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 |

Regarding the perfmance of partclone: Look at the "on-the-fly performance" Thread in this mailing list. 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.

Yes, Thomas Tsai is working on the improvement of partclone. Lukas, Please send us gprof results you have. Thanks. Steven.

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.

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 ;)

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.

Lukas

Thanks for the explanation. > BTW, which version of Clonezilla live are you using? Did you try 1.2.5-1? I tried the latest stable (1.2.4-28). Hmm ok I'll give 1.2.5-1 a try and will report back.

Here are the test results: For both tests, I used the following: - partition image backup to SSH server thru Gigabit link - Filessytem: ext3 - Device size: 58 GB - Space in use: 3.5 GB - Block size: 4096 bytes - size in MB to split partition image: 1000000 (to avoid split) - Compression on image: none - the rest of settings were default ones For the above scenario, the times were: a) Using clonezilla-live-1.2.4-28-686.iso, it took 8 minutes and 5 seconds b) Using clonezilla-live-1.2.5-2.686.iso, it took 2 minutes and 31 seconds The elapsed time above is just after hitting "Are you sure ..." where you press "y" until the end of the image creation + hw gathering info output etc, specifically "Press Enter to continue...". Impressive really. Excellent job guys! So when does "testing" becomes "stable". Is it based on some time or is it if it's been there for some time without many people reporting any issues? All the best, Jorge |

If people report any issue, definitely we will do our best to fix it. Actually if the version you are using did the job for you, stick with it.
