+# Size for the ram folder, it defines the size the log folder will reserve into the RAM.
+# If it's not enough, log2ram will not be able to use ram. Check you /var/log size folder.
+# The default is 40M and is basically enough for a lot of applications.
+# You will need to increase it if you have a server and a lot of log for example.
+SIZE=128M
+
+# This variable can be set to true if you prefer "rsync" rather than "cp".
+# I use the command cp -u and rsync -X, so I don't copy the all folder every time for optimization.
+# You can choose which one you want. Be sure rsync is installed if you use it.

+# If there are some errors with available RAM space, a system mail will be send
+# Change it to false and you will have only a log if there is no place on RAM anymore.

+# Variable for folders to put in RAM. You need to specify the real folder `/path/folder` , the `/path/hdd.folder` will be automatically created. Multiple path can be separeted by `;`. Do not add the final `/` !

+COMP_ALG=lz4
+# LOG_DISK_SIZE is the uncompressed disk size. Note zram uses about 0.1% of the size of the disk when not in use
+# LOG_DISK_SIZE is expected compression ratio of alg chosen multiplied by log SIZE
