/jffs/.asdbk/main_checker.sh_bk growing

[altium]

Hi,

I'm running 3004.388.6 and I have a custom backup script stored in /jffs/scripts.

The main part of my script:

# Saving NVRAM
echo "Saving NVRAM..."
nvram save /tmp/"$nvram_backup".cfg
nvram show > /tmp/"$nvram_backup".txt

# jffs tar
echo "Saving /jffs..."
tar -cf /tmp/$jffs_file -C /jffs .
if [ $? -ne 0 ]; then
 echo "Error. Exiting..."
 exit 1
fi

# tar.gz
echo "Creating archive..."
tar -czf /tmp/$archive_file -C /tmp $nvram_backup.cfg $nvram_backup.txt $jffs_file
if [ $? -ne 0 ]; then
 echo "Error. Exiting..."
 exit 1
fi

After this I'm uploading the tar.gz with curl.

I have noticed that the output tar.gz is constantly growing. After some investigation I've realized that the file /jffs/.asdbk/main_checker.sh_bk was at the end 90MB...

Does somebody have an idea what is the purpose of this file and why is it growing? How can I avoid this?

Thanks in advance!

It’s usually a copy of the last file that the ASD security daemon checked or auto-deleted. See what’s in it. Mine was a Adblock blocklist, for example.

There is a lot of binary like part, some outputs (eg. hostapd, wlceventd, dnsmasq-dhcp), the source of all of my scripts stored in /jffs, curl output and so on. Looks like a mixture for me.

Maybe it’s a copy of your tar backup?

That seems to be a logical answer, thanks ! Question is then, how can I avoid it to grow? Should I simply exclude it from the tar or there is some smarter way to achieve my goal?

You could use a tar exclusion file, or take a look at BACKUPMON, which essentially does much of what your script does, but also includes a copy of your External USB drive as well... and it makes use of exclusion files.
