It - can be used to build a simple backup system. One of the unusual - properties of Venti is that duplicate blocks are detected and - coalesced. When <i>vac</i> is used on a file tree that shares data with - an existing archive, the consumption of storage will be approximately - equal to an incremental backup. This reduction in storage consumption - occurs transparently to the user. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - As an optimization, the <tt><font size=+1>−d</font></tt> and <tt><font size=+1>−q</font></tt> options, described below, can - be used to explicitly create an archive relative to an existing - archive. These options do not change the resulting archive generated - by <i>vac</i>, but simply reduce the number of write operations to Venti. - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - The output of <i>vac</i> is the hexadecimal representation of the Sha1 - fingerprint of the root of the archive, in this format:<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>vac:64daefaecc4df4b5cb48a368b361ef56012a4f46<br> - - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - </font></tt> - - </table> - Option to <i>vac</i> are:<br> - <tt><font size=+1>−b</font></tt> <i>blocksize<br> - </i> - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - Specifies the block size that data will be broken into.

This option is useful for building an archive - from a collection of existing archives.
