Hello. I recently added a Mac mini to my network. One of the things that I am missing from the Windows world is a way to backup my data. This is what I currently do on my Windows machine, and I'd like a way to do it on the Mac. 1. Backup my data using NTBackup to an external HDD. This creates a backup image, and the files inside the image are then verified against the original copies. 2. Copy the files to DVD using RecordNow, which burns to DVD and then verifies each file on the completed DVD against the original copies. This way I have a HDD backup I keep at my apartment, and a DVD backup I keep at another location, and I am sure that both are valid backups. Is there a way to do this on the Mac? I have to have a way to verify that the backup on the external drive and the DVD? What is the best way to do this? Does creating a disk image verify the .iso after it is created? Does it verify the CD/DVD once it is burned? Another option is TAR, but I would rather stay in the GUI, and away from the terminal. How does everybody else backup their data, and make sure it's a valid backup? Thanks.
