ON- & OFF-SITE DATA BACKUP
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 instantly restored 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 a 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 recovery 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
With onsite & offsite data protection, snapshots are replicated asynchronously to local and/or remote locations, according to a retention schedule that can be customized specifically to meet individual requirements and 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
Open-E JovianDSS offers dozens of options in terms of high availability environment architecture 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 case of server failure.
