Is this a problem??

[SirGoodenough]

Back-up appears to be working fine, but I spotted something that seems odd.
This is my 'up north' instance, very vanilla no exclusions for the backup, a few exclusions in the rsync.

[05:18:16] INFO: Creating local backup with password.

[05:28:27] INFO: Backup process done!

Notice it still says partial back-up and it lists the things it's ignoring as null. This might be another case of null seeping in from the config.

The config does not mention those 2 excludes, yet it says they are there when the backup happens and are null and a partial backup is the result... (edited)

backup_custom_prefix: SomerHome_backup
backup_friendly_name: true
backup_keep_local: "10"
remote_host: "!secret Eldrad_host"
remote_key: HA_ecdsa
remote_port: 22
remote_user: "off"
rsync_enabled: true
rsync_exclude:
  - /config/*.db-shm
  - /config/*.db-wal
  - /config/*.db
  - "*.tar"
  - keyfile
  - "*.tdm"

  - "*.vmc"
rsync_rootfolder: "!secret EldradB_rsync"
ssh_enabled: true
ssh_remote_directory: "!secret EldradB_path"
backup_password: "!secret EldradB_pass"

Now maybe this is intentional, I don't know. All seems to work. I was just wondering if this is working as intended, or should the absence of config exclude entries mean a complete backup?

In my other instance there are actual excludes...

backup_exclude_folders:
  - media

I'm thinking if neither exclude entry is in config, then a full backup could be done.

Hmm, it seems there is an issue with non-existent config entries, similar to the password issue.
The null shouldn't happen and it didn't on my instance. Can you please post a full log, especially the HA version would be of interest in this case. Thanks!
edit: I think it is a variable type setting issue. We'll need to do a general clean-up of variables and their types. I have not payed too much attention to this type of issue. Sorry, will fix it.

I was able to recreate, the solution as of right now seems to be to switch to bashio::config.has_value as it checks for null, I will try to get an update out within the coming days

[patman15]

@ikifar2012 the

remote-backup-addon/remote-backup/run.sh

Line 109 in b6f76a2

if bashio::var.has_value "${backup_exclude_addons}" || bashio::var.has_value "${backup_exclude_folders}"; then

and similar should not reference the variable but the config entry of course:
if bashio::config.has_value "backup_exclude_addons" || bashio::config.has_value "backup_exclude_folders"; then
or I guess removing the quotes should also work.
