Hello, I am trying to run a shell script in HassOS (V5.6 64 bits). The shell script is supposed to copy files (HA snapshots) from one directory (/backup) to another directory … When I run the script in SSH, it works perfectly but when I run it in HA (via a shell_command), the directory /backup seems to be empty (???). So I developped another script to have the content (using “ls -al”) of “/”, “/config” and “/backup” (when run within HA, only the last directory is returning an empty list, the other are correct)…
Anyone has a clue why (maybe different containers…) and how to fix this (SSH the script ?) ?
Finally after a lot of research on google, I developped a shell script to copy my snapshots on my Synology NAS (to keep an “offsite” copy) by using two “mount” commands: one mounting the drive on the NAS and the other using Samba to mount a drive on the Raspberry Pi (localhost) to access the backup directory containing the snapshots file (as mentioned before: not available from HA). As RSYNC is not available neither in HA (it is working in SSH though), I added in the script the comparison of the two directories to synchronize them by deleting obsolete snapshots in the target directory, the source directory is manage by the “auto-backup” add-on… The execution of the script is controlled by HA via a shell_command… So done with a lot of work-around’s complicating the script but it is working well… So HassOS is very stable and easy to update/restore but complicating some projects sometimes… Nevertheless I will migrate my two environments from “venv” environment to HassOS…
@baddy-0 Here is the code (by the way this script is submitted from a “ini” script to find a work around to the 60 seconds runtime limit for shell script within home assistant… (see the code at the end):
