I have the following code in my bash script to execute xtrabackup from a docker container:  
docker run --rm -it -v /var/lib/docker/volumes/mysql\_mysql\_data/\_data:/var/lib/mysql -v $BACKUP\_DIR:/xtrabackup\_backupfiles perconalab/percona-xtrabackup:8.0.32-26 xtrabackup --backup --no-defaults --compress=lz4 --host=localhost --user=root --password=p0bW9sQxtIhPrqR2 --target-dir=“$BACKUP\_DIR/$MONTHLY\_BACKUP”

I am getting the following output:

So it is failing to create the directory. How should it be? What shall I change? I am not sure is this target dir a relative path to /xtrabackup\_backupfiles when running in docker? I tried different things but could not get it to work.

Hi @Martin_Neumann

> docker run --rm -it -v /var/lib/docker/volumes/mysql\_mysql\_data/\_data:/var/lib/mysql -v $BACKUP\_DIR:/xtrabackup\_backupfiles perconalab/percona-xtrabackup:8.0.32-26 xtrabackup --backup --no-defaults --compress=lz4 --host=localhost --user=root --password=p0bW9sQxtIhPrqR2 --target-dir=“$BACKUP\_DIR/$MONTHLY\_BACKUP”

Here you are mounting your host $BACKUP\_DIR (which I belive points to /root/backup ) into `/xtrabackup_backupfiles` folder inside docker container, however, when you are setting your target dir, you are setting it to `$BACKUP_DIR` which will translate to `/root/backup` inside the container, instead of `/xtrabackup_backupfiles` . Please adjust your backup command to use `--target-dir=“/xtrabackup_backupfiles/$MONTHLY_BACKUP”`
