Ncp-backup includes data even when IncludeData is set to 'no'

Hello, eveything is in the title :
I would like to backup my nextcloudpi installation but without the data, because I have not a lot of sapce on my ssd (and my files are arleaday saved somewhere else).

I tried with ncp-backup and from nextcloudpi web interface.
The IncludeData option is of course set to ‘no’

Nextcloud version :
Operating system and version : NextCloudPi version v1.36.2
datadir : /var/www/nextcloud/data
backupsdir : /var/www/nextcloud/data/ncp-backups

Also I have found that I have some backups there : /var/www/nextcloud/data/ncp-update-backups but I have no idea what is it (the last backup there is 2 month ago)

The funny thing is that since my backup folder is in the data directory, the older backups are also included in the new one :frowning:

Am I alone in this case ?
Anyone has an idea to solve this ?

Thank you in advance !

I suggest you create a /ncp-backups folder outside the datadir.
If IncludeData is set to ‘no’ only the database and NCdir will be included.
You can set the max number of backups to keep with BACKUPLIMIT

These are created when upgrading NC and have their NC version added to the name.
You can delete them if you dont need them anymore.
