System information

Note

If using standard redirection, the '-f' option must be passed separately.

# dump -0u -f - /dev/sda1 | ssh root@ remoteserver.example.com dd

of=/tmp/sda1.dump

1. If you are restoring an operating system partition, bootup your system into Rescue Mode.

This step is not required for ordinary data partitions.

2. Rebuild sda1/sda2/sda3/sda4/sda5 by using the fd isk command.

Note

If necessary, create the partitions to contain the restored file systems. The new

partitions must be large enough to contain the restored data. It is important to get the

start and end numbers right; these are the starting and ending sector numbers of the

partitions.

3. Format the destination partitions by using the mkfs command, as shown below.

Important

DO NOT format /d ev/sd a6 in the above example because it saves backup files.

# mkfs.ext3 /dev/sda1

# mkfs.ext3 /dev/sda2

# mkfs.ext3 /dev/sda3

4. If creating new partitions, re-label all the partitions so they match the fstab file. This step is

not required if the partitions are not being recreated.

# e2label /dev/sda1 /boot1

# e2label /dev/sda2 /

# e2label /dev/sda3 /data

# mkswap -L SWAP-sda5 /dev/sda5

5. Prepare the working directories.

# mkdir /mnt/sda1

# mount -t ext3 /dev/sda1 /mnt/sda1

# mkdir /mnt/sda2

# mount -t ext3 /dev/sda2 /mnt/sda2
