**Title: Trigger Script on LINSTOR Backup Shipping Schedule (Pre/Post Hook Support?)**

Hi all,

I’m using LINSTOR’s **snapshot shipping schedule** feature, and I have a question regarding scripting hooks.

As per the documentation [here](https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-linstor-creating-backup-shipping-schedule), you can create a backup shipping schedule using a command like:

```auto
# linstor schedule create \
  --incremental-cron '* * * * *' \ # (1) Incremental backup cron
  --keep-local 5 \ # (2) Retain 5 local backups
  --keep-remote 4 \ # (3) Retain 4 remote backups
  --on-failure RETRY \ # (4) Retry policy
  --max-retries 10 \ # (5) Max retry attempts
  <schedule_name> \ # (6) Schedule name
  '* * * * *' # (7) Full backup cron schedule

```

followed by

```auto
# linstor backup schedule enable \
  [--node source_node] \ (1)
  [--rg resource_group_name | --rd resource_definition_name] \ (2)
  remote_name \ (3)
  schedule_name (4)

```

I would like to **trigger a script** at two specific points:

1. **Before the shipping starts** – to notify the user that replication is about to begin.
2. **After the shipping completes** – to confirm replication has finished (success or failure).

**Is there a built-in way to have the shipping schedule call a custom script before and/or after the operation runs?**  
Or alternatively, is there a hook/event I can attach to, or a log monitor workaround that is commonly used for this?

Appreciate any insights or examples from those who have implemented something similar.

Thanks!

One option is to disable the linstor schedule and go custom cron.
