Automation Snapshot to NAS for dummies

Configuration
42

Thanks for trying out. Currently you have to create an automation like in hassio-remote-backup. You can find an example in the README.

Thanks a lot for your plugin, Thomas. I’m currently trying to set it up to backup to my Synology NAS. Unfortunately, the transfer always fails with the following error in the log:

Any idea what’s going on there?

Thanks for you work on this: However I’m getting an error.

My Config:

Any ideas?

Hi. Your config looks wrong. As this is linux-based you have to specify the target directory using forward slashes and without a preceding one: “homeassistant/backups”

46

Looks like your Synology and the smbclient are not able to agree on a common SMB version. Which versions does your NAS support?

47

It seems that the Diskstations don‘t accept SMB version 1 connections anymore due to security concerns. It is supposed to work when adding -m SMB2 or -m SMB3 to the smbclient call. Is that possible?

Edit: It seems it was a problem on my Synology side configuration - it was set to SMB1 as minimum and maximum version. Looks better now!

48

Cool! To my knowledge the -m option should not be necessary anymore, as SMB3 is used by default since version 4.7. The current version of the smbclient is 4.11.8

Thanks. That has sorted it.
