The backup script complains about argument of the --folders when backing up the mariadb addon and doesn't create backup

[0101binary0101]

In the backup script.
The mariadb backup doesn't complete correctly on my setup.

time="2021-01-21T23:45:34Z" level=fatal msg="Error while executing rootCmd: flag needs an argument: --folders"

So I commented out the --folders and it works ok

ha addons stop core_mariadb
ha snapshots new --addons core_mariadb --name $(date +"%Y_%m_%d__%H_%M_%S")_core_mariadb # --folders ""
ha addons start core_mariadb

But I've not tried a restore yet.

I've just test and the instruction didn't raised any error:

ha snapshots new --addons core_mariadb --name $(date +"%Y_%m_%d__%H_%M_%S")_core_mariadb --folders ""

Have you some error message and context on your setup ?
The folder option is here to not include any user folders in this snapshot. It's not an issue if you remove it but there is no reason it not works.

OK thank you. Can you share details on your installation and version used ?

[0101binary0101]

Info was on the last screen ... but here's a different way of viewing it. It's 2021.1.15.. I think the folders just can't be an empty string for release.

I can't reproduce on my install:

Could it be other part of the install ?
I'm running Home Assistant OS 5.10. And the shell command is run in SSH & Web Terminal (7.8.0) addon.
I didn't succeed to get the version of the ha cli command.

[0101binary0101]

Looks like a bug to me in the cli since a null value "" almost implies that it's invalid and should be one of the values listed.

root@ha01-pi:/usr/share/hassio/backup# ha snapshot new --addons hassio_cli --name test --folders junk
Error: value must be one of ['addons/local', 'homeassistant', 'media', 'share', 'ssl'] @ data['folders'][0]. Got 'junk'
root@ha01-pi:/usr/share/hassio/backup#

I personally wouldn't have a --folders "" it seems a bit nonsensical , the following shows if you did or didn't include a valid argument.

root@ha01-pi:/usr/share/hassio/backup# ha snapshot new --addons hassio_cli --name test
slug: 8250a216

OK initially I was expecting to have smaller archive with the --folder "". I've just made tests and it changes nothing neither the folders included nor the size.
So OK this is useless and seems source of bug in your context I will remove the option of the script.
