Re: AW: [Voyage-linux] Problem to make a backup from CF-Card
What I do is backup the MBR and partitions separately. Usually voyage (or sometimes open-wrt) do not take up the whole CF card. dd if=/dev/sda of=/path/to/alix.MBR.img count=1 bs=446 This copies the MBR but not the partition table (I do not always have the same partition layout). Then I backup the voyage install ddrescue /dev/sda1 /path/to/alix.sda1.img When restoring I partition the new card, and then copy the MBR and backed up partition. I create any secondary partitions after this step. dd if=/path/to/alix.MBR.img of=/dev/sdb count=1 bs=446 ddrescue /path/to/alix.sda1.img /dev/sdb1 The reason I do this is that I have a number of differently sized cards, but in almost all cases the voyage or open-wrt install is a couple of hundred megs while the CF cards are usually between 2 and 8 GB. I can use the same image on all these cards without worrying too much about the total size of the CF cards. If you want to backup the whole drive and you are sure that the drives are exactly the same (even though they are both 8 GB, they may not be exactly the same, down to the last byte), I usually just use ddrescue. Your situation indicates that GRUB is corrupt. You may be able to just copy the MBR from the old CF to the new. dd if=/dev/sda of=/path/to/alix.MBR.img count=1 bs=446 and then reverse that to copy it to the new CF card. Failing that, try using ddrescue to image the whole CF card. Hth, On 10-08-31 04:29 AM, Pfau, Jens (SMT GmbH) wrote: > Yes it´s the same machine. I use new Kingston 8GB CF-Cards (CF/8GB).
