Harry was asking about going between two machines. I did something |
| 53 |
similar recently ((http://blog.garrysmith.net/?p=62#more-62) and used |
| 54 |
the following command to pass the output from tar directly to the |
| 55 |
destination machine over SSH: |
| 56 |
|
| 57 |
tar -cvzpf - ./bin ./boot ./dev ./etc ./lib ./lost+found ./media ./mnt |
| 58 |
./opt ./proc ./root ./sbin ./sys ./usr ./var | ssh -p8889 |
| 59 |
root@192.168.1.69 “cd /mnt/gentoo; tar -xzpf -” |
| 60 |
|
| 61 |
Unfortunately the symbolic links all came out as 0 byte files (not sym |
| 62 |
links), so in the end I fell back on rsync (over SSH) which did the job. |
| 63 |
|
| 64 |
How do you normally preserve symlinks using tar piped over SSH? |
| 65 |
|
| 66 |
An example of the rsync command I used was: |
| 67 |
|
| 68 |
rsync -avpe "ssh -p 8889" /home user@×××××××××××.machine:/mnt/gentoo |
| 69 |
|
| 70 |
|
| 71 |
The next time that I do this, I will just use rsync straight away and |
| 72 |
not use tar. The Gentoo Live CD has rsync (the Gentoo minimal install |
| 73 |
doesn't), so you should use the former (I booted both machines (one of |
| 74 |
them within VMWare fusion) from live the CD in order to do the copy. |
