Re: [Clonezilla-live] Partclone vs Partimage
Lukas,
Thanks. Thomas Tsai will revise this and try to use them.
In the future, we will have more options in partclone to disable some
jobs, e.g. -q, --quiet to skip all the rate messages update.
Thanks.
Steven.

As I understood the code, -f only affects the time the gui itself would

anyway is run.
Thanks. I will check with Thomas,
No problem.
You can see it e.g. here in restore.c :
/// start restore image file to partition
for( block_id = 0; block_id image_hdr.totalblock; block_id++ ){
/* doing things, copying the blocks */
update_pui(prog, copied, done);
} // end of for
I did a patch for myself within I told it just call update_pui once for
5000 blocks. Don't know if its a good idea, but it worked ;)
Good, and the performance is?
Could you please also send us the patch file?
Thanks.
I got about 20-39 MB/s.
Here is the patch. There are some other changes within:
* I completeley disabled the update_pui on the server side, because
clonezilla anyway doesn't show the output there.
* I changed the display of the speed from */min to */s beaucse I thoght
it's better readable for the most people.
* I implemented that crc32-checks can be disabled. Not an good idea, but
I wanted it for testing and its disabled by default.
Sorry, I had no time to rip off these other changes but it should be ok
anyway I hope.
Regards,
Lukas
Steven.
If I've time I'll try the older clonezilla live, too.
BTW, maybe you can also give Clonezilla live 1.2.2-14 a try? It's
partclone is older, and we might have a regression somewhere...
Please let us know the results.
Thanks.
Regards,
Steven.

Partclone does some odd things which slow down the speed. You can
improve this by saying not to use the gui. (I think this is in the
expert options). But it stills does stupid things, like
calculating the
speed too often which resultes in high cpu load.

Hello Steven,
I've been using Clonezilla happily for more than 2 years and I
always used the
custom options and specifically partimage as the cloning tool.
Since partimage
seems to be a dead project (and no support for ext4) and
considering that
Clonezilla uses partclone as the default option I decided to use
this.
My observation was that partclone takes some more time. When it
started
saving the partition, I wasn't sure what it was doing. There was
some
progress indicator (percentage) (Generating bitmap..) and I after
that it
started again another progress indicator (I guess the actual
creation of the
image). I'm a bit confused about these 2 steps as soon as
partclone starts.
Any tip will be appreciated. (just curious).
Thanks for Clonezillla.
Best regards,
Jorge
