A collection of simple tools to copy backup and archive sparse files.

Copies one file to another, preserving sparse blocks and making all-zero blocks sparse.

Cats a file omitting the read of sparse blocks.

Performs a binary diff over two files and produces a difference file with sparse areas.

Applies a sparse patch file from sbdiff to the original file

Produces a data file and a map file of an origial file with sparse blocks.

Merges a map and a data file created with sbmapcat into a sparse file.

Scans a file for all-zero blocks and makes those blocks sparse. Note: This does not work reliably on all filesystems (i.e ext4).

Shows sparse-block and all-zero-block information of files.

Writes stdin to a file, omitting all all-zero blocks.
