I have a LaCie NAS that is not compatible with Time Machine. I used to use Deja Vu to back up the software, but I messed it up by loading a trial version and cannot find my original disk. When I back up from my startup disk to the NAS, both Deja Vu and PsyncX create a huge file that takes up all of the remaining space on my startup drive (150 GB with 45 GB free). When Deja Vu finally completes the process and I restart, it deletes the file. PsyncX does not so I manually delete it. Deja Vu will not respond to my request for help - I think nobody is home any more at that store. My trial expired and I will not buy something that does not work (silly me). Is there any backup software out there that allows me to backup changed files to a NAS and run unattended on a scheduled basis?
