Sorry all, the previous mail was sent prematurely... Hi all, Over the past few weeks I have been setting up and tweaking DUMP to dump each of my 4 main filesystems (/ /var /home /usr). Progress is going well (currently set to do full dump 1x per week and do a level 1 each night). I still have a couple of questions. First, I am dumping all 4 filesystems to /home/backup. I have the nodump flag set for the /home/backup directory, and so for it seems to honor it for all the files in that directory (which is what I want, so as to avois dumping previous dumps inside that directory). My question here is, if I read the man correctly, it SHOULD recursively not dump all files in that directory, is this correct? Second, I want to add a second drive. Currently, this box only has 3 SCSI drives on a RAID 5 card. My question is, when I add the second drive (which will be an IDE drive about 40 GIG), can I configure it to take the dumps directly, so as to create a mirror drive. So here is what I 'want' to happen: Each Monday early morning: dump writes full a full backup of / to /dev/ad0s1/ Each Monday early morning: dump writes full a full backup of /usr to /dev/ad0s1/usr Each Monday early morning: dump writes full a full backup of /var to /dev/ad0s1/var Each Monday early morning: dump writes full a full backup of /home to /dev/ad0s1/home Then, at early morning of all other days, incremental backups (changed files only) are written to the correct destination directories on the second drive. In effect, I want to create a mirror, will this work, and would the command lines (in cron) look like: dump -0u -h0 -f /dev/ad0s1 / dump -0u -h0 -f /dev/ad0s1/var /var dump -0u -h0 -f /dev/ad0s1/usr /usr dump -0u -h0 -f /dev/ad0s1/home /home An the last question is, if I want to make the second drive bootable (in the event the raid system dies), do I need to load (from scratch) the OS (FreeBSD 4.4) on the new drive first, or, just partition and disklabel it creating the needed filesystems?
