Case Study: Denver Public Library achieves 84% shorter backup window with ExaGrid

Denver Public Library Cuts Backup Window by 84% with ExaGrid System

Denver Public Library, which serves over 250,000 patrons through 27 branches, was struggling with tape-based backups that exceeded its backup window and ate up staff time—full backups stretched across the weekend (previously up to 48 hours) and administrators spent 4–6 hours weekly managing tapes and restores.

The library deployed an ExaGrid disk-based backup system (primary plus a replicated DR appliance) that integrates with Symantec NetBackup; backups now complete in eight hours (an 84% reduction), weekly backup management falls to about 30 minutes (≈90% less time), deduplication reaches up to 28:1, and retention increased from one month to six months—delivering affordable scalability and improved disaster recovery.
