Into the file `/etc/log2ram.conf`, there are three variables : In the file `/etc/log2ram.conf`, there are three variables:
- The first variable define the size the log folder will reserve into the RAM. - `SIZE`: defines the size the log folder will reserve into the RAM.
- The second variable can be set to `true` if you prefer "rsync" than "cp". I use the command `cp -u` and `rsync -X`, I don't copy the all folder every time for optimization. - `USE_RSYNC`: Can be set to `true` if you prefer "rsync" rather than "cp".

- The last varibale disable the error system mail if there are no enought place on RAM (if set on false) - `MAIL`: Disables the error system mail if there is not enough place on RAM (if set to `false`)

The default is to write log into the HardDisk every hour. If you think this is too much, you can make the write every day by moving the cron file : `sudo mv /etc/cron.hourly/log2ram /etc/cron.daily/log2ram`. By default Log2Ram writes to the HardDisk every hour.
