By the Numbers: Manila's Digital Archives Are Drowning in Duplicate Images

Manila's public records offices are carrying a measurable dead weight. Across the city's 897 barangays, digitisation drives launched between 2021 and 2024 uploaded an estimated 40 to 60 percent of scanned images as duplicates — meaning roughly two out of every five files stored on city servers right now is a redundant copy of something already on the same system. That figure comes from internal assessments shared at a May 2026 technical briefing of the Manila City Information and Communications Technology Office (MICTS) at City Hall on Padre Burgos Avenue.

The problem is urgent because Manila is mid-way through a broader push to consolidate its civil records under the Philippine Statistics Authority's PhilSys integration program, with a target deadline of December 2026. Redundant image files slow database queries, inflate cloud storage costs, and create version-control headaches when clerks pull documents for official use. With that PSA deadline fixed on the calendar, city IT managers have less than six months to clean house.

What the Files Actually Cost

Storage is not free, and Manila's duplication problem has a peso figure attached to it. The city's current contracted cloud storage through the Department of Information and Communications Technology's (DICT) shared-infrastructure program runs at approximately ₱2.80 per gigabyte per month for government accounts. MICTS estimates the active city records archive at roughly 18 terabytes, of which deduplication audits suggest at least 7 terabytes are redundant image files — duplicate scans of cedulas, barangay clearances, and property documents that were uploaded multiple times during batch-digitisation sprints at offices including the Ermita District Hall and the Tondo Civil Registry satellite station on Delpan Street.

At ₱2.80 per gigabyte, 7,000 gigabytes of unnecessary data costs the city roughly ₱19,600 every month, or close to ₱235,000 a year, purely in storage fees. That number climbs when you add the man-hours clerks spend opening duplicate records in response to document requests at walk-in counters. The Sta. Ana Civil Registry office, one of the busiest in the city, processes an average of 280 document requests per working day. Even a two-minute delay per transaction caused by bloated databases adds up to nearly 10 hours of lost clerk productivity daily, according to figures the office presented to the district's records management committee in March 2026.

The Deduplication Effort Gets Specific

Manila is not approaching this without a plan. MICTS piloted a duplicate-image detection protocol in Sampaloc district starting in January 2026, using open-source perceptual hashing tools to flag files with greater than 95 percent visual similarity. Over six weeks, the pilot cleared 1.3 million image files from the Sampaloc barangay cluster's shared drive, reducing that cluster's storage footprint by 34 percent. The protocol is now scheduled for rollout to Binondo and Quiapo districts before the end of the third quarter.

The Binondo rollout matters particularly because the district's land records — held partly at the Registry of Deeds branch near Ongpin Street — include some of the most duplicated files in the system. Repeated scanning during two separate digitisation grants in 2022 and 2023 left that archive with nearly 210,000 image pairs flagged as likely duplicates. Resolving them requires human review, not just automated deletion, because some near-identical images are legitimately distinct versions of amended documents.

For ordinary Manileños, the cleanup has a practical dimension. Once deduplication is complete, the city's online document request portal — currently limited to Ermita and Malate residents under a 2025 pilot — is supposed to expand citywide. That expansion has been held up in part by the performance drag that bloated databases put on the portal's backend. City officials have pointed to the December 2026 PSA deadline as the forcing function that will either accelerate the cleanup or expose how far behind schedule the work really is. Residents waiting on faster, online access to civil documents should watch the third-quarter Binondo and Quiapo rollout as the clearest test of whether that timeline holds.
