--dedup xtool directly addresses these failures. By allowing an external tool, the user can deploy a content-defined chunking algorithm (like FastCDC) that resists boundary shifts. For images, the external tool could be a perceptual hash function (e.g., phash ). For cryptographic integrity, the external tool could be b3sum (BLAKE3). The command becomes a pluggable architecture for truth.
Which game or software are you compressing? What is your total system RAM ? Are you using internal codecs or external plugins ? --dedup xtool
: Sets the memory limit (in MB) for the deduplication database. --dedup xtool directly addresses these failures
Under the hood, the following steps occur: For cryptographic integrity, the external tool could be
Newer versions use to prevent crashes when processing massive files that exceed physical RAM. 2. Hashing and Collisions Older versions used CRC32C .
Run XTool with a smaller minimum chunk size to maximize space savings (at the cost of speed):
