Perhaps I'm not explaining what I'm trying to do very clearly. Let me try again.
Grsync looked very promising, but I couldn't get it to work the way I wanted. For example: My home folder contains fifteen sub-folders and three files. Some of these sub-folders also have sub-folders. I would like to backup five of those sub-folders into a compressed backup file on an external hard drive. I would like to be able to save the selected folders & files as a 'job', so that the next time I do a backup, I don't have to remember which folders & files to select. Working with the documentation for grsync, I was only able to select one folder at at time. This will eventually get the job done, but it is not very efficient. Also if I understood the documentation correctly, rsync is really designed for keeping files synchronized on two or more computers (i.e. your desktop & your notebook); not for making backups.
I hope this helps you understand my problem a little better.
Try lucky Backup. Here I have in one task selected three sub directories from my /home/polack directory to backup to my external hard drive. There are also three restore functions, one for each. By checking all the directories and running the task all three, including their sub directories, are fully backed up into a single directory on the external drive. If I delete the original directories entirely, uncheck the three backup boxes, and check the three restore boxes, all my files are restored to the /home/polack directory.
I did this on the default task list. You can create as many new task lists (Profiles) as you chose and name them what you will. You can include any number of individual directories from various locations, each as a complete directory, by name, or just the contents of the directory. You can direct the backup to any location you can reach.
I don't normally use this application as I use rsync direct from the command line. I installed it just to run this test. Clicking Help to read the handbook for lucky Backup got nothing, but this app is so drop dead simple, no handbook is really needed. I've done the backup, deleted the originals, and run the restores. Everything works exactly as advertised.
