Hi all, So I'm working on this and ran into a couple of questions about tar. 1) I'm having trouble figuring how to best run tar. I end up with files at the wrong level every time so far. Assume I first mount a partition that's empty, and then mount a partition I want to save that contains a number of system directories - /, tmp, etc. lib, mnt and others: mount /dev/sda8 /mnt/gentoo [[ This is empty except for a mount point called TarPoint ]] cd /mnt/gentoo mount /dev/sda5 TarPoint [[ The partition I want to backup ]] Now I can see all my directories under TarPoint. What's the best way to run tar, creating a file called SYSTEM.tar.bz2 in /mnt/gentoo, so that later, when I have an empty partition on a different hard drive (hda) where I'm going to restore the system, I can do this mount /dev/hda11 /mnt/gentoo cd /mnt/gentoo scp [EMAIL PROTECTED]:SYSTEM.tar.bz2 . tar xvfp SYSTEM.tar.bz2 and I get the system directory hierarchy back again. 2) This laptop is a dual boot machine so the system clock is set to local when I'm in my Gentoo environment. When I drop into the install CD I presume it's set to UTC as is the standard. My question has to do with any requirements to setting time prior to making the tar ball or untarring to build the environment. What I'm seeing is that the command tar xcjf SYSTEM.tar.bz2 generates lots of messages about file times being in the future. Maybe this won't matter if I use the backup later than 8 hours from the time I make it but in the short term will it cause any problems? Thanks, Mark -- gentoo-user@lists.gentoo.org mailing list
