Hi,
in order to backing up data when I connect to computer an USB HD, I wrote
the follow UDEV rule :
------------------------------------------------------------------
SUBSYSTEM=="block", ACTION=="add", ATTRS{vendor}=="152d",
ATTRS{model}=="0578", SYMLINK+="external%n",
RUN+="/usr/bin/mrs-auto_backup.sh"
-------------------------------------------------------------------
the rule is the content of the file :*
/etc/udev/rules.d/10.autobackup.rules *
that I self created .
I learned this method at the link :
https://www.tecmint.com/auto-backup-files-to-usb-media-in-linux/ *("How to
backup files to USB media when connected*")
As well I tried in many different combinations and parameters values, never
I was able to execute the script inside the rule.
-----
In order to get the USB HD characteristic of the USB Hard Disk to use for
backing-up the data I used the command :
*<sudo udevadm info -q all -n /dev/sdc>*
and its output is transcribed below
Could someone help me to understand because this rule doesn't works ?
thank you
regards
Angelo
