Projects / DIASER


DIASER is a cloud storage class combined geo-data replication, long-term archive system, and WAN vault application. Manage long term mixed data archives generated by existing backup software. Ensure availability using commodity hardware. Retain administrative and financial control. It combines a disk-based backup volume management system and triple redundancy with a storage architecture designed to structure months to years of long term sustainable archiving space. It is a quick and low-cost way to make an environment more robust by backing up data in multiple places. This replication also provides fast retrieval of archived data from all node hosting locations. A Perl installer creates the system. Nodes can be dedicated to storage or used for existing services over unused bandwidth. DIASER works in user space over SSH.
