The On- & Off-site Data Protection feature in Open-E JovianDSS Data Storage Software allows users to back up and restore crucial company data in case of an unexpected disaster due to a combination of several technologies.
This backup-focused feature enables creating consistent snapshots and asynchronous snapshot replication to local and/or remote destinations. The replication tasks can be set according to the specific user requirements thanks to advanced retention plans.
On- and Off-site Data Protection is very flexible, as it covers a wide range of disaster recovery plans without the need to use additional third party tools.
On-site backups are kept at your place of business on the same server with additional internal drives, external drives or on other local Open-E JovianDSS-based servers. Such kind of backup is the most suitable for data protection when a company encounters ransomware attacks, hardware failure, or other disasters. Due to location, data restore is usually easier and faster than in case of an off-site backup. Therefore, it is a perfect solution for hot data which can be restored with minimized downtime or even instantly by switching to the backup copy.
Off-site backups are backed up to a geographically different location. Such backup secures the data in case of e.g. theft, flood, fire, power outages, etc. In case of such disasters, the data can be restored to a new primary location or, in some solutions, the backup can take the primary server's role and the data can be accessed instantly. The data transfer is secured by encryption. This kind of backup is also suitable for archiving purposes. It is also possible to set up several backup locations.
A snapshot is a point-in-time copy of the source volume which can be kept on a local site. It can also be transferred to another location of a volume backup copy. Open-E JovianDSS enables creating an unlimited number of snapshots. Data from a snapshot can be instantly restored with a roll-back functionality or an additional volume (clone).
In the On- & Off-site Data Protection feature, snapshots are asynchronously replicated to local and/or remote locations according to a retention plan that can be customized specifically to individual requirements and the disaster recovery plan. Since snapshots keep only the data that have changed between subsequent snapshots, only the changes are transferred to the destination location as well.
Retention plans are an included feature of the On- & Off-site Data Protection feature that control the automatic creation and deletion of snapshots both on the source and the destination.
They consist of one or multiple rules which are defined by an interval and a retention period. The interval sets how often a snapshot should be taken, and the retention period how long each snapshot should be kept. Each value is described with one of the standard time units: seconds, minutes, hours, days, weeks, months or years.
Any number of rules can be set for a retention plan to adapt it to any backup strategy. Additionally, the plan can be the same for the source and the destination, but it can also be different for both locations.
Now the data is secured with a retention plan consisting of short-, medium- and long-term rules. Any mistakes can easily be undone. The data is secured in case of data corruption or virus attacks, because it can be restored to any state from the last hour, day or month.
