Samba Backup: Create and store backups on a Samba share

tomg1970 · December 17, 2021, 10:17am

Hello I have some problem to get the addon to work. I always get an error message. That the permissions are not correct. I do not know what else to look on the synology.
Where exactly can I find the correct data on the Synology NAS.

  host: 192.168.x.x
  share: NAS
  target_dir: backupha

First: You don’t have to “x” you local IP addresses. Nobody can reach them!

What you have written above as configuration, can not be the reason for this error!
I think you have this configuration:

  host: //192.168.x.x
  share: NAS
  target_dir: /backupha

You see the “//” and the “/” in front of the host and the target_dir? These are written in the error, so they are in your config. Simply delete them, and it should work, if you have a share named “NAS” and a folder inside this share named “backupha” on the server 192.168.x.x.

@thomasmauerer thank you for this add on! Works great, excellent job!

Guys, has anyone figured out how to create an automation so that every time I manually create a snapshot (ie, full/partial snapshot, like before updating etc) it gets sent to the smb share configured in the addon?

Will you develop this tool more? Will be nice to have a “stop addon” before backup.
Google Backup do this, to prevent database failure when restore MariaDB.

This error: “NT_STATUS_LOGON_FAILURE” looks totally different than before: “NT_STATUS_NOT_FOUND”. So it seems you have changed your config in the meantime.
The error you now have tells me that you have used false credentials to log on. There is no “backupuser” with the password defined. You should check this!

[21-12-20 08:48:04] FATAL: Cannot access share. It seems that your configured share does not exist.
[21-12-20 08:48:05] FATAL: I found the following shares on your host. Did you mean one of those?

Are you really know what you have to set for the different options?
For the option “share:” you have to set a share from your server! You got a list of shares of your server in the error message. What should this tell you?
You don’t have a share named “NAS” on your server!
You have so many shares on your server, that I think you should know what you are doing there and what the meaning of “share” and “folder” is.

So why do you set “NAS” as a name for a share?

And I think that there is no folder named “backupha” on your share, that you want to reach!

These are the first things I asked you:

So correct these things and it should work!

pepe59 · December 20, 2021, 9:27am

What is the share name on your NAS device? What folder name where do you want to save the backup to the NAS device? What username did you enter to access the shared folder on the NAS device? What password did you enter to access the shared folder on the NAS device?
This is the data you enter in the add-on!

tomg1970 · December 20, 2021, 9:56am

Thank you for the feedback.
No, I am not sure what exactly has to be entered where and in what form.
This is my Synology Folder:

This is my SMB Config

This are my backup user:

thomasmauerer · December 20, 2021, 10:34am

Your config should look like this:

host: 192.168.1.43
share: backupha
target_dir: ''

And the user haadmin must be granted write permissions.

carsten_h · December 20, 2021, 11:55am

That looks like “backupha” is your share.
So the config that @thomasmauerer posted should be correct.

Viel Erfolg!

tomg1970 · December 20, 2021, 12:24pm

Thank you very much it works…
Is there also a possibility to backup several times a day and delete an old backup after 8 days?

carsten_h · December 20, 2021, 12:58pm

Not direct in the configuration. You can manually trigger Samba backup from an Home Assistant automation. This is described in the last part of the documentation under “Manual Triggers”.

The deletion will take place after x backups not after x days. Maybe an automation works here also.

tomg1970 · December 20, 2021, 3:43pm

Thanks Carsten.
So I’m sure I’ll get several backups. But how I delete with an Automtion zb after 8 backup, the oldest, there I am then unfortunately over questioned

carsten_h · December 20, 2021, 7:29pm

I can also not tell you (Ich bin da echt überfragt!). Maybe someone else here has an idea how to handle it.

tomg1970 · December 21, 2021, 6:16am

Hihi Ok verstehe Dich Thanks

e-raser · December 28, 2021, 1:46am

@thomasmauerer have you thought about providing an additional whitelist approach by offering two options include_addons and include_folders?

During this Correct "wait until finished" syntax (e. g. 'wait_for_trigger') - #5 by e-raser question:

Is it possible to manually trigger Samba Backup addon so it creates only a HA backup?

…I was wondering why there´s no such “feature” yet. Currently it’s quite a pain to have SAMBA backup create a partial backup only containing HA + HA config folder because I need to exclude everything else. So I need to maintain a list of things I don’t want (and that list is constantly changing which adds the need to update my exclusion list also) to get what I want. Strange, isn’t it

Curious to see if this is something you thought about or what you think of it.

Danny2100 · December 29, 2021, 10:06am

I’m struggling to exclude influx db from backups.

Influx db’s url is a0d7b954-influxdb and I took the url from the same place for mariadb and it worked but not for influxdb.

exclude_addons:
  - core-mariadb
  - a0d7b954-influxdb
exclude_folders: []

@thomasmauerer any ideas? I also tried using _ instead of -

Vahaldor · January 16, 2022, 7:21pm

I am receiving error despite the fact the addon is apparently connected to my samba. Any ideas?
