More often than not that results in you needing twice as much disk space as what you actually use, few people are willing to sacrifice that much. Consider: /usr 8G /home 100G+ everything else - much less space That's not unusual for people's personal machines. At some point you will need 100G free for a backup copy. Less if you pipe tar to gzip, but the actual amount is always unknown till you do it. The only amount certain to work is 100G if the data is binary with no benefit from compression. Push backups are indeed the better route for the OP with a simple setup. -- alan dot mckinnon at gmail dot com
