 |
|
I was wondering how I could make an exact copy of the data on my reiserfs partition.
I read some time ago that I just should use tar but I forgot what command exactly.
What I want is to tar/copy the data to my 250GB disk, make a jfs partition on the other (which currently has reiserfs) and then tar/copy the data back from the 250GB disk. Also, I think it's best that the access/modify times and owners should stay as they are.
Does anyone know what I should do ?
Btw, the 250GB disk is a SATA one.
Thanks in advance  |

you might try man tar 
| Code: | | tar cjvpf /path/to/backup.tar.bz2 /path/to/data |
c: creates archive
j: compresses archive using bzip2
v: verbosity level 1
p: preserve all permissions
f: to specify archive name

Now I only wonder if the gentoo installation cd has support for SATA, the via chipset that is.
That's because I want to boot from the livecd so nothing on my primary harddisk changes and I can just copy all stuff to the SATA disk
Btw, I noted that cp -r --preserve=all foobar/ ./ also works fine to make a backup. Or am I missing something? I'd like to know |

if you want an exact copy bit for bit, use dd. dd if=/source/partion/ of=/target/partion bs=4096 conv=notrunc,noerrors
The target partion will have to be the same size or larger. |
