Luc,
When using an SD card as in the Pi we limit writes to the card itself
therefore all logs are to a tmp filesystem or in other words to volatile
RAM. If you do a 'df' command at the Linux prompt you will see what I mean -
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 3762048 1594272 1956956 45% /
devtmpfs 474584 0 474584 0% /dev
tmpfs 479192 0 479192 0% /dev/shm
tmpfs 479192 12344 466848 3% /run
tmpfs 479192 0 479192 0% /sys/fs/cgroup
tmpfs 479192 32 479160 1% /tmp
tmpfs 51200 412 50788 1% /var/log
/dev/mmcblk0p1 102182 19610 82572 20% /boot
tmpfs 95840 0 95840 0% /run/user/0
All of the filesystems defined tmpfs are in RAM. This includes /var/log and
all directories below it.
f you truly want to save data on an ongoing basis I would recommend
installing a USB stick. 32G or more USB sticks are very inexpensive.
You can either specifically mount it in /etc/fstab or make sure that devmon
is running using the following line - This could be the first line in
/etc/rc.local -
# check if devmon is running, if not running, start it
pgrep devmon &> /dev/null || /usr/bin/devmon &> /dev/null
Then direct all things you want to keep to the USB stick.
There are other ways like sending the data to another computer but just
putting it on a USB stick is the easiest. I do this on my hubs storing logs
there and it has worked well. Here is what it looks like in my case in
fstab -
/dev/sda1 59374732 1520772 54814780 3% /media/MS1
I named the stick MS1. It is a 64G stick and after a year of logging has 3%
used!
And yes this could be the same USB stick that you do backups to using
file-backup.sh
