DeduplicationStrategien
Deduplication is a data reduction technique that eliminates duplicate copies of repeating data to reduce storage capacity and bandwidth usage. It operates by identifying only one copy of identical data and replacing duplicates with references to that copy, which allows systems to store or transmit fewer bytes while preserving data integrity. Deduplication is commonly used in backup and archive systems, primary storage arrays, and cloud storage, where large volumes of similar data are created and retained.
There are several approaches. File-level deduplication compares whole files and stores a single instance of identical
Benefits include reduced storage footprint and lower network bandwidth for backups, with potential cost savings. Limitations
