When working CRIU uses two directories to keep the data in.
[[Memory changes tracking]] depends on the --prev-images-dir heavily.
== Image directory ==
[[Category:Empty articles]]
This is the one specified with the <code>-D|--images-dir $path</code> option. If not given CRIU uses current working directory. This is where all [[images]] are put.
== Prev images directory ==
When using the [[memory changes tracking]] facility it's important to tell CRIU where images from previous run are. This is done by specifying the path with the <code>--prev-images-dir</code> option.
Remember, that the path given should be ''relative to the images directory'', e.g. like this
<pre>
# criu dump --images-dir ./images-1 --track-mem
# criu dump --images-dir ./images-2/ --prev-images-dir ../images-1 --track-mem
</pre>
Symlinks in paths of absolute paths will not work as well unfortunately.
== Working dir ==
All other files, e.g. [[logging|logs]], [[irmap]] cache, sockets for [[lazy migration|lazy server]] and other go to working dir. By default the working directory is the images directory, but it's possible to override one with the <code>-W|--work-dir $path</code> option.
