3.0.1 backup to remote FTP - constant errors

[banditto9]

The problem

Hello and first of all let me thank you for your kind input with the Auto-backup and RClone add-ons - they helped me to cover the backup task of HA to a remote location.

Unfortunaly, something has broken with the version 3.0.1 when I started receiving constant errors after the task is completed.
It says it can't perform some operations due to IO error. I tried to delete the files on the remote location and in this case it works - it just uploads everying again. Ver 3.0.0 worked just fine for many months without any errors at all. Probably this is a coincidence and now the error appears due to the HA updates - HA get updates almost every 1-2 weeks, but I have no idea how to detect the root cause..

My setup is very simple - there are 2 locations interconnected via WireGuard (latency is around 50ms) and RCclone is configured to upload to a simple FTP which is in the intranet on a second location. FTP runs on the SOHO router and an SSD is connected via USB - using other folders and FileZilla I have no issues uploading/downloading other files so I don't think the SSD is degraded or something like that.

I would be happy to return to ver 3.0.0 but I don't know how to perform add-on downgrade in HA.
Thank you for your time and attention!
