Your account has a Postgres service and an n8n service in the "robust-passion" project, plus a "Hermes Agent" service. Could you clarify which service lost data and what you mean by "upgrade" (e.g., upgrading n8n version, upgrading Postgres, or upgrading your Railway plan)? If data was stored on the ephemeral filesystem rather than in a volume or database, it is not recoverable after a redeploy. If your Postgres service has a volume with backups configured, you can restore from a backup in the service's Backups tab, as described in our backups documentation.

Hermes Agent

Hermes Agent, under /root/trading folder, i found that my scripts are lost

anyone can help?

not resolved ..

Did you have a volume attached to the service?

yes, please give a help

can you copy my previous data from /root/trading folder to /data/trading folder?

IIRC if your application stored data in the / directory, that would not be stored in the volume, since volumes can't be mounted at /.

Did your application save data in /?

my data was under /root/trading

Is your volume currently mounted at /data or /root?

seems /data now after plan upgrade, can help me to copy /root/trading to /data/trading?

Can you double check the current mount path by clicking into the volume then going into its settings?

yes /data

Change it to /root and save the changes.

Redeploy your service after.

but i found some data are still in /data

If your volume was mounted under /data and you tried saving data into /root, the data would not be stored in the volume, and would be unrecoverable if lost.

oh my god, any alternative?

As I mentioned above, data stored in ephemeral paths are not recoverable once lost.

how come upgrade plan become loss data ...

may i know how to export the file from /data folder?

coz i have concern to continue to use railway service and want to export file under /data folder, please give me a standard procedure for download file, many thx for your help

Upgrading plans would not affect how the volume was mounted. If you lost data, it was most likely stored in an ephemeral path and redeployed at some point, and thus, cannot be recovered.

yes, understand, i just want to export file under /data folder now, please give me a standard procedure for download file, many thx for your help

tbh, the user experience is not quite good

As mentioned above, you can deploy a Filebrowser instance, unmount your volume from your service (make sure to remove all deployments before this step), and mount the volume to Filebrowser. You should be able to download the files from there. Make sure to add the variable USE_VOLUME_ROOT=1 to the Filebrowser service.

please share the step by step guideline

The steps are written above...

seems u can't help me, can you pass the case to your manager?

coz i would like to backup data and waive the upgrade plan fee

anyone can help on this request
