Using clonezilla - how long should it take?

  • 772

So I've just setup a brand new box and thought it would be a good time to make an image with Clonezilla.

The harddrive is 250GB with ~4GB used on the partition that I have chosen to backup, so I plugged in a 16GB USB stick to store the image on, which should be sufficient (?).

But it appears that it will take more or less about 4 hours to create the image with Clonezilla. Should it really take that long to create an image of 4GB of data?

Thanks

    There really isn't a canonical answer to this since it would depend on disk subsystem speeds, fragmentation, etc. so it doesn't quite fit this format well.

    That said, if it's a "clone" of the drive, it will try to copy the entire drive, sector by sector. The way to get the end image smaller is to compress it.

    Backups are generally done at the file level. Clones/images are drive level. You probably need to use either cloning with compression or a true backup program that will copy files and compress the files, not the resulting filesystem image file.

    Another thing to check since you mentioned partimage is what filesystem you have on the USB drive. Even if it's a 16 gig drive, if the filesystem can't handle a single 4 gig file, the clone may fail and some open source programs do not handle failure gracefully...you might have been sitting for four hours with a program that's not even running anymore or is "stuck".

  2. Make sure that your partition is clean and if not check it and repair before the clone. In my case the clone was stuck in my first attempt, after stopping, repairing partition, clone processed was completed, of course, not so fast, it took 7hrs for 1GB on a linux machine with 4GB

  3. I'm a linux advocate (which means I've come to absolutely love the system and our computer shop has for the past 2+ years simply refused to install windows...because we can), that said:

    I use acronis to clone a drive that will not need any recovery later.

    But for those times when a drive has bad sectors or other error I trust the dd command (dd if=/???/??? of=/???/???)

    How long will a 250gb hd take to clone?

    Answer: No answer, just a bunch of questions such as; Are there errors on either drive? Lots of data? does it or will it require any recovery of erased data later? How much ram and what's the processing speed of the unit you are working with to accomplish the feat? what type of data is predominant on the base drive?
    .... and the list could go on for two days.

    3hours seems about average for us on a 250gb hd (preferably done by removing the drives and placing them in a work machine...preferably NOT usb).

    Hope this helps someone.
