`bup midx` creates a multi-index (.midx) file from one or more
git pack index (.idx) files.
-You should run this command
-occasionally to ensure your backups run quickly and without
-requiring too much RAM.
+Note: you should no longer need to run this command by hand.
+It gets run automatically by `bup-save`(1) and similar
+commands.
# OPTIONS
--o, --output
+-o, --output=*filename.midx*
: use the given output filename for the .midx file.
Default is auto-generated.
already exist. This will result in the fastest backup
performance, but may take a long time to run.
+--dir=*packdir*
+: specify the directory containing the .idx/.midx files
+ to work with. The default is $BUP_DIR/objects/pack and
+ $BUP_DIR/indexcache/*.
+
--max-files
: maximum number of .idx files to open at a time. You
can use this if you have an especially small number of file
consecutive objects are often stored in the same pack, so
we can search that one first using an MRU algorithm.)
-With large repositories, you should be sure to run
-`bup midx -a` or `bup midx -f` every now and then so that
-creating backups will remain efficient.
