*Update 21-Apr-2015: *This script will no longer be supported. Instead please use the new script (for Mac/Linux) available on Github. New article: http://www.talkapex.com/2015/04/apex-backup-script.html
One thing developers like to do is keep local backup copies of their development work. Sometimes they’ll copy files and suffix them with .bak or they’ll store them in a version control repository. With APEX you don’t copy a file to back it up. Either you have to copy the application (within the workspace) or export the application and save it locally. For one-off backups this can be ok, but as you develop with more and more applications in larger environments it can be tedious work and will slow down your development time.
Thankfully APEX has a tool, that comes as part of the install zip file, which allows for command line exports. It’s one of the lesser known tools that is extremely useful.
Below is a simplified copy of a batch file which will automatically backup all the APEX applications on a given database using the APEX backup tool. I usually recommend that organizations run such a script on their development environments to store hourly backups of their development environments. The example is a very simple example which should be modified to tag the backup with the date/time or zip and store the backups in version control. I’ve also appended an extra script which lists all the APEX applications, workspaces, and IDs and stores this information as part of the backup in a .html file.
To use the script, create the files listed below in the same directory and make the appropriate modifications in apex_backup.bat
Backups all the applications in the database
