backup-subdirectory might not work as expected

[ssaarinen]

Using 'backup-subdirectory' will allow backup to run only once because BackupCommand#buildBackupPath will fail on existing sub directory on consecutive runs. The example using 'nightly' as backup-subdirectory would imply that backup would replace the existing backup every night.

Thanks. Which specific enhancement would you like to see to improve the situation?
One way your desired use case could be solved is something along the lines of:

import java.text.SimpleDateFormat

def date = new Date()
def sdf = new SimpleDateFormat("yyyyMMdd-HHmmss")
def subdirectory = "nightly" + sdf.format(date)

map  = new java.util.HashMap<String, String>()
map.put("configuration", "example")
map.put("backup-subdirectory", subdirectory)
cm = info.magnolia.commands.CommandsManager.getInstance()
cm.executeCommand('simplebackup','backup',map)

Or would you like a flag to delete the contents of an existing directory before taking the backup?

I was going to use the nightly way to make it not consume disk space on old backups since I'm only interested in the latest backup. So to work that way deleting existing content would be ideal. I can just not use the parameter altogether to get history as well.

Also not related but it would be nice if backup process would create dirs instead of complaining that backup directory does not exist :)
