Backups
Create a Knoppix CD-ROM disk
A Knoppix CD-ROM is a bootable disk that boots a Linux without
touching a system's hard drive. Use it for doing system tasks
like copying the system hard disk to an external hard disk. Get
the 700MB Knoppix ISO image from the Knoppix web site. Save it
somewhere. Then:
This works on netserver:
mount a blank CD-R or CD-RW *WITH 700mb size* in netserver's drive
as root
cdrecord -v speed=10 dev=1,0,0 KNOPPIX_V3.3-2004-02-09-EN.iso
This doesn't work, but should, on Gazelle:
as root
/etc/emperor/cdrw start
cdrecord -dummy -v speed=16 dev=0,0,0 KNOPPIX_V3.3-2004-02-09-EN.iso
/etc/emperor/cdrw stop
Backup to USB disk
See the notes on my
USB Disk cradle page for how to set up an
external USB cradle disk drive. Then boot the Knoppix disk.
Then to copy hda to sdb, do
dd if=/dev/hda of=/dev/sdb bs=10M
That took 4 hours. Play with the 1M value to speed it up. Is it
doing USB 2 speed?
Backups on netserver
I used to use Mark Uris's artoms and msrestore programs.
As of July 2009, I rely on David Mitchell's "snapshots".
See the netserver snapshots page.
