bup-bloom(1) General Commands Manual bup-bloom(1) NAME bup-bloom - generates, regenerates, updates bloom filters SYNOPSIS bup bloom [-d dir] [-o outfile] [-k hashes] [-c idxfile] [-f] [--ruin] DESCRIPTION bup bloom builds a bloom filter file for a bup repository. If one al- ready exists, it checks the filter and updates or regenerates it as needed. OPTIONS --ruin destroy bloom filters by setting the whole bitmask to zeros. you really want to know what you are doing if run this and you want to delete the resulting bloom when you are done with it. -f, --force don't update the existing bloom file; generate a new one from scratch. -d, --dir=directory the directory, containing .idx files, to process. Defaults to $BUP_DIR/objects/pack -o, --outfile=outfile the file to write the bloom filter to. defaults to $dir/bup.bloom -k, --hashes=hashes number of hash functions to use only 4 and 5 are valid. de- faults to 5 for repositories < 2 TiB, or 4 otherwise. See com- ments in git.py for more on this value. -c, --check=idxfile checks the bloom file (counterintuitively outfile) against the specified .idx file, first checks that the bloom filter is claiming to contain the .idx, then checks that it does actually contain all of the objects in the .idx. Does not write anything and ignores the -k option. BUP Part of the bup(1) suite. AUTHORS Brandon Low <lostlogic@lostlogicx.com> Bup 0.32 2021-01-09 bup-bloom(1)
