常用示例
Create archive

Extract archive
zpaq extract [archive.zpaq]
List archive contents
zpaq list [archive.zpaq]
Add with maximum compression
zpaq add [archive.zpaq] [files] -method 5
Extract to specific directory
zpaq extract [archive.zpaq] -to [/output/dir]
Incremental backup
zpaq add [backup.zpaq] [directory] -all
说明
zpaq is an archiver with high compression ratios and journaling capability. It uses context mixing and neural network-based prediction for compression, achieving ratios better than most conventional archivers. ZPAQ's journaling feature makes it excellent for incremental backups. Each add creates a new version, and previous versions remain accessible. The -until flag extracts files as they existed at a specific time. Archives are append-only by default - new versions add to the archive without modifying previous data. This provides some protection against corruption and allows versioned backups. Compression levels range from 0 (store only) to 5 (maximum compression, slow).
