That misses the point. This isn't really about making backups, it's about learning to write shell scripts. Backing up is just the project that Dale has chosen for this first effort, at least that's how I read it. Having said that, you need an underlying program to perform the backups, and the main choices are tar and rsync. Rsync has all the advantages already mentioned, but it does need a lot of space and needs the filesystem to be used for backups to support all the metadata of the source. Tar handles both of these issues, but incremental backups are more complicated to make and restore. On the other hand, you do get history, while rsync only has the most recent copy of the file. If you found the file was corrupt just after an rsync backup, touch! I really like BackupPC, but that's totally irrelevant to the original question. -- Neil Bothwick We all know what comes after 'X', said Tom, wisely.
