Aborted Cloud Sync Tasks does not stop pre-script

I need to backup on daily basis a huge number of small files to google drive

With ordinary cloud sync task it takes over 24 hours (rate limits, small files etc)

I’ve put down a script that uses restic to backup same data with RESTIC_PACK_SIZE=64 to have bigger files.

sync task has config exluding backed up folder content from sync (do not need rclone to do anything)

My scripts is executed as pre-script of sync task and consumes env vars registered by truenas to get source folder and credentials from sync task config

Works fine. But if I abort sync task , my script keeps running .

Tried to ad traps:

# Cleanup function
cleanup() {
    echo "Aborting and cleaning up..." | tee -a "$LOG_FILE"
    pkill -P $$   # Kill all child processes of this script
    exit 1
}

# Trap termination signals
trap cleanup SIGINT SIGTERM SIGHUP SIGKILL SIGQUIT

No luck. Looks like truenas just looses the process of pre-script when task is aborted.
