<b>backup and restoring partitions</b>
|

|
|
|

|
|
You always wonder how to make a backup of a complete disk? For example to rescue
|
||
|
|
the disk, or you want to save te data for later on? Or mayby to make an image
|
||
|
|
and distribute it over a lot of computers? Here is how.
|
||
|
|
|
||
|
|
Make a backup of a partition (this could also be the whole disk):
|
||
|
|
|
||
|
|
One-to-one:
|
||
|
|
dd if=/dev/hdx1 of=/path/to/image
|
||
|
|
|
||
|
|
To a compressed image:
|
||
|
|
dd if=/dev/hdx2 | gzip > /path/to/image.gz
|
||
|
|
|
||
|
|
To mount the partition on a local directory:
|
||
|
|
mount -o loop /path/to/image /mnt
|
||
|
|
|
||
|
|
To restore a partition (first make sure the partition on disk is the same size or
|
||
|
|
bigger than the original):
|
||
|
|
|
||
|
|
One-to-one:
|
||
|
|
dd if=/path/to/image of=/dev/hdx1
|
||
|
|
|
||
|
|
From a compressed image:
|
||
|
|
gzip -dc /path/to/image.gz |dd of=/dev/hdx2
