 #### What is getting backed up by AIO's backup solution?
-Backed up will get all important data of your Nextcloud AIO instance like the database, your files and configuration files of the mastercontainer and else. Files and folders that are mounted into Nextcloud using the external storage app are not getting backed up. There is currently no way to exclude the data directory because it would require hacks like running files:scan and would make the backup solution much more unreliable (since the database and your files/folders need to stay in sync). If you still don't want your datadirectory to be backed up, see https://github.com/nextcloud/all-in-one#how-to-enable-automatic-updates-without-creating-a-backup-beforehand for options (there is a hint what needs to be backed up in which order).

 #### How to adjust borgs retention policy?
 The built-in borg-based backup solution has by default a retention policy of `--keep-within=7d --keep-weekly=4 --keep-monthly=6`. See https://borgbackup.readthedocs.io/en/stable/usage/prune.html for what these values mean. You can adjust the retention policy by providing `--env BORG_RETENTION_POLICY="--keep-within=7d --keep-weekly=4 --keep-monthly=6"` to the docker run command of the mastercontainer (but before the last line `nextcloud/all-in-one:latest`! If it was started already, you will need to stop the mastercontainer, remove it (no data will be lost) and recreate it using the docker run command that you initially used) and customize the value to your fitting. ⚠️ Please make sure that this value is valid, otherwise backup pruning will bug out!
