I'd say 100 megs of space, to be served by a directory amanda would ignore on the 2T drive it uses for nightly's would be a great plenty for working on a machine configuration stuffs. Thats what this align thingy basically is. And in this case, I am inclined to think diff might be the tool. Basically do a full when deciding that its stable enough to be used for further testing, an anchorpoint, then anytime a change write is done, generate a new diff. > > > I'm forced to comment here, because while I am a long term (about 20 > > years now) user of amanda, so I am quite familiar with its concept > > of doing a level 0 within the timeframe of runspercycle, usually > > stated in days, with a chefs choice of backup levels out to 4 or 5 > > used in between fulls, with an eye toward adjusting the schedule to > > always use the same amount of storage on the media during an > > individual run. > > > > > > But no one has mentioned the name of something that will backup only > > the changes, that can be started in the background to accomplish > > this instant incremental backup while one is working on a project. > > Does linux actually have such a beast?

Since this box has spinning rust, tons of it on a 1T drive, I've made a backup dir in /home/gene, and will see if I can configure it to backup only 2 directories, the home configdir for this new machine, and the nc_files and deeper. Or, since the gui shows progile selections, it looks as if that could be 2 separate backups. Then see if inotifywait can be used as a trigger. Looks like fun & surprises, help, since theres none in the manpage, in configuring this toy appreciated. Thanks.
