Backup docker named volume

# Here's how to back up a named volume

# 1. Using a `ubuntu` image, we mount the named volume (`myproj_dbdata`) to a `/dbdata` folder inside the `ubuntu` container.
# 2. Then, we create a new folder inside the `ubuntu` container named `/backup`.
# 3. We then create an archive containing the contents of the `/dbdata` folder and we store it inside the `/backup` folder (inside the container).
# 4. We also mount the `/backup` folder from the container to the docker host (your local machine) in a folder named `/backups` inside the current directory.
docker run --rm -v myproj_dbdata:/dbdata -v $(pwd)/backups:/backup ubuntu tar cvf /backup/db_data_"$(date '+%y-%m-%d')".tar /dbdata

Thanks! This is really helpful!

can you please explain this for windows

Becareful to don't backup the database files while the database process is up and running, you could backup a corrupted database.

Another way would be to dump the db with the appropriate tool, then backup the dump.
