERY

Instant recovery from the same server. Important or "hot" data can be restored instantly from one or more snapshots using the snapshot rollback feature. Users can also access snapshot data and manually restore any selected files.
Data recovery from a local backup server. With a local backup server, data is available in the same location and can be restored with a minimum of downtime by temporarily using a backup server as the data server while the primary server is restored.
Data recovery from off-site locations. It is possible to immediately switch to the backup server and temporarily use it as the primary location (depending on the system structure) and perform the restore in the background. Restoring data from an external server can be more time-consuming, depending on the amount of data to be restored as well as the connection throughput.

CONSISTENT SNAPSHOTS

A snapshot is a point-in-time copy of the source volume that can be kept in a local location. It can also be transferred to another location of a volume backup copy. Open-E JovianDSS allows you to create an unlimited number of snapshots. Data from a snapshot can be restored instantly with roll-back functionality or an additional volume (clone).

With onsite & offsite data protection, snapshots are replicated asynchronously to local and/or remote sites according to a retention schedule that can be customized specifically to meet individual requirements and the disaster recovery plan. Since snapshots retain only the data that has changed between successive snapshots, only the changes are transferred to the target location.

BUSINESS CONTINUITY

Continuous availability of all data keeps the business running and allows companies to maintain all operations, even when critical situations or disasters occur. This is achieved with high availability systems that aim to provide a data storage user with the highest possible performance, reliability, availability, redundancy and efficiency by minimizing downtime and eliminating single points of failure.

Open-E JovianDSS offers dozens of options related to the architecture of high availability environments with iSCSI, Fibre Channel (FC) and NFS, SMB (CIFS) client protocols. With these options, you can set up high-availability storage clusters with load balancing that ensures reliability and redundancy through failover in the event of a server failure.
