Package: udevbackup
UdevBackupOn Linux, detects when specified storage devices are connected, then mounts them,
executes a script, unmounts them and tells when it is done (using mail or text to speech).A config file defines storage devices and the scripts to run.I wrote this script for a simple offline backup of my server: I just have to turn
the external USB drive on and wait for the message (using text to speech) before
turning it off again. UdevBackup double forks before running the script, so
there is no timeout problem with udev and slow scripts.Require the "at" utility for running long jobs (more than 30 seconds).installationsudo pip3 install udevbackup --upgradeyou need to create a udev rule to launch udevbackup when a new device (with a file system) is connected:echo 'ACTION=="add", ENV{DEVTYPE}=="partition", RUN+="/usr/local/bin/udevbackup at"' | sudo tee /etc/udev/rules.d/udevbackup.rules
udevadm control --reload-rulesIf you only have short jobs, you can useecho 'ACTION=="add", ENV{DEVTYPE}=="partition", RUN+="/usr/local/bin/udevbackup run"' | sudo tee /etc/udev/rules.d/udevbackup.rules
udevadm control --reload-rulesconfigurationCreate a .ini config file with a "main" section for global options, and another section for each
target partition. The name is not important. All .ini files in /etc/udevbackup are read.
These files must use the UTF-8 encoding.You can display all available options with the "help" command, but .udevbackup help

Create one or more .ini files in /etc/udevbackup.
Yellow lines are mandatory.
