The backup of my Soekris 4801
I've read an article about Unix system administration recently. One of
the golden rules, if I remember correctly it was the first one, is
backup your systems regulary. Backup - stop reading this article, think
of a backup. Well, I read the article till the end and looked at my
laptop - no backup. I looked at my Soekris - no backup, I looked at my
NetBSD toaster - no backup. Huh, time to do something like a backup. I
decided to look at all the fancy tools for this task like: bacula,
arkaya and several others. A posting from Mathias Scheler on -current
users brought the idea: why not use dump(8) for this purpose?
#!/bin/ksh # # Full Dump of Soekris TIMESTAMP=$(date "+%Y.%m.%d-%H%M") DMPFILE=/server/$TIMESTAMP-Soekris_Dump.dmp dump -0uan -f - / | ssh rhaen@wiesel "dd of=$DMPFILE"Voila - a level 0 dump using ssh to a different server. A restore test showed that this concept is working well. I'll setup a cron for this and dump on an external USB device. Did I mention I love the Soekris USB port of the 4801?
