Here's a confident contrarian opinion: duplicate data (same information stored multiple times) should be retained shorter than unique data, because duplicates multiply risk. Your IPTV panel needs retention by data redundancy (how many copies exist within your systems). An IPTV panel with redundancy-based retention tracks duplicate copies of the same data across databases, caches, and backups—keeping unique data longer (3 years) and duplicate data shorter (delete duplicates after 30 days, keeping only one canonical copy)—turning a uniform retention policy into a deduplication-optimized system that reduces storage and risk. For an IPTV reseller UK, redundancy-based retention is especially valuable because UK resellers often have multiple copies of the same data (main DB, analytics DB, backup, cache)—each copy increases breach risk and storage cost. A real example that reduced storage by 70%: a reseller in London identified duplicate customer records across 5 systems. He kept one canonical copy for 3 years and deleted duplicates after 30 days. Storage costs dropped by 70%, and breach exposure dropped proportionally. The pattern that keeps showing up is that resellers with redundancy-based retention eliminate waste, while resellers without it keep dangerous duplicates forever. What actually works is checking whether your current IPTV reseller panel can: identify duplicate data across systems, designate canonical copies, delete duplicates, and generate redundancy-based retention reports. Most operators find that basic panels have no deduplication tracking, mid-tier panels have manual deduplication (you find duplicates), and great panels have automated deduplication with canonical copy retention. Honestly, the best IPTV reseller UK operators also use "redundancy-based retention review" quarterly—reassessing duplicates because a system that was a duplicate last quarter (testing database) might be canonical this quarter (promoted to production), and the data you deleted too soon is the data you need. Your IPTV panel should keep one copy, because one copy is enough—and enough is all you need.
