The problem was that I do backups of ~/ (kept on a separate partition) only when there have been significant changes. In the present case I had done a backup before the dist-upgrade from 13.10 to 14.04.1 a couple weeks ago. That dist-upgrade turned out to be such a disaster that ultimately the OS would not even boot. My only choice was a fresh install. The first two installs left me with a hopelessly broken X; so badly broken that I could not do the backup from within the running OS. I decided to make another backup of ~/ before continuing because the install utility in Xubuntu 14.04.1 was very confusing. I was worried that I might accidentally mess up the ~/ partition in the process. But I had to do the backup from a live CD, and the GUI file managers would not let me drag and drop due to permission problems. Even cp from the command line gave me permission errors. The ~/ partition is on an SSD and holds about 250 MB of data. I was copying to an external USB 3.0 device and all the USB ports on the computer are 3.0. The entire cp command took about 15 minutes. And before anyone tells my I am a fool for not using rsync or other fancy tools run from a cron job, I don't make that many changes. If I really am working on a significant project where I need to back up the work daily or even more often I use a USB stick for a temporary backup. And for my once-in-a-while full backups of ~/ I have an rdiff-backup script which I could not use in this case because I was not in the OS. The ensuing discussion of sudo v. su etc. is interesting, but my problem is already solved. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
