Other Help Topics :: Backing up to HDD

I have a running DSL system with which I would like to back up the ramdisk to a hard drive (reiserfs, DSL will mount it). The backup code will only back up to a usb drive (I have one big enough, but it's dead) or a floppy (with Firebird? No way in heck!) How do I trick DSL into thinking that /mnt/hdb1/dslbackup is a backup device, or better yet, trick it into thinking that it's /ramdisk?

Try these commands at the console:

tar -c /ramdisk > /mnt/hdb1/backup
bzip2 /mnt/hdb1/backup

That will give you backup.bz2 which can be extracted into /ramdisk again when you next boot.
