REM This script performs a backup of key data in the Docker Compose Alfresco
REM environment that is started using the companion `docker-compose.yml`
REM file.  It backs up the binary data and database.  It ignores the search
REM engine and MQ server.  This is not proper for a production environment.

REM Notice that we are not compressing any of this backup.  We are counting on
REM Git's ability to only deal with differences to get far better effective
REM compression over of the data as it is verioned.  Git also compresses these
REM files in transit and in storage anyway.  By not putting them in ZIP files, we
REM use just as little disk space with one commit and probably 90% smaller over
REM 10 commits and 99% smaller over 100 commits.
