if I'm backing up to an external drive, is there any reason to not use FAT other then FAT's file size/naming issues? It would be nice to be able to access the content on windows/mac but i'm not sure if there's any reason i have to use ext4 to backup with ubuntu files. This is really only for documents/photos/videos I have on the system.
Ubuntu – backup drive: ext4 / FAT

Generally this can be done but there are some disadvantages:
As an alternative you can install an ext3 driver on Mac/Windows or use NTFS (which doesn't suffer from problems number 1 and 4).
