 <h2>NAME</h2>
 <div class="sectionbody">
 <p>git-repack -
  Pack unpacked objects in a repository
 </p>
 </div>
 </div>
 <h2>SYNOPSIS</h2>
 <div class="sectionbody">
 <p><em>git-repack</em> [-a] [-d] [-f] [-l] [-n] [-q] [--window=N] [--depth=N]</p>
 </div>
 <h2>DESCRIPTION</h2>
 <div class="sectionbody">
 <p>This script is used to combine all objects that do not currently
 reside in a "pack", into a pack. It can also be used to re-organize
 existing packs into a single, more efficient pack.</p>
 <p>A pack is a collection of objects, individually compressed, with
 delta compression applied, stored in a single file, with an
 associated index file.</p>
 <p>Packs are used to reduce the load on mirror systems, backup
 engines, disk storage, etc.</p>
 </div>
 <h2>OPTIONS</h2>
 <div class="sectionbody">
 <dl>
 <dt>
 -a
 </dt>
 <dd>
 <p>
  Instead of incrementally packing the unpacked objects,
  pack everything referenced into a single pack.
  Especially useful when packing a repository that is used
  for private development and there is no need to worry
  about people fetching via dumb protocols from it. Use
  with <em>-d</em>. This will clean up the objects that <tt>git prune</tt>
  leaves behind, but <tt>git fsck --full</tt> shows as
  dangling.
 </p>
 </dd>
 <dt>
 -d
 </dt>
 <dd>
 <p>
  After packing, if the newly created packs make some
  existing packs redundant, remove the redundant packs.
  Also runs <a href="git-prune-packed.html">git-prune-packed(1)</a>.
 </p>
 </dd>
 <dt>
 -l
 </dt>
 <dd>
 <p>
  Pass the <tt>--local</tt> option to <tt>git pack-objects</tt>, see
  <a href="git-pack-objects.html">git-pack-objects(1)</a>.
 </p>
 </dd>
 <dt>
 -f
 </dt>
 <dd>
 <p>
  Pass the <tt>--no-reuse-delta</tt> option to <tt>git pack-objects</tt>, see
  <a href="git-pack-objects.html">git-pack-objects(1)</a>.
 </p>
 </dd>
 <dt>
 -q
 </dt>
 <dd>
 <p>
  Pass the <tt>-q</tt> option to <tt>git pack-objects</tt>, see
  <a href="git-pack-objects.html">git-pack-objects(1)</a>.
 </p>
 </dd>
 <dt>
 -n
 </dt>
 <dd>
 <p>
  Do not update the server information with
  <tt>git update-server-info</tt>.
 </p>
 </dd>
 <dt>
 --window=[N], --depth=[N]
 </dt>
 <dd>
 <p>
  These two options affect how the objects contained in the pack are
  stored using delta compression. The objects are first internally
  sorted by type, size and optionally names and compared against the
  other objects within <tt>--window</tt> to see if using delta compression saves
  space. <tt>--depth</tt> limits the maximum delta depth; making it too deep
  affects the performance on the unpacker side, because delta data needs
  to be applied that many times to get to the necessary object.
  The default value for --window is 10 and --depth is 50.
 </p>
 </dd>
 <dt>
 --window-memory=[N]
 </dt>
 <dd>
 <p>
  This option provides an additional limit on top of <tt>--window</tt>;
  the window size will dynamically scale down so as to not take
  up more than N bytes in memory. This is useful in
  repositories with a mix of large and small objects to not run
  out of memory with a large window, but still be able to take
  advantage of the large window for the smaller objects. The
  size can be suffixed with "k", "m", or "g".
  <tt>--window-memory=0</tt> makes memory usage unlimited, which is the
  default.
 </p>
 </dd>
 <dt>
 --max-pack-size=&lt;n&gt;
 </dt>
 <dd>
 <p>
  Maximum size of each output packfile, expressed in MiB.
  If specified, multiple packfiles may be created.
  The default is unlimited.
 </p>
 </dd>
 </dl>
 </div>
 <h2>Configuration</h2>
 <div class="sectionbody">
 <p>When configuration variable <tt>repack.UseDeltaBaseOffset</tt> is set
 for the repository, the command passes <tt>--delta-base-offset</tt>
 option to <tt>git-pack-objects</tt>; this typically results in slightly
 smaller packs, but the generated packs are incompatible with
 versions of git older than (and including) v1.4.3; do not set
 the variable in a repository that older version of git needs to
 be able to read (this includes repositories from which packs can
 be copied out over http or rsync, and people who obtained packs
 that way can try to use older git with it).</p>
