Re: Backups to CD

[Sebastiaan <sebas@sacred-key.org>]

Hi,

I think the simplest way is to use dd. I made a backup with:
dd if=/dev/sdb bs=2048 count=700000 | gzip -v > backup_cd1.img.gz
dd if=/dev/sdb bs=2048 skip=700000  | gzip -v > backup_cd2.img.gz

To put it back, mount the cd's and:
gunzip -cd backup_cd1.img.gz | dd of=/dev/sdb bs=2048 count=700000
gunzip -cd backup_cd2.img.gz | dd of=/dev/sdb bs=2048 seek=700000

Hope it helps,
Greetz,
Sebastiaan
