USB Backup - is it possible launch a script before rsync start?

Hi all, first of all thank you for this magic product, OMV is awesome.

One question: I use USB Backup plugin for execute backup of my personal files and docker container files to an external usb drive, and it works very well.

I was wondering if it's possible to launch a script after usb drive is connected and before rsync process is start, and then after usb drive is umounted

This because I would like to pause the containers before the sync start and unpause it after the sync is finished.

Is there a way to realize this?

Some time ago I needed to restore the nextcloudpi docker from usb drive and unfortunately it was in unconsistence state, casued by synced done without pausing/stopping the service.

Thank you very much

Thank very much :), I will try and I hope to succeed!

Thank you again!

Sorry to bother you, and I realize it's not OMV's own topic, but I'm becoming crazy!

I wrote the rule for udev,

ACTION=="add", SUBSYSTEM=="usb", ENV{PRODUCT}=="bc2/aa15/712", RUN=="/script.sh"

the rule works, but whatever script I put in RUN== doesn't work, in syslog I receive "Process '/script.sh' failed with exit code 1.

I tried everything, but i can not understand what I'm wrong

I receive exit code 1 even if in the script I write only #!/bin/bash

Is there any block or customization in Debian 10 or OMV?

Thank you very much!

Yes, same error :(. I tried to call a systemd process, RUN+="/bin/systemctl start --no-block usbbackup.service , from terminal works, but udev same error . I'm going crazy.

Yes, as soon as I have time I try on my ubuntu laptop.

Thank you

Eventually I got workaround through creation of systemd service, that check the presence of device and the starts the script. I don't understand why udev doesn't work, but in the end I achieved my goal.

Thank you very much again

Ciao!
