Maintain NALCOMIS-OIMA, NALCOMIS-OOMA, and NALCOMIS-ERP interface functionality

Backups, recovery, and continuity

Execute daily, weekly, monthly, and annual backups using Veeam Backup and Replication
Verify backup integrity, maintain off-site copies on external storage, and execute system recovery procedures

Diagnose and resolve remote desktop, connectivity, interface, account, application, and database issues
Submit trouble reports and change proposals through the applicable Navy ITSM system and to NIWC Norfolk
Support squadron OOMA administrators with deployment preparation, Homeguard virtual machine upload and download, detachment system setup, and NGEN/NMCI reconnection
