%description
ddumbfs is a fast inline deduplication filesystem for Linux based on FUSE
and released under the GNU GPL.
Deduplication is a technique to avoid data duplication on disks and to
increase its virtual capacity.
ddumbfs works at block level. Before to write a block to the filesystem
ddumbfs calculate its SHA1 or TIGER hash and search for it in the
index. If the block already exists the reference is used, if not, the
block is written and the index updated.
It is especially useful to store successive backup, when data are mostly
identical.
ddumbfs is especially efficient with backups of disk images or virtual
machines, when blocks stay aligned on a block boundary.
