Regarding the second question, the answer is yes, but not as you might think. The backup will start and when the step finishes, it will "hibernate" until the next visitor stops by. It will also run if anyone logs into the back-end. However, due to the very low traffic, you can't hope for daily backups. At the very best you'd get one backup every 2-3 days. In fact, if you have such a low traffic site, there is absolutely no point in setting up a daily backup ;)
Regarding the other issue, as the message reads, you are not entering the correct FTP initial directory. In order to figure out the initial FTP directory of your remote server you have to do the following. Connect to your remote FTP site with an FTP application, e.g. FileZilla. Navigate into the directory where you wish to place the backups. If you are using FileZilla you should be able to see the FTP directory on the right-hand pane, just above the folder list. Copy this and paste it into Akeeba Backup's edit box, then append any variables you need to use.
The FTP engine, unlike the other post-processing engines, does not support creating directories, therefore you can't use the variables, such as [DATE], [TIME] and [HOST] in the directory's name. The reason is pretty simple. Cloud servers handle directory creation automatically. With FTP we'd have to list the parent directory's contents and create the directory if it doesn't exist. During our testing we found out that this causes great problems on many server setups, so we decided to abandon this approach and simply allow only pre-existing directories to be used.
